I'm following the maintenance schedule from GM. If following their recommendations harms the engine then why would they make that maintenance schedule? Doesn't make sense.
I traded my 6.2L Silverado for a new 3.0L diesel one and boy do I love that diesel engine! Super smooth, relatively quick and fuel efficient. Don't miss the gasser at all!
I just sold my 2024 Silverado with 6.2L b/c of the recall. Bought a Silverado with the 3.0L diesel. So far love the diesel, it's surprising peppy and there's no comparison in MPG however one thing I'll miss is the glorious sound of that 6.2L in Sport mode where the exhaust sounds like a cat...
I haven't read through this entire thread but can anyone confirm one simple question - does passing a pico scope test and getting 0-W40 oil absolutely prevent an engine failure in the future? We can now be confident it'll never happen? Or are we still rolling the dice when driving these cars...
Oh hey look, a new lawsuit.

Turns out running thicker oil ruins fuel mileage. So even if our engines are fixed the mileage gonna go to crap.
Some here saying the diesel is junk and some saying the gas engines are junk. I don't know - just go with the engine that makes the most sense to you. Here's a write up on the reliability of the 6.2L gas.

FWIW I have a new 2023 Tahoe...
OK I guess. There's nothing on the windows sticker and nothing on the display on the dashboard that indicates any kind of cylinder deactivation. Strange...
So I'm reading about all these lifter issues with AFM on 6.2L but I just got my 2023 Tahoe with 6.2L and it doesn't go in V4 mode - all 8 cylinders are working all the time so I don't think mine came with AFM. It does have auto stop but no V4.
Am I missing anything?
