OK, two hours of searching is enough so I'll ask here. I have a 2018 Limited 3.6. I was looking to buy an oil drain plug. Apparently there's an updated one. So on all the Mopar and dealership parts sites it only lists a 3.6 flex fuel engine for 2018, no non flex fuel 3.6. My gas door has a circle and slash over an E85 which indicates to me that it is not a flex fuel vehicle. So can someone explain to me why Jeep thinks I have a flex fuel when I don't and if parts listed for a flex fuel will fit a non flex fuel?
