@@morthomer5804 I know that's true. But my local gm dealer here in southern oregon sells most of their diesels to other dealers in....SOCAL !!! When they get a diesel in stock, it doesn't last long on the lot because they all go to cally. Weird but true. When I bought my 2022 diesel Z71 Colorado last year, my salesman got a call from a dealer in socal, and he put him on speaker phone so I could hear him. He tried to talk my salesman out of selling the truck to me, at $3k under msrp. I love my little diesel truck...

[@chadfoust6942]

My friend and I just took a trip and his Z71 Diesel and it got over 30 mpg regularly. That thing got better fuel mileage towing a car on a car hauling trailer than my Jeep does by itself:-) great review! Side note, I would never run 50 psi on the rear tires of an empty half ton. It reduces your contact patch on the road and crowns the tire so you prematurely wear the center of the tire and it rides much harder. I gladly pay the 0.001(whatever) MPG penalty for a smoother ride and better tire wear

I get 25-26mpg on my 3.0 Duramax on regular commuting. Long highway drives I’ve gotten as high as 33.6mpg when keeping it below 65mph. Great engine. Full tank usually gets me about 550-560 miles. I’m happy with the power train.

I live in Utah where he filmed this. I pull cars and boats all over with my 5.3L Silverado with 4.10's. If I'm going up Parley's Summit on I-80 coming out of SLC up to Park City I will have to run it in 2nd gear at high RPM but it gets it done. Anywhere else I have no problems running 75 mph with traffic. Car trailer and car totals 7000 lb and my boat and trailer are around 3500 lbs. If I pulled anything heavier like a huge camper, I'd go with a 2500 or 3500 truck. A turbo diesel would be nice but a gas V8 can pull just fine, you just can't be scared to rev it. If you think you're going to pull 7000 lbs up a steep mountain at 70 mph at 2000 RPM in a gas engine you're misinformed. I pull my boat cross country in the summers.

[@iflex1963]

Purchased a 4wd GMC Elevation a few months ago with 59000 miles....Couldn't be happier so far. I love the low end torque.. barely push the pedal and it pulls hard. Max torque at 1500 rpms. I didn't want to have to rev the engine up to get on the highway. I've watched many KZbin videos of 1320 ft 3.0 vs 6.2. The gas always has to catch the 3.0. as it initially out accelerates the gas engine. Im not worried about speeds over 75 mph so I'll stick with the diesel. Also, there are tunes and after-market turbos to bring up hp and torque significantly for the diesel. I'm averaging 27 mpg and getting over 32 on the highway in a full size 4wd pickup. Thats insane.

[@curtis1951]

That diesel is impressive. I would like to see a long term overall cost comparison because fuel mileage isn't the whole story. The initial cost is higher plus higher maintenance and fuel prices of diesel over time compared to gas.

I have a 2020 3.0 and love it. It gets 25 mpg daily and up to 36 mpg on the highway. Another huge benefit is towing where I consistently get 19 mpg towing a 4500 lb boat. It doesn't really burn through DEF unless you are towing so, while I think it is an annoying thing to add, the cost isn't that high. The oil changes are simple and reasonably cheap doing them myself. It has amazing torque too.

I has a 2017 Silverado 5.3 for a couple years. Mpg was ok. Towing my 4000 lb boat was an issue. It would do it but it didn't like it. And it drank gas! Traded it in on a 2021 Silverado with a 3 liter Duramax. Both trucks were identical LTZ , 4 Wheel drive etc. Color and engine were the only difference. I love this truck! It tows my boat with no issues. Mpg does go down but still beats the 5.3 by a long shot! I can fill up in GA and drive to my mother's house in PA and have fuel left. Not much fuel but it was still there. My best mpg was a couple months ago to the Outer Banks ,NC. I had a best of 42.6 . I have a picture to prove it. Now yes fuel is about $1 more a gallon over gas and you still have DEF to fool with once or twice a year. I fill this bad boy up about once a month of course I am retired and don't drive the work commute everyday. But if I did I would still get it . Hell $995 option and great towing with spectacular mileage. Heck of a deal.

[@uvaldoavila7788]

I have a 1st gen LM2 1500 Duramax Silverado with 30k before a 5.3 Sierra and the only thing that makes this a debate is the spike in diesel prices… pros to the diesel are fuel efficiency, torque, towing, cleaner emissions, typically longevity over gas engines, GM built engine from the ground up with 2019 model release, I think one the the most underrated pros is also the uniqueness of having a 1500 diesel. I remember pulling up to my uncles and blowing his mind bc he never thought in a million years they were going to bring back 1500 diesels. Cons are DEF, oil belt maintenance @ 150k, repair cost down the road, these diesels aren’t drag racers by any means but are peppy nevertheless. All things considered diesel still takes the win IMO.

