I accidentally put E-85 fuel in my Toyota Corolla Vehicle. I only pump 5 dollars E-85 fuel in my Vehicle. Did I damage my car already and what should I do?

Should be no damage. Top off the tank with your regular grade of gasoline to raise the ratio.

Here in California they put 10% E-85 in the gas to "make it burn cleaner" that's the most you can put in a car that hasn't been converted. You should be ok if you top off with normal gasoline. The problem is fuel hoses and seals get eaten up if not made with a special kind of rubber. If you're still worried, dump a can of Sea Foam fuel cleaner in it and top off with 91 octane. After that tank, you can just put regular fuel in it.

Fill the rest of the tank with premium, and check which brands are ethanol free in the premium grade. Here in Ontario, all 91 and 93 octane fuels are ethanol free. That will dilute the E-85 that is in the tank, bring the ethanol content down to a percentage your car can burn properly.


hell NO! it will not hurt it even if you fill the tank full! There have been many studies that prove my statement right! May effect the longevity of hoses!
