I go to my local parts supplier and order 110 Octane Racing gas (not cheap!) and I apportion it into a tank (18 gallon on my rig) and I add 1 gallon per tank fill. It works for me and when it is all figured up it amounts to what I used to pay for 104 octane gas at a station in Sacramento. But it sure run better.
