2016 Nissan Titan XD Gas vs Diesel, Towing vs Empty Highway MPG Review

[@xXBurntBaconXx]

Diesel no Trailer: 19.5 mpg Diesel w/ 7000lbs: 10.7 mpg Gas no Trailer: 17mpg Gas w/ 7000lbs 9.5 mpg F150 3.5L Ecoboost w/ 7000lbs 8.5mpg

[@turbodiesel4709]

Good call xXBurntBaconXx: It's pretty obvious isn't it? Hell, even all emissioned up, it's still the DIESEL for the WIN! Figure out how to bypass all that emissions crap, that they keep slapping on modern diesels, and you'll pickup more fuel economy and performance from that diesel. It's been proven time and time again over the years.

[@aj06bolt12r]

Factor in the huge price premium over the gas engine. Then factor in all the repair bills when that diesel gets some miles and the egr coolers fail. When the diesel particulate filter fails, when the scr system fails. You will be money ahead buying the gas engine by far. And the gas engine is faster up the IKE!

[@t3chfr3ak]

aj06bolt12r and add in the added cost of buy DEF, which seems to drink the shit going by user reviews.

[@THX..1138]

Diesel engines usually get bad fuel economy when new, they're not fully broke in till about 70,000 miles. I would expect if they ran the same test a year or two later the diesel would pickup at least a couple of MPG.

[@brotherheed00]

Inferno Beast I heard this mentioned when I bought my Harley. Lol. I saw no difference when paying for the up front cost vs when selling that thing on the back side. The higher resale didn’t out weigh the up front cost.

[@mohammedkhan11]

so these two Nissan beat the ford 3.5l ecoboost f150 on MPG

[@melodygarrett573]

This is the informative testing that we all need! Real world, everyday driven testing is the only comparative way to know what is available in the truck market. Would be curious to know what the test numbers would be for all makes of trucks across the board. I believe most of us would gain insight into what MPG we would actually get with this kind of testing. In this economy, where every penny counts, we need this information to make an informative and subjective decision. Great job guys and keep up the outstanding work you do for us all!

[@quadrunner2124]

TFL, You guys are doing a great job, and I really value these reviews for my future purchasing decisions. Thank You so much for your time and effort. Here is how you could do even better. 1. Note, the mileage of the vehicles that you are testing. Its something we should know. 2. Validate with the company there is no detuned system to aid break in. 3. At the beginning and/or end of the video, provide a quick list of applicable options and specs like weight, off road packages, axle ratios etc... That way I don't have to scroll through the video if I forgot something PS...if you are talking Diesel vs Gas savings, its best to consider resale value into the equation and it would not hurt to remind people of the big picture for their big decisions. Truck buyers who plan to trade in down the road account for the higher value, (usually at least the cost of the diesel option) of their diesel trucks. Since New vs Resale is the highest cost of a vehicle for the majority of drivers, I believe its at least worth noting now and again. Additionally, you did not factor DPF into the equation for your diesel mileage. You never do....

[@CJIEngineering]

Diesel vs Gas discussion, the diesel engine will be worth much more when you go to trade in or sell the truck so you do not need to save the $5k in fuel alone. It is true they cost more to maintain so it really boils down to do you like to drive torque or horsepower? I personally love to run diesel engines, low rpm stump pulling power and better economy in all situations.... Nice job guys.

[@wtgkb8]

The V8 gas Titan XD got 1.1 mpg better than the previous test with the 2016 F150 3.5L Ecoboost towing the same trailer (9.6 mpg Titan vs the 8.5 mpg F150). Kinda surprising given how much heavier the Titan XD is compared to that F150. Those turbos were working hard.

[@VortexVibe634]

True, but they got the worst F150 for towing and it had like 22" wheels

[@mdbangsund]

+MrKamakura77 the XD LE diesel has 20's on it. most people will have 18's or 20'on there trucks.

[@NavyCuda]

The premium of diesel over gasoline engine costs isn't as much of a factor if you intend to trade the truck in later in its life. Diesels command a better resale value.

[@larry8065]

And why do they command better resale value? Because morons are willing to pay way more for something they THINK is way better....even though this video just proves that notion isn't really true.

[@joenissan]

Lmao!!! Really? Did we forget that you ALREADY PAID THE EXTRA 5g FOR THE DIESEL?! You'll never get that back and with on a mile or two per gallon difference, you'll be paying MUCH more in the long run since diesel is more expensive at the pump. C'mon people, it's easy math. Unless you feel more manly with an engine that sounds like it's got marbles in it, it makes no sense.

[@joenissan]

+carbonking53 Longevity has been a non issue ever since gas V8s have been easily going over 200k miles. Unless you're an over the road trucker who needs to last a million miles, most don't keep vehicles that long anyhow. As for quieter towing, lol.....not sure what you've been towing with, but even with higher gas engine RPMs during hill climbs, the diesel is still louder, although they've gotten better. Like I said, especially for this class, diesel makes sense only to those who feel they get an extra "man card" by driving one, and are bad at math.

[@joenissan]

+john roark you've apparently not seen any of the reviews. Quite the contrary in fact. The gasser feels far more spry, even while towing the gauntlet . The diesel tows 1000 lbs more while the gasser has a 550 lbs payload advantage.

[@joenissan]

The gauntlet test was the same exact 10k weight. My point isn't necessarily a gas vs diesel in general, but this particular truck/engine combo. I've been towing for well over 30 years and I agree, in general diesels are the heavy haulers. But it this case, Nissans Endurance handles just fine and in this case, maybe better.

