    My staple boost

    Comments On Jan 29, 2015:I have not found any other octane boost out there that has all of the good attributes of the Maxima Hi-Test. First, it works as it stops the pinging. Secondly, it does not stain plastic fuel tanks (as some other brands do... watch out for anything sold in a metal can if this is a concern for you) Thirdly, it does a great job of conditioning the fuel. I've stored bikes for 12 months + with no additional stabilizers and had no issues with varnish or fuel clogs.

    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.
