Ok so there’s a couple of “flexfuel” stations on my way to work (I want to to run E85 when it gets warmer out without the FFK, maybe permanently). The one Sheetz that has it says “51-83% ethanol”. This is fine, I’ve done my research and know each station/fill up will vary with the ethanol %. I’ve seen that the OFT E85 tune can be as low E50, which I’ll be cautious of.
I’m confused though because the Sheetz I went to with the flexfuel says the flexfuel has 51-83% ethanol, but the button to fill it up is 94 octane I believe... is it not the same thing, and should I not use this?
I’m sorry guys I really tried to search this
