Best octane boost so far.

Comments On Sep 12, 2013:I've tried many different octane boosters and Maxima Hi-test reduces/eliminates detonation (pinging)without nasty side effects. (some other octane boosters will discolor your plastic fuel tanks). It also makes a good fuel stabilizer. I notice no loss in fuel performance when storing for a few months here and there, and have had not had issues with fuel deposits in my carburators. I see a couple other reviews that knock it for not adding power, I would like to point out that increasing the octane of your fuel does NOT increase power... that's not the point. The point is to reduce engine damage in high-compression engine applications, and Maxima Hi-test is the next best thing to running race fuel.

No noticeable difference

Comments On Aug 12, 2011:Used 8oz with 5 gal of 91 octane and there was no noticeable difference with power on a Harley 1340cc EVO. May still be useful as a fuel stabilizer?
