E85 will always be alot cheaper, i know around here right now 93 is going for about $3.10 a gallon and e85 is only $1.50 so that is quite a huge drop even if it doesnt last quite as long still should be a saving as long as your not out foot to the floor all day everyday :cheers:[MENTION=13776]xmustangx[/MENTION] According to Livernois e85 can add more power but you will typically see a noticeable loss in fuel mileage since it requires nearly 30% more volume to meet the same need as gasoline. The mpg could be a wash because of the price difference between e85 vs 91 and 93 octane. In my area e85 is always cheaper. I'm currently using the flex fuel tune.
Always nice to get more power while spending the same or less though, just a bonus! :cheers:LOL E85 is not for mileage its for horsepower........
No comprendeas long as your not out foot to the floor all day everyday :cheers:
Glad your enjoying it can't wait to join you myself! :cheers:E85 is a lot cheaper in my area too. I haven't checked the mileage on either car since new, just trying to help the op with an answer. Loving the new tune update!
