i got the best results buy going from 87 to 93 octane. some people say im full of bs and i will agree it won't work on all cars but my got got a fairly good increas 270 miles per tank on 87
to 300 on 93. i tried som 104+ aviation fuel with no real gain i got 305 on that tank not really worth the extra cash or the hassle of goin to the airport to fillup. btw i did a little math it is cheaper to run 93 when regular hits $2.00 per gallon. like i said i know it won't work on a lot of cars but it did mine.
