I ride a 2003 WR450F, and the manual says to use 95 octane fuel or higher. Since premium pump fuel is only 92 octane I have been getting 100 from the airport. The bike runs great and clean, but am I wasting my money? I don't mind spending the extra dollar a gallon for rocket fuel if it is worthy, but I won't if there is no benefit. What does everyone else burn?
