I have a 2016 Accord. I put a tank full of E85 fuel in it before I saw the warnings about dangers to non-flex fuel vehicles. Just how much/what kind of damage will this tank of gas do to my car?
you can tow it to a shop who can drain it if it is a real problem. I’m sure others can give more details.
Some pumps are labeled as E85. E85 is a fuel that has a much higher blend of ethanol. Some cars, labelled as flex-fuel vehicles or FFV can switch between E85 and normal pump gas without any issues, but if you accidentally fill your non-FFV car with E85, you may notice some issues.
For starters, you’d at least get a check engine light, but you can top off the rest of your tank with regular gas and ride it out. “One time misfueling should not cause any long-term damage,” said Robert White, vice-president of industry relations at the renewable fuels association. “Even that light will cycle off once the fuel mixture issue has been resolved.” He also pointed out that “accidentally fueling with extra ethanol is not like a diesel misfueling that automatically shuts down the vehicle, requires service and expensive maintenance. Consumers are usually able to navigate the issue with little issue, and the number of calls we get has dropped tremendously over the years.”
