OIL Discussion

GM expects them to be beat on but the main thing is Corvette buyers expect for GM to expect them to use the stuff.

It's not just the Vette, anything with GXP or SS on it too - the idea is since there "high performance" they will be used as such, hence the better oil. But yeah Mobil 1 has made deals with a lot of companies. I've ran it, didn't notice enough difference to even care

the oil caps on the SSS says mobile uno on it!

Mobil 1 5w-30 since mine was new. No probs. That's what I recommend to all my customers with the new GM engines at my store.

man, yours isn't old enough to have problems yet. :lol: Mine is pretty old and getting close to 80 something on the clock. Still runs 60-80psi oil pressure. Also pretty clean after 3000 miles. I don't see any reason to not use it.

you can run full synthetic. its just not recommended to switch back and forth from standard to synthetic. thats what ive been told. got my truck with close to the same miles. she has 160k on the clock now with zero problems. gary

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

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. :thumb:

Christain has a thing for "Manuels" apparently. :laugh:

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

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.