[@ozy311]

Always great videos, but don't forget that the diesel will keep its value much longer than the gas model will.

[@Funky4me21]

Until people realize what a failure it is. That is why Nissan quite selling the garbage.. I have one parked in my driveway due to the exhaust system costing $4000 after only 23, thousand miles.

[@justinp8946]

I actually like these trucks, they're growing on me. The gas version got a tad higher mpg than the ecoboost.

[@crazyhass84]

agreed. eco boost is not so eco. what a joke. but hey the ford will back your trailer for u...LMAO

[@justinp8946]

+Andy Hass I love f150, but not that impressed with the ecoboost. 5.0 coyote all day

[@cwm180]

The EcoBoost they tested was the heaviest version available with 22" wheels, i.e. not representative of what an XLT would do. Most people have an XLT or Lariat, not the Limited.

[@arbiter1]

Most other trucks they test are the heaviest or their lineup so saying is not a good representative is kinda wrong. Turbo needs to be under under load to produce the boost the engine needs to make its power which means it needs to run more throttle then a naturally aspirated truck.

[@noblekitty]

It doesn't have to run more throttle or anything. If you look at all the truck towing comparisons, the ecoboost engine always operate at the lower RPM vs other N/A v8s. How's that equate to more throttle? The boost from the turbo allows the engine to get more oxygen. More oxygen leads to more fuel can be injected each stroke. which leads to more torque per stroke. More torque means less RPM to produce the same amount of horsepower vs less torque engine which needs higher RPM. However, less RPM =/= less fuel consumption. It takes horsepower to perform certain task of work. And it takes X amount of fuel to produce X amount of Horsepower. Most gasoline engines nowadays are very similar in efficiency as in the amount of kinetic energy they can extract from fuel, which is about 30-35%. There are many other factors which will affect MPG, beside the engine alone. Have they considered the wind speed and direction on the route? or the time it takes each truck to reach 70 mph? accelerate faster costs more energy. Wind drags costs energy, quite a bit in fact. After all, the point of making the ecoboost F150 is for 90% of consumers who rarely tow with their trucks. For those rare instance of towing, do you think they would die over a 1 mpg differences (if that's even true, since TFLTruck didn't measure the wind speed and direction on different test days). When they are not towing, the ecoboost 4x4 F150 is rated for 22 mpg vs the 4x4 XD Titan 18 mpg highway. If you plan to tow everyday, you already made a mistake buying a gasoline powered pickup, let alone deciding between the ecoboost or N/A V8s.

[@davva360]

I am not anti diesel, i own a diesel RAM 2500 and a gas F250 and I have said this for years. Diesels only make sense if you do a lot of miles. The up front cost difference is a lot to make up when you are only looking at about 10% better mpg. If you tow a lot, and I mean almost every day and plan to put a lot of miles on it , the diesel may be a better bet, but if you do not, gas is the way to go.

[@jaysmith1408]

And or or? Tow and miles or tow or miles. I run massive distances but almost never tow great weight.

[@davva360]

In my area you would never make up the cost with miles because while diesel gets about 10% better mpg the fuel costs about 10% more so it is a wash. I know it is not the same everywhere though so in some places you can make up the initial cost in mpg, as long as you do a lot of miles.

[@unknownunknowns]

davva360 But what about maintenance since diesels are generally lower?

[@Chuckers84]

Stefan Unson still wouldn't make up for it gasoline engines have come along way and there is very little maintenance involved when maintain properly plus diesel maintenance is quite a bit more expensive. The amount of oil used in the diesels is significantly more and the filters are expensive to say the least

[@davva360]

I don't agree diesels are cheaper to maintain at all. Oil changes for example. If you go by recommended intervals the diesel will go further between changes but the oil change will cost at least twice as much as it uses twice as much oil. Diesels now also require DEF and usually a fuel filter change at every oil change. My gas truck is $30 per oil change every 7500 miles. My diesel is $90 to do an oil change every 15000 miles (recommended, i never go over 10k).

[@mauricemotors8207]

That pro 4x and the body coloring looks badass!

[@Cobb]

It always surprises me when the diesel doesn't get at least 3-5 mpg better than the gas.

[@chrisbaker2903]

Note they had different transmission and rear end ratios. That can make a huge difference. But their speed also tends to equalize things because the aerodynamic drag becomes a greater factor when you up the speed.

[@douglas685]

It's probably because the 5.6l V8 is tuned for at least decent mpg since it's also used in the regular truck (which is EPA rated) and the diesel is a cummins which isn't. Cummins and Nissan were probably "eh" on mpg tuning for it, and more tuned it for power and usability

[@johnwesley1660]

Awesome comparison! After seeing this video I don't think it would be beneficial to purchase the diesel over the gas.

[@darrensaunders4635]

I have a gas XD PR. Should have gotten diesel. 7 speeds so it's always looking for the right gear. Constantly dropping vs building boost. Weird flat spot in power band at about 3000rpm. But I do get 16mpg on the hwy with 3" lift and 34s in a hilly part of Canada. No performance aftermarket though.

[@Funky4me21]

No benefit at all... I thought it might be until reading Darren Saunders comment below..

[@robacejr]

WELL IM GLAD I BOUGHT A DIESEL! TITAN XD Just go my windows TINTED!

[@ChrisHairMusic]

It’s been 8 years… How was this truck for you?

