Also, I should add you won't see detonation on the plugs of an E85 car. I did have a friend that bought it in a 55gal drum like an idiot and by halfway through the drum he was injecting mostly water into his car (03 Cobra, big snail, big boost) and it was trying to hydrolock on every compression stroke and it would walk the crank and crap out a thrust bearing costing a motor, he ended up eating up 4 or 5 motors before we found that is what it was.
