I typically prefer to use major brands of gas, i.e., Mobil, Shell or BP, but we have an FS (Farm Service) gas station in town that offers 87/89/92 octane. The 87 octane is 100% pure gas with no ethanol blended in, and the their other two grands have the ethanol.
My question is, would I get better gas mileage by using the FS 87 with no ethanol in it? And would it burn cleaner/better?
It's strange, but when I fill up at BP or Shell here in central Illinois and drive to my brothers in Fort Wayne Indian I get awful gas mileage, but when I fill up there for the trip home (Indiana doesn't have to blend ethanol in their gas) I get excellent mileage, and use noticeably less fuel simply by looking at the gauge. But I can't be sure if it's the ZERO ethanol or simply driving conditions and temps.
