So, what would be engine recommended for someone buying a truck right now?


The 5.0 is a great engine... With too many Chinese electronics all around it. And the transmission is dog shite.

I do NOT want to have to warranty anything. I don't want to make a single non maintenance repair for 200k miles. No current truck offers that reliability.

My office mate just had her ‘23 Yukon XL roll over 100,000 and on her way home last week, all the dash lights came on and the car practically shut off. She got it to the shop and is waiting on a diagnosis. The code is a cylinder 6 misfire, which could be anywhere from a few hundred to a $10,000 repair.


My truck did the same thing at 105000 miles. It was a $50 coil pack that is plug and play. People need to get themselves a OBD2 (even a cheap one) it could possibly save you thousands. Quit bringing your vehicle to a dealership to tell you what the problem is.

Outside of the Corvette, I don't think current GM has anything that you can really say is better than its competitors.


Tahoe, Suburban, just about any Caddy and Buick says hold my beer....

If they made a 4x4 diesel version it may displace the F250 as the quintessential Louisiana douchemobile. Id buy one.

Only if you squat the rear and put 37s on it.

Sounds like it's the L87?

My 6.2L LS3 runs great.

Right.


But Im not hauling around 2+ kids, a wife, and a dog regularly.


I'll put a short list together for them, depending on their price point, needs, etc., and always look at IIHS ratings.


I guess AI can do all that now.

I totally get it.

Nothing like hitting the pedals on a machine that has true power and just letting it go.

Most reliable thing GM currently produces. Mine will be undergoing weight loss as soon as it's not Africa hot.

How many Tundra failures? From what I understand. It’s not many. Still…not what you want to hear from Toyotas. I would like to have a new Tundra, but waiting patiently.

Could have stopped at “Don’t Buy A GM”


Back in the day, yes.

You could rely on Dodge being the worst, then Chevy/ford being a good bit better, then Toyota for real quality.

Now: they are ALL shite. Every single one. And they cost more than ever.

I've yet to find an engine that didn't produce less wear metals on 0w40 as opposed to whatever was specced.

My truck specs 0w20, got that for the first 130k, got 0w40 for the last 100k miles.

Previous truck specced 5w30, got that for the first 120k, got 0w40 until 360k.

I’ve had zero problems out of my 6.6 liter L8T. It has plenty of power and none of the DOD/AFM crap. Only down side is MPG but it’s a 2500. Had it almost 3 years now and not a single engine issue.
