Once upon a time I had a 1990 mustang 5.0 H.O. and would periodically put 110 race fuel in it I even tried leaded 110 ohv fuel and the thing ran it my guess is without a tune there is only so much the factory system can advance or retard the timing so probably won't do much but it will run it. 😉
Boom
Ethanol actually produces more then 25% more emissions then running straight gas!! I wonder what 110 race fuel would do in my truck? Lol 😆