[@waynerhea6649]

The reason for that 5000 dollar premium for the diesel is because of how easy it will tow the weight. Even though the diesel tow only 1000 pounds more the way it does it is way more confident. The truck is limited by the chassis and other things rather than the power of the engine.if you plan on towing the diesel will make it so much easier while returning better mpg and longer longevity.

[@tbone-ml4ex]

I have a 5.9 cummins, 2004.5. When I first bought it i was only getting around 16 mpg. after about 20,000 miles i was getting high 18's to 19 mpg. at 90,000 miles it gets between 21 and 22 mpg not towing. I have heard others having the same experience with their diesels. This is at between 3,000 and 4,000 feet elevation.

[@dylanmacaya9166]

They definitely need extra time (read mileage) to break in well and loosen up to achieve their maximum best fuel mileage. I think the XD Cummins in this test only has about 8000 miles on it. It will continue to do considerably better MPG numbers as is it doubles, triples, and quadruples its mileage. Both in laden and unladen tests.

[@turbodiesel4709]

Hey TFL Truck: Thanks for this test boys. Just re-confirms that I need to stick with my 2002 Dodge Ram 2500HD quad cab short bed 4x4 with the 24V 5.9L Cummins Turbo Diesel & 6-spd manual trans with 3.55 rear axle ratio for as long as I possibly can. She's simply more capable, more powerful, & more fuel efficient, whether unloaded or loaded. Today's new trucks just keep proving to me that they are simply a total waste of money.

[@MrJwh3000]

Same here. I own a 02 Chevy 3500 6.6 Duramax 4x4 with 300,000 miles on it. It still runs perfect and thank God its paid for! I want a new truck but the newer ones seem a little to complex and unproven. I'll just replace the front wheel bearings and that'll be my new ride.

[@gamer6654]

Damn this is currently the most hyped truck!!!!

[@joenissan]

BTW, no....the Pro4X doesn’t sit taller. It’s lower in fact....but by a negligible amount. I’ve found it’s not about efficiency but HOW it feels towing. The diesel is more solid and unflappable.

[@SoundgardenMan]

I'm quite surprised how little of a difference there was between the two. Many other manufacturers seem to have a bigger difference between their gas and oil burners.

[@robgrune3284]

@TFL.. thanks guys. After 4 years, this is your first, sensible "test". The diesel achieves about 10% better economy than gas, for both conditions. Within the Nissan brand, the diesel math is simply equal to gas math, when ALL factors are considered: costs for fuel, maintenance, purchase, etc. The old argument that diesel outlasts gas is no longer relevant to this specific comparison, because the modern materials will likely ensure the gas and diesel variants will achieve equal lifespans [assuming both are not driven to extremes]. Where the diesel is supposed to excel is in the engine braking, but the diesel Titan has not this feature, and thus the advantage is lost. However, when comparing the Titan diesel to other brands, in fact a Silverado 2500 SRW Diesel achieves the same economy under same conditions, yet has much more capacity and the engine braking, for about the same price as the Titan. Thus the Titan remains imho over priced for its capabilities. Your tests for Titan and Silverado prove this assertion. IF Nissan were to install a proper engine brake on the diesel, my opinion may change: but minus this feature, the Nissan is simply not worthwhile for serious trucking.

[@robgrune3284]

update. A/ Per all TFL vids: 1/The data seems to show: a/ the ecobust gets about 8.5 mpg; b/ all V8s across all brands are averaging about 9.5 mpg; c/ the Titan XD Cummins Diesel averages about 10.5 mpg. Thus, all are highly comparable for mpg. The best for mpg is the Ram ecodiesel, but this is for very much less towing weight. 2/ The XD does have more towing capability overall than all other brands for 150/1500 segment: about 30% more. 3/ the XD is well appointed, quiet, smooth. B/ Per my dealer visits recently, the delivered price of the XD is about $8k less than MSRP; one was about $10k lower. If this pricing holds, then the XD is in fact priced competitively for the 150/1500 segment, and becomes far more attractive to me. The XD price is at the segment top, but it has the Cummins and Aisin, which are not cheap, and both cannot be questioned for reliability and strength, and both give the XD extra capability. The price premium is starting to look acceptable. C/ No dealer will yet allow me to test drive an XD with a 9k# trailer. But all dealers tell me the Cummins and Aisin work together to provide engine braking. I cannot find any info about this from Cummins or Aisin, or any web forums, so cannot confirm. But no 150/1500 truck has effective engine braking, so the XD is average or above for this. Still, I do wish Cummins or Nissan would install a proper exhaust brake: a 5L motor should be very capable to tolerate this. D/ conclusion: the XD at $8k lower is now a serious option for towing a 9k# trailer weekly.

[@brianrocha3803]

The rpms aren't going to change because the torque converter is locked. Doesn't matter what you are pulling, if you are in top gear at 70mph, the rpm will not change unless the torque converter unlocks or thw transmission downshifts.

[@jaysuper8255]

Wind resistance makes a big deal towing. I tow my 26' travel trailer, usually at 62-63 MPH. If I get a wind-less day I get 11 - 11.25 mpg. If I get a average headwind I get middle 10's. A strong headwind anywhere from 8 - 10 mpg. Best I ever got with a nice tailwind was 13 mpg. RV trailer is 10' 7' tall with a slight rack( rake?) and weighs 6000lbs. I usually can keep it in overdrive (6th) at 1750 rpm's on the flat. Gas mileage will improve about a 1/2 mpg on secondary roads where the speeds are 50 - 55 mph. Towing with a 5.7 L Tundra (2014). My last RV trailer was the same brand, one foot shorter length and 8" shorter height and I got on average one mpg better. Without towing I get 20-21 mpg highway and 15-16 city. The only issue with the Tundra I'm limited to 9900lbs. towing capacity.

