Methanol if I'm correct should be the same price as regular unleaded gasoline. I think I bought mine at 2.88 a gal. But Fab's pretty smart he recovers the most of the methanol which is the most expensive ingredent. But it should be .80-.90 a gal if you buy the supplies right. I bought 5 gals and they charged my 7.00 when I bought 55 gals it was 2.88. Just like anything, buy in bulk you'll save.
