My general, sweeping point was that higher octane in a 128 won't result in much of a difference while a 135 will benefit from a higher octane.

you're right, the only different I feel from 91 to 94 is that my car starts up easiler and smoother and ofcoz the psychological factor.

Shell V-power is great...but if you can come accross Gulf 93 Octane it is the best.