[@Began2011]

Great review. I wish Nissan would offer a Titan hd dually, that would at least increase the payload capacity. And it would to me make the truck look even cooler.

[@weialles_weinix3900]

Didn't expect that result. Would have bet the Diesel would be more efficient. That speaks for the gas version. Btw a good comparison and a good video also.

[@rkalla]

Same here - especially given the price premium.

[@weialles_weinix3900]

+Riyad Kalla I ask myself will there be a larger difference at a lower speed. I'm thinking of sth about 60 or 65 mph.

[@rkalla]

You're thinking is definitely on the right track - my understanding is the high-torque diesel engines shine so well at highway speeds partly because they can cruise at super low RPMs and still pull as hard as they need to. That's why I was a little surprised by the 2k RPM on the diesel in this comparison. I've watched more Ram 1500 Ecodiesel review's than I care to admit and I feel like most of the highway MPG tests (which push near 30mpg without towing) are sitting around 12-1300 RPM. Just surprised overall at how "meh" the Cummings was in this application. Expected it to either get really solid MPG unladen OR almost identical MPG while towing (because it's relatively unbothered by the weight) and neither of those happened... it got right near gas MPG in both cases. Weird... or it's more likely I have no idea what I'm talking about and missing the point of the Cummings 5.0L :)

[@crazyhass84]

+Riyad Kalla agreed. remember the ram eco diesel has a 8speed trans which is why its at 1500rpm at 70mph vs the 5.0l cummins with a 6speed behind it. at 7k the eco diesel is the choice. at 12k towing the 5.0l cummins might be the choice. but only if it gets better mpg than a ram 2500 with the 6.7l cummins (i doubt it will).

[@rkalla]

Ahh, great points (8sp and the higher tow capacity of 5.0).

[@bamspeck]

After owning both gas and diesels, I'm more prone to diesel for the long run. Especially Cummins. I'm not one to throw my money away by buying a new fancy truck every 2-3 years. For the long run, you can't beat Cummins. You don't even have to worry about them till after 300k miles. My comments are pointless in this case because I would never own a Nissan anyway. Just my 2 cents.

[@mauricioalfredo83]

What else you spected from a fia GT1 Champion engine? VK56 was a beast on 2009 GTR GT1 and the sound its soo cool

[@dawoodk103]

Suuka !! what happened to the loaded mpg on the deisel blyaat ?

[@duncdunc76]

Gentlemen could you please elaborate on why your numbers for the Nissan Titan Diesel Ike Gauntlet runs are so different. You did it once with the yellow one towing a 11,000 lb goose trailer and then did it again with the blue one towing a 7,000 lb box trailer when comparing it to the gas version. and the numbers didn't quite make sense to me. The Yellow towing 11,000 I think did it in like 8 something and the blue one towing 7,000 did it in 10 something. Is it due to the wind resistance on the box trailer even though its 4,000 less in weight? Reason I'm really curious is because I was very surprised to see the smaller trailer get less mpg and a slower time. If you could shed some light that would be great thanks. As a diesel fan I'm scratching my head as to why the Diesel got beat by the gas truck as well. Does that 7th speed in the gas truck really make that much difference or maybe your blue diesel has some issues considering that the yellow one pulled 11,000 lbs up the Ike almost 2 seconds faster with better mpg?

[@duncdunc76]

My bad I miss heard the trailer weights I thought the box trailer was loaded with 7000 for Ike but it was 10000 something. Much closer to the goose trailers 11000 and I suppose with wind resistance it would make them pretty equal if not make the box trailer harder to tow depending on wind conditions. So wild that the gas truck bests the Diesel in power as it seams.

[@zacweggeland675]

Looks like there's a good reason Ram passed on that 5.0 Cummins when they were offered it. That mileage difference is so small it make no sense. Hopefully the tuners will be able to wake up that motor, I'm sure it has a hell of a lot more in it. You could get a 3/4 ton diesel and get better mileage, better towing, and better resale for around the same market purchase price. Or if you're not towing as much get the Ram 1500 diesel and get 28mpg unloaded and 14-15mpg towing 7k.

[@stuhayes2010]

I appreciate their testing. My question is: which one towa better? My 150 (2.7 eco) can tow 7600, but my 6,000lb camper pushes that truck all over the highway. Does the titan have the rear end to safely tow 7,000lbs?

[@edwardtaylor2148]

Yes

[@06RedfireGT]

Love the channel guys. One test I would like to see you guys do is like a 50-70 or a 40-60 acceleration test when towing to compare the truck's passing power.

[@robgrune3284]

another topic...fuel. IF consumers increase demand for diesel trucks, obviously more diesel fuel will be consumed [duh]. What the average Joe forgets is this: every barrel of crude oil yields about 25% diesel and 50% gasoline. Thus, more diesel demanded will have 2 consequences. The price of diesel will rise, due to scarcity. The price of gas will decrease, due to over supply. For every gallon of diesel produced, along with it must be 2 gallons of gasoline. Food for thought ?

[@alacey82]

The common misconception by non diesel owners is that you get the added up front cost of a diesel back in fuel mileage. This is false and I am not sure why it was even brought it up in this video. You get most of that money back either though vehicle longevity or resale/trade-in value. A diesel almost always has a higher reseal/trade-in value from it's gas counterpart especially after 100k miles.

