Ok soo.. I gave up on the idea of running any additives or mixes of fuels in my zilla cause it dosent seem to be worth the hassles of rejetting, detonation and possible engine damage in my 500.  However, i have been using the lucas ethanol treatment/ stabilizer in all my 4 pokes for about 2 1/2 years now. All these quads, lawnmowers, etc. run great and the carbs look sqeeky clean when i open them up.  Never rejetted or anything.
Should i be worried about the 93 pump/ lucas mix in my 4 strokes?  The highest performing of all these engines is my stock compression yfz450. Hardly a rocketship.
