Originally Posted by Navi Im my region, the Chevrolet Suburban is used very extensively. Ive known 3 guys who have had to replace engines past 100k miles and all of them used the 0W20 oil specified by Chevrolet. Oil is fairly inexpensive but to replace that engine the budget answer is $5000 and...

I've not had a problem with the exception of a Q-Lube in the late 90's. It would purposely underfill by half a quart and tell customers after the service was done the auto was consuming half a quart of oil between changes. In the nearly quarter of century since then no issues and Q-LUBE was...

Well if there is a problem oil isn't fixing it.

Originally Posted by rob1715 ST oil has a higher than normal NOACK so for a GDI engine, I'd stick with lower NOACK PP or PUP which I use in my 2019 Sorento GDI. For non - GDI engines, ST is just fine and will do the job oil is intended to do. NOACK? ST synthetic is a DEXOS certified lube it's...

The UOA looks good. As for sludge yeah you will need to physically look for it.

Funny you asked. I looked at LG Red today and decided to pass. I change the ATF fairly often and I decided against it. As for the few posts on her saying Valvoline Maxlife ATF runs hotter than DEXRON VI. I'm not seeing it.

Looks good and boring.

Looks good given age and mileage. Keep doing what you have done. Neither the motor oil or engine owe you anything.
