The 2nd gen insight will run on moose piss, but loves 93 octane. You notice a boost in performance and mpg, but the mpg boost is not cost effective. For performance and throttle response, I think it is worth the extra.

Its a mixed bag, too much ignition adds nox to the exhaust. You can use more fuel to help reduce ping, but there goes your mpg.
