Ditching the Duramax Diesel...back to a GM Gas 6.6 truck?

I am on my way to trade trucks, and I am trading in the 2020 Duramax Diesel 2500 LTZ for a new 2024 truck with the gas 6.6 engine. I cover my reasonings, as well as some information on towing, gas mileage, ownership costs, and others.

I did the same thing in 2021 and havnt looked back once. I’ve loved my 6.6 gas.

Most important thing is do what your gut tells you. I've had both, had issues in the gasser 6.6, broke exhaust manifold bolts 3 times. Last time out of warranty so I traded for the diesel. That being said, they all have there issues, as long as your happy with those issues, that's what's important. Thanks for the video

Made the same decision a year ago. Yes I get 2-3 miles less per gallon towing but I don’t tow every week. Nice to be able to just turn the key, fill up where ever I want and not worry about idle time. Also I do enjoy the sound of the V8 so there’s that. Hope it works out for you too.

I did the same. When the 24 gasser got the 10 speed i jumped on it. I drove a Duramax for 11 years. I love the gasser. Much simpler engine. None of the diesel emissions BS to deal with. Like you mentioned if you actually look at the numbers and do the math. Diesel isn't cheaper. Cost more all around and the emissions systems make it less reliable. My Duramax averaged 14, my gasser averages 12. Gasser is also like 900lbs lighter in the front so it doesn't sink like a rock off pavement.

I have the same fifth wheel trailer as you and used to pull it with a 2016 2500 gasser. On flat land it was fine but on the highways in TN with hills it was a dog. To maintain 70 I would have rev the rpms up to 4-5k and gets crazy loud. Recently bought a 2024 3500 AT4 dmax the towing experience is night and day. Super quiet in the hwy and up and down hills. The gasser got about 6 mpg pulling the camper and a recent trip with dmax was between 10-11 mpg driving 70-75 with hills. Couldn’t be happier for now ;)

Love the Duramax. Never owned one, but the idea is great! I have done the math as have you. Even comparing the 5.3 to the BabyMax, the math is not there. Better MPG with the diesel, yes. $0.50 - $1.0 per gallon more for diesel plus DEF, plus higher maintenance costs = no savings for Duramax vs. gas. The sales Manager at our local dealership talked me out of the HD Duramax I was admiring and back into the 5.3. No regrets. Also enjoy your roll north on I-35 through the Owatonna area. traveled that road dozens of times. Thanks.

I had a 2011 Powerstroke that was a great pulling truck, it was deleted with a tune. I could no longer being in California find a smog guy that could pass it . The amount of stress with the injectors, the turbo, fuel filters, def, egr problems. I was over it! I went and bought a 2024 gmc sierra 2500. It has a higher tow rating, super simple motor! And I have not worries about diesel fuel stations, fuel filters, turbo issues. Glow plugs, I’m super happy with my l8t 6.6 gas! I’ve had a couple recalls which are all under warranty but . Gas makes more sense these days. Especially in California from r me that is.

After you discussed the real-world MPG comparison for your use case, you made the right call. I was surprised to hear only a nominal fuel efficiency difference. The diesel would show its advantage by pulling heavier near its max weight. The after-treatment is choking the diesel while the gas is breathing easier.

[aharonz]

Did the same thing. I’m a diesel fan boy! Always will be. But what I’m not a fan of is the emission garbage on these trucks. Obviously diesel is always gonna have better power and torque. No doubt about it! Sold my Duramax got me a 2025 sierra 3500HD AT4 with a 6.6L gasser. So much more simple than the modern day diesel!

[tscherry]

I just did the same thing. I went from a Ford 6.7 powerstroke to a 6.6L gas. I'm not towing over 20k and I'm tired of all the emission issues, repairs and extra costs of owning a diesel over 12 years.

[fredwilliams]

My l5p has 111k miles zero issues. If you can’t maintained it yourself you don’t deserve to own one. Just facts

[kingrider]

It’s funny to me to see diesel/gas people going to war over something as silly as this. Gas and diesel trucks have both come a long way. It’s a pretty formula really. If you tow heavy then you should go diesel. If your towing your 9, 000 pound camper go gas🤷‍♂️ now if you just want either or do it. The arguments over it are hilarious though lol.

[shannoncasper]

The diesel is way more powerful, but it's also way more expensive. I can do anything I need with the gas motor, and the old school push rod motors are very reliable and last a long time and much more easier on your pocket book.

[arlenboyer-vv]

sold my duramax bought 2024 f350 7.3 with 4.30 gears i never looked back tied of all the diesel stuff and expense very happy with my decision

[mattie]

Appears you just wanted a new truck.
Your good diesel trade in allowed you to get a newer truck with a less costly motor.
I’ll take 2X the torque any day of the week. If $$$ is an issue - trucks with either motor would be a bad choice.

the gasser 6.6 MPG is appalling.. i had the 5.3 2019 chvy and it really impressed me. from towing to around town usually stayed between 17 and 18 mpg.. traded up to a 2024 2500 duramax to ease towing my camper.. tows like a dream

[billylee]

I have both. I drive a 2022 duramax and my son drives the 2022 6.6 gas. I can’t imagine giving my diesel up for a gasser. Oil changes are a few bucks cheaper on the diesel but they equal about the same with the fuel filter. I do like the gasser but it is definitely not in the same ballpark as the diesel

[PatrickAllison-zzgj]

I bought a 22 6.6 gas long bed, had good power 18 mpg highway. Lots of good features . But 2 in slop in the steering, and horrible brakes . It was like the power booster un hooked . The dealer said nothing wrong with steering and the brakes were a new design, i was mad and traded it for a ram . The ram has great brakes, but 1 in of slop in the steering, still less . I wish i had just went to a general manager or something with the chevy . Now the price has raised $ 8 k

[wolfweb]

Im looking for a gas silverado for another reason.. cold winters.. living above the arctic circle in scandinavia and never had a diesel starting as easy or getting warm as fast as a gas truck or car

[marksullivan]

Banks has an excusive patent on a cold air intake for duramax that actually works & really wakes up duramax engines it wont hurt to look at the results
