Well, I was wondering about purchasing a pint or so of straight nitromethane to up the content in the gas I have. I'm not sure if it is cost effective but I've decided that 15% just isn't good enough and that my 4 strokes really really like 20% and I'd like to try 25% or 30% but I don't want to buy a gallon of EACH just to give it a shot.

Any leads? Google didn't turn up much...just 5 gallons or more.
