The only requirement for our engines is that the oil must meet GM 6094M standards. It was in my manuel

Wait who is Manuel? Was he there cutting you grass?

Mobil 1 FTW. 5W-30 here.

i switched to synthetic at 110k, no problems here at 150k...i have been using 0-30 mobil, its supposed to cover the 5-30 and 10-30 warrantys...i noticed a LOT less of the notorious gm chatter at cold starts with this oil over the standard 5-30 synthetic. I normally go 7500 miles on changes too, oil seems ok to me afterwards.

IMO--pretty ballsy to switch at that mileage. I can't tell you how many times motors have gone by the way-side just because of switching oil types. Unless you flush the motor and install a new oil pump, I would be weary on switch oil types at that mileage. But you are one of the lucky ones.

Christain has a thing for "Manuels" apparently.

But the best thing is that TRAVIS was the one who caught the spelling mistake. Yes folks--Travis.

did it on our tahoe at about same time (02 5.3) ...and every other car i've ever owned. There's not THAT much difference. Synthetic has a lot of myths involved. Besides it not sludging, and not breaking down as easy...it's the same stuff. I'd trust synthetic in high mileage motor over conventional.