[@larry8065]

Longevity has been lost with emissions control systems and ULSD. As for what you're saying about resale value, that doesn't ultimately save you money. What is the total cost of owning and operating the vehicle? Will you still see a savings when a high pressure pump fails? What about a turbocharger? What if your SCR system fails? Everything on modern diesels is far more complicated and for more expensive to fix.

[@alacey82]

Google "Cummins Million Mile club" and you will see 6.7L engines(all 6.7Ls had emissions equipment) in that high mileage club so saying that a diesel will not last as long as a gas engine is a false one. Also, studies had shown that even modern diesel total cost of ownership is less in most cases when you take in account depreciation, fuel costs, repairs, taxes, and maintenance which you can read here---> www.umtri.umich.edu/sites/default/files/UMTRI.TCO_.Final_.Report.06.24.13.Final_.pdf . Looking at the study you will find that most diesels actually cost less even as little as three years. Not only that, but you are getting considerably more pulling power in the case of the 3/4 and 1 ton truck over the gasser version. So where is your study accounting for depreciation backing up your claims?

[@eugenem5244]

Yes, that study was conducted by the University of Michigan Transportation Research Institute for the Robert Bosch Corporation. LOL! Bosch Corp., one of the biggest producers of diesel fuel systems on earth! You don't think that study was a little bit biased? If not, do you also think all those studies funded by Philip Morris showing smoking to not be harmful are also unbiased? Give me a break... I bet you work for Volkswagen or Cummins or something.

[@alacey82]

Actually, if you knew much about the automotive world, then you would know that Bosch doesn't just make parts for diesels. If you look passed your baseless bias then you will realize they make many parts for gasoline engines such as fuel pumps, fuel injectors, sensors, and spark plugs. In fat, Bosch is one of the biggest spark plug makers in the world. So to say that Bosch is only biased towards diesels is grossly ignorant. Also, if you think the study was biased just because it proves your theory wrong then please by all means tell me how the study was wrong backed up by your proof to refute it.

[@eugenem5244]

alacey82 Doesn't matter,Bosch has to be way more aggressive in promoting their latest diesel technology if they want to make money on it, even if it means promoting it over their gasoline technology. Bosch, and really, the entire German auto industry has more skin into diesel than other nation's auto industries, probably way more than they should. Why do you think light car diesels in North American are sold by German brands. Why are they so desperate to sell diesels, they CHEAT emissions regulators??? Besides this, companies that sell vehicles in the EU are foreseeing a decline in diesel sales across Europe. In fact, some nations are debating a complete or partial ban of diesel sales in light cars. If that happens, they'll need to sell their diesel stuff somewhere else, which probably explains why they keep pushing for more diesels in markets that haven't been full tapped, markets like the US.

[@bubba99009]

The titan diesel seems really underpowered for some reason in comparison with the published specs. Probably why the mileage diff isn't that great. Might be good without all the EPA garbage though.

[@chrisbaker2903]

Where that 1 mpg difference comes into play is really in range per tank. If you've got 35 gallons that's 30 extra miles you can go without worry. You still might run out of fuel or not if you tend to push the limits. I have to say though that you drive to fast. Yes I know what the speed limits are but towing is better done slower. Plus you need a much longer loop and you need some hills thrown in there. I have a 2001 Dodge 3500, 5.9 Cummins inline 6, 6 speed manual transmission, 3.73 gears, dually extended cab. I towed a 30' toyhauler about 8,000 lbs 4900 miles and averaged 12.5 mpg driving between 55 and 60 mph the entire distance. Oddly enough, I got exactly the same mileage towing the same trailer on the same loop with a 94 ford 7.3 Powerstroke with 5 speed manual, crew cab F350, 4.10 gears same speeds. I've tested my Dodge at different speeds. Driving unladen at 75 I got 16.7, at 70 = 17, 65=19.5, 55 = 22.5 and 45=27. You just can't get around the barn door aerodynamic drag factor. Those tests except for the last one were on a loop from the Antelope Valley in CA to the Northwest corner of Arizona and back. I did the 45 mph test around Lancaster, Rosamond, Mojave etc driving exactly as I normally would except for the top speed. Man was it boring.

[@erikkovacs3097]

17mpg gas vs 19.5mpg diesel 14.7% better unladden. 9.6mpg gas vs 10.7mpg diesel 11.5% better towing. Very surprising! Usually gas vs diesel shootouts end up with a minimum of 20% difference climbing to 50% while towing. Nissan must have a very efficient gasoline engine and or a very inefficient Cummins V8.

[@workingcountry1776]

I wonder how this would differ with flat bed or v-nose trailer. Not many people haul flat front trailers. They murder MPGs of even mighty 6.7L disels in Super Duty trucks.

[@rotaryperfection]

The Fast Lane Truck, you guys have the Ecodiesel towing video coming anytime soon? That's the one I've been really waiting for. I remember y'all doing the empty MPG with the Red truck that came with no hitch.

[@abelgomez2726]

From a titan diesel driver when i use cruise control i get 18mpg but when i change over to manual and keep my foot lightly on pedal i get 22mpg on highway at 70 mph. And on streets i get 18mpg by keeping the foot light and im not crawling either i keep a constant speed of 40-42mph on the streets. Cruise control robs you of mpg because the system pushes the break on the downhill instead of taking advantage of the acceleration

[@Slednex700]

Dpf delete n tune would widen that difference. That's so low! My old lb7 gets 16 haulin 8k

[@marathonbaker]

Gas/Diesel Colorado's have the same problem. Diesel option too expensive to be worth the upgrade.