If I was buying a new Silverado I'd definitely be getting a diesel. I drive a 2018 diesel Equinox AWD and I love it. In city I average about 35 mpg and on the highway about 50 mpg. You can't even approach that with a gas engine.

[@l13712]

Thanks. I switched from a 5.3 Denali to an EcoDiesel a year ago. I couldn't find a 3.0 Duramax I could afford so I went with the Ram. My experience with the mileage is exactly as JB reports. Diesel's get their best milage when they are warm and cruising. I'm not convinced it does better when running errands in the winter. The wild card is the price of diesel. When I made my switch I did a deep dive and determined that as long as diesel is no more than $0.60 greater in price than regular unleaded I'm coming out ahead compared to the 5.3. Problem is, here in the PNW diesel is as much as $1.20 more :(

I have a 2022 Diesel Escalade 3.0 Sport Platinum 4x4. I simply LOVE IT!!! Before that I had several gassers. The 3.0 is insanely reliable and has incredible power mates with the 10 speed transmission. GM blew it out of the park with the 3.0 and 10 speed combo. The low end grunt is insane. I grew to love it so much that I purchased a 2022 GMC Sierra Denali Ultimate 4x4 for myself and gave the Escalade to my wife. We both get over 32+ on the Hwy and approx 26 average city/Hwy. I can’t explain how much I love this engine. Just test drive one please. You will know what I’m talking about. I have 27K miles in my Escalade with only one issue. A crack in the intake manifold. It was repaired in a day at the dealer and it’s been fine ever since. Service engine light was the only issue we noticed. The Sierra has approx 10k miles. Zero problems. Top end is a little light. But the trade off in economy and low end grunt makes the Diesel the only way to go. You would have to be crazy to buy the gasser. I’m sorry but it’s true. My $0.02

In my area of Texas, fuel prices have turned in favor of Diesel - that was not the case just a couple of weeks ago. Comparing fuel cost only for the 5.3L (regular), 6.2L (premium), 3.0L Diesel for a 4x4 Tahoe, diesel is about $550-$600 a year lower if you drive 12K miles. Add in $100 extra for the higher cost of 2 oil changes, DEF and you are still about $300+ lower in annual fuel, oil, and DEF cost. I love the Diesel for its towing capability while giving much better mpg. Still seeing issues with 5.3L and 6.2L lifters and push rods - which will not be corrected ever, given GM is now investing in the new generation small block v8.

Everyone talks about the added MPG with the diesel and how it's saving them money, but the OVERALL operating cost is significantly higher with the diesel compared to the 5.3 gasser making the added MPG of the diesel a complete wash. The main thing is (in my area) diesel fuel cost more than $1.00 per gal more than gas. That being said, the diesel costs roughly $40.00 more to fill up than the 5.3. If you really crunch the numbers, that puts the diesel behind the gasser right there for operating costs per mile even though the diesel does actually get better mpg. Then add in def fluid and all the other maintenance costs that are much higher for the diesel compared to the 5.3, and it's easy to see the 5.3 is easily the cheaper way to go.

[@brucemoorejr3115]

Wrong. I pay .20 cents additional for diesal . The last 5.3 I had a few years ago would not get any where close to 20mpg its average was 14-15 MPG and forget towing snything you would be in the single digits. as far as Maintenance thats not true about the diesal see from my previous post. The fuel filters do not need replacing very often,I take mine to the dealer for all service work and after three oil changes the fuel filter life is still at 53% at 17,000 Miles. The DEF consumption is another Non issue at in 17,000 miles i have used 4- 2.5 gallons of DEF in this truck ,so in other words it uses one bottle of DEF per 4500 miles and Finally i average 27-30 MPG around town and always get 34 or better on the interstate. Towing wise i usually get around 24 MPG or a hair better towing a 16' trailor at around 5000 pounds. There is not a gas Motor that can touch it mileage or power wise. Add in the Lifter problems on the 5.3 and 6.2 (just do a search) the gas motors are junk and have been for a while I'll stick to the Diesal motor.

