Hoping to make it to dyracuse mx park saturday... the gas station by my work have 110 octane leaded race fuel at the pump.. for 6.49 a gallon.. would it be worth it to mix in a gallon? I mix 4 gallons at a time.. only have 91 at the pumps here.. so i figure of i mix 3 gallons of 91 with a gallon on 110.. it should help keel my motor cooler.. since leaded fuels lubricate also ...... input???