[@wobinga7]

They also only allow you to get it on the higher trim levels with a crew cab on the GMC Canyon.

[@jonmario3440]

at 0:55 Did somebody keyed that truck?

[@douglas685]

Wow. The V8 did great. I'm really starting to like the idea of a Titan V8 XD. You can find the base S crew cabs with 4x4 in the low 30's, that's pretty good value and that V8 isn't extremely thirsty despite being such a big truck. No nonsense truck plus Japanese reliability without crazy pricing.. the base interior is pretty nice too. Add some aftermarket heated leather seats and it's possible to get quite a nice HD truck for mid 30k's

[@workingcountry1776]

Mileage # iin the single digits is nearly a given with a flat front trailer. I'm pretty impressed with the gas engine. 400# torque helps that gasser

[@UltraSS-nj8kd]

nice video. but also diesel is higher per gallon than gas not just for the truck itself plus the DEF adds to the cost. i was shocked though thought the cummings would have gotten better than that though

[@lukman8400]

Great review! I had XD diesel first but my mostly unloaded/suburban driving didnt bode well with the emission components. Loved the truck but sold it. Then decided to move to gasser XD! Love it! Strong and competent when working, smooth during road trips, and elegant and civil enough to get groceries. :) Pro4x is the best trim.

[@Tren_Rides]

Which did you enjoy more?

[@lukman8400]

@@Tren_Rides definitely 2021 XD pro4x. It is smoother, has more payload because gas engine is lighter. I drive it everyday. Diesel shifted hard (normal) and during regen it smelled like diesel. I hated taking it to short trips because i knew i would get there before it warms up and would clog the filter or not finish regen. Just too much worries with diesels. I know some people remove the emissions but it wasnt for me. Both tow well.

[@rodneyhowell2703]

Wow,that gets better mileage than my dodge dually.i am looking at the 1/2ton xd.thanks guys.

[@moulin680]

Great job guys !! thanks for doing it a 70 mph. 👍

[@TFLnow]

You are welcome.

[@SurelyYewJest]

I think Nissan has a bit of a problem here, based on these results. I'm really surprised this diesel is not performing better on MPG than this, and it puts credence behind the rumors that FCA rejected this engine because it wasn't up to snuff. Maybe I'm crazy but it seems like the Big 3 diesels - in 2500 guise - would be in the teens on MPG on this same MPG loop. Even the Colorado/Canyon Duramax, which could probably tow this load, might get better mileage on this loop. And I know some EcoDiesel owners will say theirs could do better, even if it has less power. The Super Ike will have to suss out just how much the diesel helps in this truck over the gas, towing the same load. But based on this, I think I'd get the gas V8 all day long and save the money. on the engine upgrade and the variability in fuel price.

[@mrperfecto2758]

Diesel is better no matter what, they should try these trucks in a big hill with the 5000 pounds trailer and let's see wich engine is better, this is not just about better mpg and if you never own a good diesel engine pick up please do not comment

[@MiguelGonzalez-ok9jt]

Great video guys! I'm enjoying the videos. You guys provide great information!

[@robevans3980]

I think by now we know the diesel variant of this truck isn't 'way better' than the gas in any objective way. But what do they FEEL like to drive empty and loaded compared to the gasoline version? That's the big question.

[@TFLtruck]

+Rob Evans we spoke about this. The two trucks feel about the same on the highway. They are comfortable and relatively quiet. They are also very stable at speed.

[@robevans3980]

+The Fast Lane Truck - How does the acceleration feel under your right foot? Loaded and unloaded I would imagine the gasoline version takes more pedal travel to get moving, no? Great video, you guys are killing it.

[@Josh-nt3fo]

Though I haven't driven either of these trucks, as some who has driven many gas and comparable diesels, I would almost certainly say the gas engine will feel livelier. Gas engines are lighter weight, free revving and make more horsepower., while diesels will have less power elasticity, and because they use turbochargers to make their power, the diesel will be laggier/have more dull throttle response. The diesel certainly has more torque on paper, but it will be the gas engine that will feel quicker and more responsive, even when under light-moderate loads. Under heavier loads, that is where the diesel's torque wins out, I'm sure.

[@NismoSupra]

XD needs a 7spd or 8spd Auto. I considered it breifly but went with the Gas.

[@blakliffy]

i enjoy these vids a ton -16 f150 owner

[@Bunkysworkshop]

What truck would you pick if it was between the Toyota Tundra or the Nissan Titan both with gas engines and why?

[@redneck47441]

I'd like to know as well. Physical appearance goes to Tundra and also a history of reliability. Modernized and appearing to be heavier duty judging by looking underneath goes to Nissan. Love the sound system and Led lights, also bed space with the Nissan.

[@Bunkysworkshop]

+Travis Mathis I agree with you 100%. I want the tundra but the Nissan is right there with so many things as well.

[@redneck47441]

+craigsclocks one weak point I've seen is the older Titans did not seem to hold value at all but reliability I believe is close to that of Toyota. More than 75% of people suggest Nissan missed the mark on this truck and it's not worth it. Which is something you need to consider the publics opinion somewhat because it sways resale. While resale is not as much an issue if you plan to keep for a long period it could still mean a couple thousand dollars in 10 years when replacing.

