Fortunately, if the price spread is large enough for it to be worth trying, I should be safe to give E85 a shot in the Jeep. Fuel rails are steel (not stainless), and AFAIK, there's no aluminum anywhere in the system, and the gaskets should all be ethanol compatible (and E10 certainly hasn't been an issue). Not sure how it would do for mpg without more compression though, as it's only 9.1:1, and the timing is already pretty cranked (needs 91 octane minimum).
