Which Synthetic Oil?
I am going to do the first oil change on my Corvette since I purchased it. The vette has around 150K and uses synthetic. I do not know which brand the previous owner used. What are your recomendations based on my mileage and your experiences?

Pick up a bottle/jug of Synthetic motor oil. (not synthetic blend)
1. look on the back label for meets/exceeds GM4718M
2. look at the Brand
3. look at the viscosity
4. look at the price
IF it says meets/exceeds GM4718M, AND the Viscosity is either 5W30 or 10W30 ( if the air temp will not go below 32 before your next oil change)AND the brand is one you TRUST AND the price is what you are willing to pay, buy it.
Mobil 1
Amsoil
Royal Purple
Pennzoil Platinum
Quaker State
are Brands that meets or exceed the GM4718M spec.
My preference is Mobil1 5W30

Whatever oil you use I would go with a 10W-40 with the mileage on your car. My personal preference is Red Line Oil (www.myoilshop.com) or any other quality synthetic will be fine.

I agree that with the high mileage engines i would use 10w30. I think that if you switched to 10w30 that you would burn a half a quart anymore.
