I run 93 because my ECU is tuned for it. I have the ability to revert back to 87 if and when it becomes too expensive to keep buying it. The added timing with 93 makes for a quicker car, that's for sure.

If you have a performance car tuned for 93 out of the factory, use 93 unless you like to knock.
