6.2 or Diesel?

[BobbySC]

Hi all! Another question and posting here since there is such a wealth a knowledge. I have a Lexus GX550 that I really just don't like. Live in Charleston, SC so nice weather almost year around.

I was waiting for the 4WD diesel to come out so I could get a High Country. I do want Supercruise as I drive to Florida, NC, and GA a few times a year from SC and think it would be good for resale (I could be wrong). Seems as of now I cannot get that combo. I have also never had a diesel.

I started looking at the 6.2 again in High Country with Supercruise. Looks like the 6.2 would get similar mileage as the GX does now.

The diesel attracted me with the better gas mileage and diesel in my area is cheaper than premium. Premium in my area is $1.00 more in my area than regular unleaded. I do a fair amount of driving around town. Even driving 3 miles can take 15/20 minutes with our constant traffic.

I do have a boat I would like to tow, it is a Pair Custom 24. Weighs in around 6/7K pounds all together probably. Don't honestly know how often I would be towing, probably not a lot as it is kept at the marina. The furthest I would tow ever would be 4 hours away and even then...ick.

So what would yall do? Get the diesel and forgo the Supercruise or get the Duramax? Or do I just go with the Yukon diesel and get over the screen??? The GMC dealers around me are not too highly rated when it comes to service.

Buy the motor and fit everything else around it.......OR......Get the Yukon. A good chevy dealer with a good diesel mechanic "could" easily work on the DMax, but that will be far less likely than with the 6.2....

I was going to come here and ask similar questions as I am also weighing between the 2 engines. In my case I am considering moving back to a Denali Ultimate pickup truck VS the Yukon. I have a 2022 Yukon Denali with the 6.2 that just ate a rod so I was debating switching up to the 3.0l. I don't do as much highway driving as you and have a lot of short trips during the week which aren't typically great for DEF systems on modern Diesels.

With all that written, I test drove a LZ0 AT4 Sierra just to get a feel for the 3.0l and I was definitely impressed with it. It's a little doggy getting on the highway but it's also not a race car... I still can't decide which engine to choose. The 6.2 left me peeved. Although, I feel like the odds can't be so bad that I get another failed 6.2 lol.

I really like the 6.2. I drove mine today. I kept thinking this is like driving a rocket on rails. I have 2 Tahoes with 6.2’s. 23 and 24 premiers.

If you are afraid, then of course it is better to take a diesel engine. But 6.2 is the best engine))

Yeah I am so torn on what to do. Lots of driving around town for sure, stop and go traffic, sitting in traffic. Love the mileage of the diesel but worried as well driving around town. Also worried about the 6.2 haha. Cant stand the GX though!

Neither. The 6.2's are having a lot is issues currently and the baby Duramax is absolutely suffocated with emissions control nonsense that will fail , will cost a fortune to fix, and will reduce engine life among other things.

I'm a diesel guy mostly (currently own three other diesel powered vehicles), I wouldn't touch the baby Duramax.

If you're set on a Tahoe/ Yukon, then the safest bet for engine appears to be the base 5.3.

I don't think you can go wrong with either the 6.2 or the diesel, based upon your stated use cases. The diesel will provide better gas mileage, but the 6.2 will be more fun to drive, if you like to drive spiritedly (versus just using the vehicle to go from point A to point B).
