I nearly put E85 into my Cherokee, as I'd not heard of it, did not know it was any different from the enthanol-enhanced fuel sold in Iowa (through which I passed on the way up) and didn't know it wasn't for my truck.
Thank God for the farmer at the pump next to mine...
Your vehicle would have ran just fine. The difference is higher quality tank, fuel lines, filters etc. due to the corrosive alcohol. One tank would have meant nothing.
