So a lady at work filled up her car with E85, For a 2016 non flex fuel jeep of some sort. Our old school mechanic and I talk a lot. His first question was are the gas pump nozzles different size? I said I would not think so since flex fuel vehicles can use either.
Question 2, is it going to damage the car? He called another mechanic he knows and the guy said no problem. I mentioned my CNG and regular gas work truck suggests not using cng 2 tanks in a row, intersperse with regular gas. Of course we talked about the old leaded gas to protect the valves etc. My first thought, every 1/4 tank down put regular gas in, and that was what he had recommended, but then It is maybe $30 worth of gas, drain it and be done with it.
Now she does not want to take it to the dealer, in case it voids a warranty, and it may cost a couple hundred for a shop to drain and dispose of the gas.
I said take it to the bad neighborhood leave the gas cap open, it will probably get siphoned out in no time, but we agreed the tires and wheels may be missing along with the gas.
Knowledge and insight appreciated.
