The best gas for a 2001 Corvette depends on the engine it has. A 2001 Corvette could have either a 5.7L LS1 or a 6.0L LS6 engine. Both require premium unleaded gasoline (91 octane or higher).
Using anything lower than the recommended premium unleaded fuel can lead to engine pinging (detonation), reduced performance, and potential engine damage in the long run. The owner's manual will explicitly state this requirement.
