2008 hyundai accent and e85?

Question

i accidentally put e85 fuel on my 2008 hyundai accent. at first there are no apparent problems until the tank is almost 3/4 empty. the check engine light turns on. i asked my friend what to do. he said to fill it up with regular gas because 1 full tank of e85 wont do any harm to my car. so i did what he said and tried to drive my car around hoping the check engine light will go off... but unfortunately it didnt. my other friend did the same thing and she paid 500 dollars in the dealership just to drain and flush the tank? i think its a rip-off so what should i do???

Answer 1

E85 Ethanol isn't too bad.  Most cars(yours included) have natural rubber fuel lines and the ethanol will damage them. Synthetic rubber fuel lines can handle it.  E85 is only 85 % ethanol so if you didn't put too much in, you should just keep putting regular in and it might clear up.  Although I suggest that you siphon your tank with a hose and a hand pump(or your mouth).  Then go to an auto shop an clear the check engine light.  If it comes back on then you probably have a problem and need to replace your fuel lines($expensive$) Hope this helps.

Answer 2

Keep refilling the tank with regular gas. It should go off, eventually.  One tank shouldn't ruin it...it just needs to get out of the fuel system.

Give it 5 or 6 tanks and if it doesn't go off, take it to the mechanic.
