No, as long as you have an EPA certified flex fuel conversions system installed. All vehicles produced after 1995 are required by law to be ethanol resistant. Some car dealers are spreading rumors and charging $300-$3000 for cleaning out one tank of accidental E85 use. One tank full may cause misfiring and a rough ride. Your check engine light will come on. If you should accidentally or on purpose put E85 in your vehicle, drain the tank, put in regular gas and all will be well. If you use E85 without a conversion kit or non-Flex Fuel capable vehicle for an extended period, you can damage your engine or the emission components.
