P.S. Here is a secret tip: You can use any Oil in your Corvette that meets the GM Spec.( there are lots) for your Vehicle and your warrenty will still be good as long as you observe the proper oil change intervals and keep accurate records, if you don't use the dealer service dept.

I cannot understand why people do not think what GM puts in the Corvette from the factory is not good enough?
Use Mobil 1, (unless you are actually trying to find an oil that is cheaper).

Mobil 1 5W-30 oil with a WIX or NAPA Gold Oil Filter (same one). Have done several oil analysis, change oil at 0 % DIC Oil life left (usually around 6500 miles), and oil still has life left (it uses no oil between changes). Of course my 1998 with 109,000+ miles uses the maximum 10,000 mile oil life, later C5's switched to a maximum of 15,000 miles.
BTW, I previously used GM Premium UPF-44 Oil filters, but was concerned about them being too restrictive. When I switched to WIX / NAPA Gold, I saw 10-15 more psi cold oil pressure. Since the C5 oil pressure sensor is after the oil filter, this means increased oil flow.

Castrol Syntec 10-30 I don't see many people using it or many whining about it either.
