I need to be educated. Is there more than one kind of Methanol? In looking for it around town for use in a water/meth system, the only place I can find that sells it is a transmission shop that happens to run it in their drag car. He buys it by the 55 gallon drum and is willing to sell me as much as I need by the gallon. Just want to make sure this is the right stuff. I assume meth is meth and all the same unless it is premixed with something else like ethanol or nitro, correct? Should be the right stuff?
