[@dedalliance1]

@@bryanhersman4037 I mean, 1,350 pounds of payload minus the 650 for tongue weight on the 6,500 pound trailer leaves you 700 pounds of payload. 2 adults at 175 pounds a piece is 350 pounds, 3-4 small kids at 100 pounds or less and you're right on target. Going over a hundred pounds or 200 pounds really isn't going to matter. I'd say the numbers work out pretty good, and also remembering this is on a fully loaded unit, on a less loaded one you'll probably gain a couple hundred pounds of payload. The problem with a Silverado is you only have 5 seats, maybe 6 if you get a bench in the front but it's not very comfortable. Most people don't have a family of 8, but a lot of people have 3-4 kids but cramping them all in the back seat of a truck isn't that much fun on a long road trip. With this Tahoe everyone can get a window seat and not sit in the middle, if there's only 3 kids someone can sleep in the 3rd row, you can get 2 TV's in them, and you have a trunk for a suitcase that's secured and isn't an open truck bed. Plus, for the 98% of the other driving it won't be towing and you can seat 8 people in it and use it to go get groceries and what not without it being a truck.

Thank you for letting us here it idle!

[@exparrot9074]

Andre, my guess is you had an issue with foaming on the top off after the towing loop as the trip computer first under estimated fuel economy on the tow loop, then over estimated on the highway loop. If we look at the additional fuel that should have gone in after the tow loop based on the trip computer, it comes out to 0.2 gallons. Subtract 0.2 from the fill up after the empty run and it works out to 30.3 mpg empty, much closer to the trip computer. I think with the diesel vehicles you need longer mpg loops to take into account errors due to fuel foaming on fill up.

[@The_Osprey]

Also they do regens where more fuel is dumped to burn out the particulate filter. If not for emissions bullshit diesels would provide even better MPG.

I crafted a "V-nose" mod for the trailer and lowered my speed to 65 and brought the mpg up to 13.3 empty. Aero drag is CRAAAAAZY when you get over 55 with any kind of enclosed trailer.

The good thing about Tahoes (and Suburbans) is GM sold a ton of them making repair parts reasonably priced and plentiful many years later. But these new ones are so costly that GM isn't going to sell that many of them, especially the diesels, so it is going to be hard to get parts to keep them up with all the fallible features (like adaptive cruise) that have been added.

[@JayTdub13]

I wish Toyota would do a diesel. GM is smart for bringing it back.

[@MrJcjet]

They make lots of them. they just don't sell them in the United States unfortunately. They are not clean enough for our emissions standards. Toyota said a few years ago that it would cost approximately $8,000 per vehicle more in sale price to justify a diesel engine emissions setup. And that for almost any driver, the extra cost could not be justified in fuel savings. Supposedly the new tundra hybrid will get very close to 30 mpg. if that's the case and it's also more powerful and cheaper than the diesel option, I think that will be a winner. I love the idea of this new GM inline six diesel, but it has some very poor internal engineering. The oil pump is mounted on the back of the engine and uses a belt to drive it. And that belt has to be replaced at about 100,000 mi. The way that they designed that system requires the engine to be removed in order to do the belt swap because you have to separate the transmission from the engine to remove or install the belt. I cannot figure out why you would design such a stupid system. But what that means is these GM diesels are going to require about a $3,000 belt change at 100,000 mi. That's just stupid.

I had it paid off and when I traded in for my new GMC Sierra Denali HD with the Duramax it was nice to have such a big chunk of that new loan paid off from my trade value.

[@WinningDeadlyEncounters]

@@OneNationUnderGod. I am not 100 percent on the trade in value argument. I have owned diesels two of last three trucks You get more for trade in but we are paying 10k more when we buy them. I bought my 17 ram for 64000 traded it in in 18 for 49. If we keep them 5 years math works better. But we are only getting the money we paid back. But if we need them we need them i agree with that. I tow a 8500 lb travel trailer prob 8 weekends a summer i tow a tractor and skid steer prob 2 times a month rest is snow mobiles quads dump trailer. Diesel does it better for sure.

Makes you wonder of the difference in particulates in exhaust compared to gas. Perhaps it's worse but when you factor in better mpg is it still as bad for distance traveled?

[@dzelpwr]

Modern diesels since 2007 have emitted LESS particulates than gas engines thanks to the advent and mandate of diesel particulate filters in the exhaust. It's NOx that diesels struggle with most. NOx is what VW was found cheating back in 2015. At the same time the regulations from 2009 required NOx levels 10 times lower than early to mid 2000s regulations... Ever since the cheating scandal, diesels have had to go through an impossible to cheat on-road emissions analysis test by CARB and EPA to obtain certification. So rest assured, any diesel after that scandal left the factory being a properly squeaky clean diesel.

My Jeep Patriot with a little 4 banger only averages around 22mpg with a mix of city/highway driving.

They do offer these in the low end trim package now. There is even a KZbin channel owner that has one and has made about 5 or 6 vids on it so far. His has cloth seats and it's an LS. At 70 mph he's getting about 33mpg.

