GAS

Regular (87 Octane) or E85 can be used.

E85 is an option for you, the recommended fuel is unleaded regular 87 octane, if you decide to run E85 your mileage will drop considerably but it will not harm your battery engine most manufacturers recommend you burn 1 tank of regular unleaded 87 octane for every 3 tanks of E85. Your mileage will take a nose dive with E85. I hope this helps. Take care.

My computer decided the word battery should go there please ignore it, thanks

oh ok thanks

Just put my first tank of gas in add I just bought it used at 84k miles, put e85 and it won't start.

JGK. If you put E85 in a non flex fuel vehicle you will need to drain the tank and blow out your fuel lines.

Thanks for your answer F_O_R I appreciate it. It's started and run perfectly until now and even tho it has the giant yellow E85 on the gas access door I believe the gas will need to be drained... :(

Thank you F_O_R I did the mistake in a just purchased 2016 75 anniversary edition Grand Cherokee. I filled 17 Gal. of Flex Fuel, it runs, but I will definitely follow your advice drain the tank and blow out the fuel lines and fill it up again with E87. My bad mistake.
