not enough to compensate for the extra cost. i always run 93 in mine it runs better then using lower grade fuel here. will be going to e85 when i do my build in less then a monthYeah I was just wondering if I used premium if I'd make more horse power.

you won't make more power just from running a higher grade fuel. you need to be tuned to take full advantage of the extra octane the fuel will provide.
