hehe my name is Sean too and im looking to do the same thing

i think the M1 is best because it doesnt have all those additives that VP added in like the M3 does, and its best to find some place near you to buy it from so you dont have to pay shipping on it, i can get a 5 gallon drum of M1 at a place near me for $23-24, if your gunna make a bunch of fuel, you need a 5 gallon drum
