This I copied off the internet. So that said, if oil is good enough for a Vette, and the same weight is recommended for your ride, why not use what the vette guys use?

You have made a big investment in your Corvette, and the beating heart of your car is the engine. You want to take care of it in the best possible way, but there are a tremendous variety of engine oils out there - which should you use?
Here are the basic engine oil rules:
Any Corvette built since 1989 needs the specific oil recommended by Chevrolet for your engine. Generally this is 5W-30 synthetic oil, and GM specifically warns against using any other formulation, such as 10W-40 or 20W-50. For the last several years, GM has specified Mobil 1 5W-30 synthetic oil, and filled every Corvette with that oil at the factory.
The owner's manual for the 2010 Corvette notes that all oil used in the Corvette must meet GM4718M standard, and be labeled as meeting the standard. See your owner's manual for your recommended type and grade of oil.
Any Corvette built before 1989 can use modern synthetic oils of the same weight as recommended for the car originally, but those engines are designed to be lubricated with oils containing Zinc Dialkyl DithioPhosphate (ZDDP).
