Well, I have a Flexfuel car but I don’t see how I could receive it, HA. BTW I have never put e-85 in it yet.
My mom will take it! She has a 2011 Nissan Armada with flexfuel…But I doubt you live close enough to me…lol.
In addition to all he good advice, I would go to marine supply store and pour marine grade stabilizer in it as well as the apropriate emzyne to help neutralize some of the effects of ethanol. Do this after you siphon as much as possible out and replace with fresh low ethanol mixture.
