2023 Chevy Silverado Baby Diesel VS 5.3L Gas MPG Run: Don't Buy Until You Watch First!!!

Is it me or does no one do gas and diesel comparisons on YouTube. This guy takes you for a ride and both. thank you Sir!🙏🏻

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 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

Need more of these types of reviews. Well Done. Thank you.

Drove 5.3 since 03. Bought a 3.0 duramax in 21. Completely impressed in all aspects. Max torque is achieved at low rpms and at cruising speeds and fuel mileage is beyond expectations for a full size half ton. Fun to drive

I have owned both of these and driven all the options in every truck in this segment, and the 3.0 Duramax 10sp combo is the best of them all imo. The linear powerband just matches this size truck perfectly.

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 had a 2022 Silverado LT with the 3.0 Duramax and I was averaging 34-36 mpg in TX. It was a great truck, I’m getting a Tahoe with that motor. It’s a great motor.

I own a 2021 crewcab 4x4 rst 3.0... I commute 700 miles per week. I fill up once & average 32-34 mpg. I get around 25-26 around town. Low end torque & towing is amazing. I've had no mechanical issues & love my purchase... planning on buying a Tahoe for my wife with the 3.0....

Great video with good information! I have the 3.0 duramax in a GMC Sierra 1500 AT4. It gets incredible fuel mileage, and I love the torque curve. A blast to drive.

I know this isn't apples to apples but I currently have a 2021 2.8 diesel Canyon AT4 with the off-road performance package(skid plates, etc.). With the additional weight, I still get 30 mpg at 75 mph. I've put a little over 5,000 miles on it in the past month with near daily use and it has been fantastic for my use. I think that points to the main issue though, most people don't touch that kind of daily mileage and they never see the benefits of having a diesel which is why all of these companies are killing diesel options in non-commercial vehicles.

Thanks for the content. Went with the 3.0 as well.

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.

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 the 3.0 diesel in my 2022 Sierra AT4 (refreshed). I average between 26-30mpg. My best 50 mile is 33.7 mpg!!! I originally order the 6.2 but last summer they did not have enough 6.2s in stock, so I changed to the 3.0 diesel; best decision!!

Thanks for the fair evaluation.

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.

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 :(

We have a 2023 gmc yukon with the 3.0 and we live in WV where nothing is flat. And we are getting 25-31mpg

I just ordered a 6.2 trail boss. I can’t wait till I get it