That said I can't really put a finger on it other than it just drives better than my 2 previous 5.3 V8's. Where I live it was -31 on the weekend, with the block heater plugged in for 4 hours I died right up, rough idle for a few minutes then smooth. Today I pulled a 6 x 10 trailer with about 30 bales of hay, not a heavy load but it drove like I wasn't even pulling a trailer. Best of all I have gone about 170 kms and my range still says over 600 kms. That's with winter blend diesel, and in auto and a bit of idling. When my sales guy went over everything it sat idling for maybe 30 min plus a bit on the weekend. Probably the best powertrain I have ever driven.

[@Kanakid]

I’ve had several diesel 1/2 tons. Love em. However the fuel price difference between gas and diesel comes into play which just about eliminates the mileage savings. Then you add the DEF and a more expensive oil change and there’s no cost savings to drive a diesel. Once they are off warranty and you have some engine problems the diesel will cost you much more than gas. I now drive gas engine pickups.

[@joshualake4882]

I think it's about how often you drive. I just priced DEF fluid, about $50 for 5 gallons here, oil and filter probably close to $90-$100. I,myself, average about 6500 miles a year driving so 1 oil change a year. Things can change but for now that's where I'm at. Diesel here is .20-.30 more than gas. My 2018 5.3 sees 15 city and 20 highway. If I were to get a new truck I'd want the 3.0 because I spend way more now at the gas station than I do with oil changes and maintenance. My last oil change was $80 from my local shop.

[@james9810]

@Kanakid, You are correct. Just watched this video on 11/28/23 and the price of gas in Dallas,TX is 2.57/gal, diesel is $3.33/gal. So doing the math with his results are as follows: Gas - $2.57÷18.7mpg=13.7 cents/mile Diesel -$3.33÷24.3mpg=13.7 cents/mile So the diesel does deliver better fuel mileage, 5.6 mpg more than gas, a 30% increase. But the cost of diesel fuel negates the advantage.

Great video. I like diesel. I have been looking at the 3.0 Duramax. The only thing that gives me pause is the wet Kevlar reinforced oil pump belt. Depending on year that is rated to 150k - 200k miles (or equivalent hours). That belt needs to be replaced at that service interval and that means removing trans, or a visit to dealership or shop for a costly maintenance. To be fair though, any engine is going to need costly service at some point. The only reason I don't have a diesel yet is that I believed the maintenance would be more than gas. However, the efficiency difference between gas and diesel probably makes up for that.

[@matthewanderson9912]

Nice review. If I ever went back to a 1500 I would 1000% without question get the 3.0 diesel even with fuel prices what they are. And I’d just take my chances with the emissions nonsense. I’m not touching a DFM engine, and both the 5.3 and 6.2 are that. The fact that you can get full size car mpg with a full size 4WD truck is just incredible. And the Trail Boss is the worst example for fuel mileage because of the 2” lift. They are epa rated less than a non Trail Boss.

2 things - the service bulletin that cjrod9443 mentioned states that normal oil consumption is 1quart/1000 miles while working the engine(towing) and 1 quart/2000 miles while being light footed. That is terrible in my book. Second thing - its cool to see those MPG numbers, 30% better MPG with diesel, but the diesel also costs at least 30% more per gallon in my area so cost/mile is a wash for fuel. Now add cost of oil consumed and DEF costs and gas is really a cheaper alternative.

My only issue is the seats in GM trucks compared to Ram aren't as comfortable for me and I have a hard time sitting in them for a while. I miss the old seats I had in my 03 Z71. I too wish people had a better understanding of diesels in the US as they are better all the way around in my opinion, but people are lazy and won't keep up on the extra maintenance compared to a gas. Also, just to mention it, Germany did a study over 25 years and came to the conclusion that overall, a diesel has less of a carbon footprint for the life of the vehicle compared to an EV from production to junkyard.

Nice demo snd great enthusiasm. Here is the reason they will choose the gasser over the smoker. 1. Lower buy in. 2. At 18 mpg vs 23 MPG, it will cost just a bit more in fuel per year based on 18,000 miles driven for each truck for the smoke maker. That's using assumptions of those over all mileage you got. It will be significantly lower over time for both. I am using gas and diesel cost where I live. It was almost 5.00 per gallon recently. But now 3.00 for Gass and 4.00 for deisel. The reason in favor of the diesel will be towing machismo and the turbo diesel vibe. Depends on the real world application and prolly why they offer the option. The diesel will prolly be cheaper for engine work and last a little longer, but 10 to 15 grand more worth? Hmm
