Marc tells me our engines are not octane restricted. 91 is fine.

I remember hearing that all cars sold in US must be able to operate with no damage with 87. However, most hi-performance cars and German cars will lose hp when using less than specified min. Octane.

Put simply: with active sensors and control, our motors will run at peak performance when high octane is available, but the computer will back off (timing primarily) if knock is detected as result of lower octane fuel. (1) "Corvette Fuel Injection & Electronic Engine Management" by Charles Probst.
