Default Re: Using E-85 as an octane booster...(mixing with E-85)
Before anybody chimes in...I guess in order to get 93 octane I would need about 1 gallon of E-85 (105 octane) per 6 gallons of Premium (91 octane) to get 93 octane as an end result. Maybe a tiny more than 10% ethanol....but haven't done the math on that yet.
