I read the manual; it says the car can run on 100% Gas, 90% Gas/10% Ethanol and even 5% methanol. Methanol isn't commonly sold here, so what do you think of adding some bottles of this HEET (Yellow Bottle) to each tank?
HEET (Yellow Bottle) is 99% Methanol. As I understand it, Methanol burns cleaner than gasoline. My tank is 18 gallons, so 5% is 0.9 gallons. Nine bottles = 108 ounces = 0.84375 Gallons. However, the HEET website doesn't recommend to use more than two bottles per 20 gallon tank of fuel. I can't imagine it takes into consideration my engine is actually designed for 5% methanol though, so now the question is: What else is there in this additive? Or, should I look for another source to get Methanol to put 0.9 gallons in per tank if it's cheaper? One Gallon = About $15.90 if I buy them individually, costs less in larger quantities.
I don't expect to be using 0.9 gallons in to start out, maybe half that. I don't want to knock out unburnt particles too fast and clog something.
