Sometimes this place rocks, that is some of the best info thanks Fellas. My Brother was telling me to use 91 Shell cuz it's the only premium up here that doesn't have ethanol - which makes sense in the F5 Roadster (750 Holley) and the 04 Sportster ( last of the carb EVO's) but I guess I can happily run Sunoco 93 (10% ethanol) in the Mustang and the FB.

This should be stickied or an FAQ
