@@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...

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.

[@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

[@kurtbuecheler]

I have a 2023 GMC Sierra AT4 with the LZ0 and I love it. Fast ignition and great MPG in the first 500 miles with the best drive being over 25mpg and I have not yet broken out on a long highway drive. I think the power is more than sufficient and well worth it given the MPG. By the way, requiring seat belts to shift into gear CAN BE TURNED OFF...but it's buried deep in the menus. :-) lol

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.

The diesel was great 0-20 but passing and acceleration from 40+ was like driving an old 4 cylinder car. The 6.2 you could confidently pass and didn’t need to floor it to gain speed, half throttle seemed to be enough to accelerate. I really wanted to love the diesel but after driving the 6.2 just couldn’t. An AT4 with the 6.2 is where it’s at.

Totally agree with your analysis. I have only had my 23 Silverado LT Duramax for a week so definitely haven't had enough driving time to be an expert far from it. 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.

[@gunnerneikoify]

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.

[@January-pc9ll]

Good thing everyone is doing 80.

[@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.

[@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.

[@peltel2222]

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

[@kaivonmortazavi8656]

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.

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 :(

You can change the settings to allow you to shift into drive without your seatbelt.

[@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.

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.

Great video. Thanks. My calculations suggest that the fuel cost driver between the 3.0, 5.3, and the 6.2 is the price of fuel. Diesel and premium running $0.80 and $1.00 per gallon more than regular means the 5.3 wins the fuel cost comparison. About ties the 3.0 and beats the 6.2. That is why my new Silverado has the 5.3.

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.

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.

[@ALMX5DP]

Price per mile it's very similar (using the national fuel cost average, so YMMV). Using both of those figures, the gasser would cost about $18.28 per 100 miles while the babymax costs about $18.85 to go the same distance.

You can actually start the truck and a couple other models and just wait for about 10-15 seconds and then the fasten seatbelt will disappear. I work as a lube tech, first dealership job so I gotta start from the bottom since my experience has been personal wrenching with friends on their cars and my own, at a Chevy/Cadillac dealership and it’s really annoying for us who are just getting in and driving it through the parking lot to get to our bay, so if I’m in a rush I’ll just buckle the seatbelt behind me and leave it buckled until I park it up front when I’m done. Or if I’m not in a rush, I just sit and wait like 10-15 seconds I believe until it shuts off then it’s fine and doesn’t come back until the truck or car restarts. The equinox, traverse, and most Silverado and sierra’s I work on don’t have this thankfully. I see it’s super annoying, I absolutely hate it. DO NOT run your tires at MAX PSI, that is a recipe for disaster. Run the tires at what it says on your door placard. If it’s a trail boss then it’s usually 41, other Silverado’s run 35. COLD. I see a lot of people coming in with WAY over tire pressure and the middle area of the tire is super worn out compared to the outside, and it’s the opposite for underinflation. If you buy these trucks they are always going to have body roll no matter what you do like adding air to the tires, just something you’ll get used to. It’s honestly not even that bad,. Only time you should be running under inflated tires should be off-road, or a LITTLE more pressure when towing. It’s a TRAIL BOSS, the lift will be a little more body roll, and the tires are more of an aggressive tread for off-road usage, so of course you’re going to have a tiny tiny bit more road noise, feel, etc. if that’s something that you don’t want then don’t get those options, get the regular models