[@danielk0106]

One thing you have to calculate whether you like it or not and that's the fact you still have to put DEF in the diesel truck so you're spending even more money.

[@andyalaniz5843]

what stage of regen is a big factor on mpgs with these new diesel motor. especially if it is driven alot in the city.

[@s.centralkeystone558]

Great video guys! Not sure there's any reason to buy the diesel unless you really must have a diesel.

[@azphilip1960]

Excellent review! Keep up the great work with the great comparisons! Thanks guys!

[@warrenstemphly5756]

I had a 2002 Chevy 2500HD Duramax, with the rare and elusive manual 6 and usually got 24 mpg commuting freeway.

[@Funky4me21]

I almost liked the 2016 Titan XD, Platinum reserve I bought until last week as I rolled over 23 thousand miles. I got a check engine light.. took it to dealers and they want $4000 to replace the SCR. It just failed to do its job.. Not covered under the Nissan Warranty or the Easy Care Nissan Extended Warranty.. Now I hate the truck.. it is nothing now but a big red spot parked on my driveway. Afraid to drive it and get stuck in Limp mode somewhere and have to have it towed and my butt taxied back home... I live a distance from the nearest city... It has also left me stranded once 18 months ago on a 105 degree day on side of highway on a holiday with 3 young Grandkids and an very angry wife..

[@jasonstokley7274]

Time to go for a DPF delete.

[@lukman8400]

That sucks. I’d go gas XD (the new tranny is great). Alternatively, as the earlier commenter mentioned - delete the emission components. OR, buy a gently used SCR (on XD forum) - WAY less than $4k. Those who delete are selling the takeoffs.

[@mh448121]

I would like to see the 2017 Nissan Titan light duty / half ton mpg rating when towing 7,000 pounds like these Titan XD When the light duty comes out of course !

[@mh448121]

Vs empty too

[@TFLnow]

OK. We will get it done over within the next couple of months (when we get our hands on the 2017 Titan 1500).

[@chadsteele1]

When are you guys getting a half ton, tow drive etc.

[@seanfenwick]

That is shocking! Loaded and towing 3500kg and carrying a 1000kg payload we average 17.4mpg us in our diesel trucks. We don't use petrol in South Africa due to high altitude. Unloaded most of them average 21+mpg in daily use.

[@thelongdaysofwheeling124]

Nice video guys. Would LOVE to see the Titan Diesel compared to the Ram 3.0 Ecodiesel for economy and overall impressions. I've been leaning towards a Ram 1500 Ecodiesel for a while now but have been waiting to see how the Titan Diesel pans out for towing/economy. So far, I see no reason to buy the Titan Diesel at all.

[@crazyhass84]

i agree. i like the effort nissan has put in but i still think they missed the mark! only 1mpg better when towing!!! thats ridiculous! Unless someone is towing 12k lbs all the time which is too much for the eco diesel the nissan diesel is not worth it. nissan weighs 7700 lbs which is the same weight as a 3/4 ton ram... so even with the smaller 5.0l it doesn't do much better than a hd diesel truck. just not worth 5k more in this truck segment

[@crazyhass84]

[@crazyhass84]

+Andy Hass that why ram has nailed it! most half ton owners pull around 7k like in this test. yes the nissan gas pulled it nicely but so could the ram eco diesel and get 30% better mpg. u dont need a 7700 lb truck to pull 7k lbs.... 5900lb eco diesel is the choice!

[@mauricemotors8207]

On paper the XD should destroy the ecodiesel in towing.

[@crazyhass84]

+Revv match1996 in what regard? your comment has no details... are u drag racing a truck? if u are only towing 7k lbs the eco diesel has plenty of power and gets significantly better mpg!! so how would the xd out perform it?!? ed has an 8 spd xd only a 6 speed tranny. makes a huge diff also

[@phprofYT]

I'd like to see that extended to 400-1000 miles.

[@TheCarCrazyGuy]

There seems to be only a 10% difference between the two. Depends what your doing with your truck. I would rather step up to a true heavy duty if I needed the added capabilities.

[@scottlarson2865]

You'd have to step up to a true heavy duty if you needed the extra capacity of a heavy duty.

[@john351stang]

i like to see you guys do a 5.0 ford against a 3.5 turbo ford

[@cwg1998]

The diesel will last longer and the transmission in the diesel is better for towing the gas transmission will wear out fast Imo the diesel is all around better

[@acdcpsp3572]

Not with all the emissions junk.

[@chrisbaker2903]

You're right about that emissions crap. I think the diesels are about where gas engine vehicles were emissions wise in 1975. The technology just isn't mature yet.

[@TheAjmorello]

What kind of RPMs were you seeing with the gas/7sp towing the trailer? Was the truck holding 1 gear or hunting back/forth at all?

[@marcotony15]

What are the full specs again for both. Is the diesel 4x4? I don't know if the 4x4 would be any different on the mileage Would the 4x4 take a lot of maintenance?

[@joenissan]

Considering the extra initial cost of the diesel along with the higher diesel fuel price, the gas V8 is far more efficient.

[@MattSchmader]

Great review guy👍🏻 a little information such as the price of oil change and how much DEF the truck uses would really be handy for long term truck buyers.

[@azphilip1960]

Great video! Great work guys!

[@stevensanchez330]

What mic do u guys use and what's that. Little white camera called

[@TFLtruck]

Sony Action Cam

[@stevensanchez330]

+The Fast Lane Truck thank u

[@alacey82]

Can you guys start posting the trucks specs in the video description or posted in the video? Things such as rear gear ratio would be good to know since most trucks have multiple rear gear options and it can make a big difference in tow performance and fuel mileage.

