Usually a small company buys their materials from the big companies they are trying to compete with. Some good methanol and nitro, Klotz bottled oil and you've got a decent fuel. Nothing wrong with it, I ran it for a year instead of my customary Byron's and it ran and protected my engines every bit as well. A small company doesn't have the resources to do the R&D or purchasing volume necessary to improve on that.
$45-50 a gallon for Byron's in Wi.? I haven't bought a gallon in a while but it was less than $30 (Race 3000) down south in Madison. WOW.