Who spends $79,000 that is worried about gas mileage? Seems like any savings you get from the mileage are already lost on initial purchase price, and knowing GM it'll have a lot of problems (electronics and otherwise). I can't believe anyone thinks vehicles like this are worth that kinds of money....

[@TheDaltonmichaels]

According to the build and price tool when i go to it you can have the 3 litre diesel on every single trim level. maybe it updated since the video? Maybe the build and price tool is not an accurate representation of what dealers are actually allowed to order? im custom ordering a new truck in about a week and my dealer told me i had to wait do to production constraints, they couldn't get my package built due to the options i selected not being available until a certain date.

@@kgb5351 either there is something wrong with all of those trucks or that is strictly in town, low speed and a lot of idling to get that low of mileage. Most of my towing was light city and highway.

Here in 🇵🇷 Puerto Rico diesel fuel is cheaper than gasoline, and 90% of our stations do not have ethanol in their Gasoline which is nice.

I have a 2021 GMC Denali with the 3.0 duramax. I love my truck all around especially since I’m averaging 28-29 City and 35-36mpg on the highway with it. I have about 5900 miles on it. The main problem with my truck is that, it has done a long crank no start four times in the eight months that I’ve owned it. Apparently this is happening to the 2019-2021 models so this has been going on long enough for GMC to do a recall on these. I also have researched where it could take 50 hours to fix and by lifting the entire cab off of the vehicle. I really hope that TFL looks into this to see what can be done? Thanks.

WHY is there not a diesel hybrid out there? That sounds like both an MPG and performance marriage made in heaven. Also, why do you not use the actual odometer mileage when calculating against the fuel used? I'm curious. Also, do you do cost comparisons? Diesel is often quite a bit more expensive than regular gasoline.

Toyota do have 2.4 litre & 2.8 litre D-4D turbo diesel and 3.3 litre twin turbo V6 diesel as well a 4.5 litre twin turbo V8 D-4D. But I doubt they're gonna be used for the North American market because of unfavorable regulations for diesel passenger vehicles.

wish gm would offer the 3.0 in basic work trucks for the 1500

[@IKhanNot]

The fuel economy is great but it will take some time and a lot of driving to mitigate the extra price the diesel costs to both purchase and maintain. The unfortunate thing with newer diesels are the DEF, DPF and EGR systems which are very failure prone in them. Add in having to drive longer so the emission system can regen plus didn't a GM engineer say that the engine's timing chain which is in the back and the oil pump is driven by a wet belt that requires replacement but of course the transmission needs to come out... Yeah just get the 5.3 or 6.2 because at least the DFI issues are easily sorted with a carbon cleaning.

[@courtneyanderson2293]

Extra price? There is no difference in cost between the 3.0 and 6.2. I have 2 Yukon XLs with the 6.2l and the 3.0 Caddy is coming in the next week or so. I run 60,000+ miles on them in a year and fully expect my fuel bill to drop around $5500 a year. Oil pump belt will probably run 200,000 miles without issue and the moment it fails the dash lights up and you shut it off. I expect to change it once or twice in the next 5-8 years and it will owe me nothing.

[@KoliaMtl]

It would be nice to get an mpg rating at more reasonable speeds. I haul our 30ft / 5,500lb RV going 55-65 mph and get 14-15mpg with a 2018 1500 Silverado with the 5.3l. No way I can justify the extra for a diesel engine.

[@courtneyanderson2293]

@@KoliaMtl do you get 28-30 mpg on the highway? I have 4 yukons, 2 older 5.3 and 2 newer 6.2. The 6.2 are both 20% better on fuel that the 5.3s and I expect the 3.0 duramax one I ordered to be 20-30% better than the 6.2s. I rarely tow with them, but run about 60,000 miles a year with them and 5-8 mpg is a huge savings. Should be approaching 50% better on fuel than my 5.3 yukons so they will likely be sold or just used locally. A 2018 5.3 should be much better on fuel than my 08 and 12 though, so likely not worth upgrading to a diesel or another gas. If you are upgrading, it would be worth looking at the diesel then. At $5-7,000 in fuel savings a year, it's a no brainer for me.

I'm a 1,000 mile round trip to the city and do that 50-60 times a year and I'm currently paying $1.699/liter ($6.42/gallon) with another fuel tax increase coming it will soon be $1.739 ($6.58/gallon).

In the summer (back in Canada) I need to tow a boat (7000Lbs) approx 4 times from May to Sept, although not too far (approx 200 km). Which should I buy?

[@killercan10]

Your empty run proves that the real world #s are going to be better than the EPA numbers, and much closer/almost the same as the Silverado 3.0. That CAFE footprint due to its higher curb weight is one of the reasons its "rated" lower than the Silverado. I was hoping you guys would to a loop that would show this to be the case. Great towing MPG as well it seems. You guys also got 12mpg in the Silverado 3.0 test you did vs. the Ram EcoDiesel further proving it.
