The pumps I use are single hose pumps and the guy/gal before me obviously due to high price of fuel is putting in the lowest octane and cheapest fuel he/she can use. Now I come along and use same hose to top my bike off with 93 and I am actually getting the cheap fuel that is in the hose all the way back to where it mixes the fuel at pump. That could be a half gallon or more of cheap low octane fuel that I am paying top dollar for. This is crazy. I think I am gonna start fueling at stations with separate fuel nozzles. AM I NUTS? Anybody have any thoughts on this?