[@Subarubruce]

Your top off method is not that accurate considering diesel foams a lot when you pump 20+ gallons

[@noearciniegas9426]

Did you use premium gas?

[@greenROB281]

Didn't the Ram Cummins 2500 get 24 mpg unloaded?

[@TFLtruck]

+Robert Green That was on a different loop. Shorter distance and slower highway speed. We will try to schedule a Ram Cummins 2500 soon.

[@powerram92]

+The Fast Lane Truck better hurry I heard 2017 is the last year for the Cummins in a ram

[@greenROB281]

+powerram92 what!?!?!?

[@notme3184]

+powerram92 uhmmm no lol dodge doesnt make trucks anymore btw

[@johng4527]

also that truck was 2 wheel drive, and typically comes with 3.42 axle ratio. That test was really too short to be valid anyway. only used 1.7 gallons of fuel, with such a small amount even a tiny 1/10 of a gallon more would reduce the mileage by more than 1 mpg. The auto shut-off on pumps just aren't anywhere near that accurate.

[@MrAngel2U]

perhaps a Ram 1500: hemi vs ecodiesel

[@dieselhog6246]

Are you guys going to do a similar comparison with the 2017 models? Also what is the max tow capacity for both on the 2017??? Thanks guys!

[@genefortney9133]

Well done guys! Excellent test!

[@TFLnow]

Thanks.

[@lizanncat]

What octane did you run on the gas truck?

[@alexsmba]

That's terrible for the 5.0 V8 Cummins. You guys should do the same test with the 3/4 ton diesels. I'm willing to bet you will see better fuel economy.

[@DavesRandomStuff]

You may need to drive the truck many years to recoup the cost of the diesel engine, however think of how much money will be saved maintenance wise with the diesel vs the gas engine.

[@NissanPRO4X]

I have yet to see any of these on the road.

[@MrEdge39]

I love the same manufacturer/model diesel vs. gas comparison. Have you done the same test with any other brands? GM, Ford, Ram? I'd really like to know if that $9,000 uplift for the Duramax is worth the money.

[@greghomestead8366]

The diesel Titan that I just purchased can tow 12000 pounds while the gas one I looked at the same day tow 9400 that's a little more than a 1000 pounds difference towing as this video stated.

[@Began2011]

And if not a dually and they just want to be different make a special rim and tire setup for themselves. Like some trucking companies use super singles on there drive axles versus duals

[@MrBIGG360]

i agree with alacey82, be great if you guys could post the specs for the veichles

[@TFLtruck]

+MrBIGG360 Which specs interest you the most?

[@MrBIGG360]

+The Fast Lane Truck Just the general stuff, what mpg the manufacturer says it does. Gear ratio, i did notice they said a gear ratio in the video, but would be super easy for us viewers to see a photo that would show the specs side by sidefor the trucs,if its 4x4 or 4x2 etc. Does that makes sense. Thanks TFL

[@philtripe]

do a side by side split screen showing tq hp curb weight gvwr...BRAKING DISTANCES, unloaded and loaded would be awesome...any stats you can find for both trucks

[@andyharman3022]

The diesel wins on fuel economy, 12% better towing, and 15% better running free. But the diesel option costs $5000 more than the gas engine, so the diesel will never pay for itself as long as diesel fuel costs more than 15% more than gasoline.

[@cub8314]

One remember, diesel fuel foams, and also I don't understand why you just don't keep filling til its at the main top of the filler neck

[@scottlarson2865]

So the 5.0 Cummins gets 10% better mpg, but diesel fuel costs 15-20% more. Also, the diesel will probably cost a little more to maintain, which makes the payoff point for the $5000 more expensive diesel about never. These guys tested a Ram 2500 2WD Cummins on this same loop and got almost 25 mpg without the trailer.

[@kvcsoliver]

I did some rough calculations, just for fun. I got approximately 6 million miles to even out the 5k price difference. Based on: only the fuel consumption (not with dpf), diesel: 15 mpg, $2.1/gal gas: 13,5 mpg, $1.9/gal So correct me if I'm wrong, but this is ridiculous. If someone buys the diesel for mileage that is plain stupid.

[@RadicalRitz66]

The ecodiesel gets around 25mpg for 7000lb towing

[@scottlarson2865]

Not while towing the barn door of a trailer they're using. In a similar towing situation to the one in the video, the Ecodiesel will get 11-12 mpg.

[@Weird_1]

You can't really trust the averages until Atleast 500 miles. The computer is still doing a lot of adjusting

[@marshallwebster6435]

What octane gas was used

[@fifthcircle1]

I'm in the market for a new pickup. Toyota fanboy, but I'm very underwhelmed by the current Tundra. Drove a few F150's, and like the ecoboost (speed), and may order a '17. I can't get myself to like the Silverado. Ram seems nice, but ecodiesel is too much $$. Just drove a Titan XD diesel. Loved it! I'm waiting for the light duty now. Press embargo 8/15/16...right? Should be at dealership shortly after.

[@willdiesel3909]

Que cosas, La TITAN DIÉSEL, acá en América latina hubiese tenido un buen nivel de ventas, principalmente en esa época donde el combustible diésel era un 10% menor que la gasolina regular. Me imagino que que ése CUMMINS es un Common Raíl con turbo de geometría variable. Saludos desde estas Honduras.
