Beg to differ if it is not a flex fuel engine damage can and likely will occur. Next time pay attention to what u are doing.

That all depends on if it was E10 or E85. I don't see any E85 Camrys in 2013, so if you put in more than E10 then damage will happen. I would recommend draining out the fuel and refilling it with regular fuel, then add a bottle of StaBil marine fuel additive, it is blue in color, and that should take care of any E85 that didn't get pulled out of the tank.

I beg to differ,i run e10 in my 2012 camry,and have no problem doing it,i do agree if it is more than e10,then yes,it will hurt it.

If you live in the states then all of the regular pump gas is E10, it's not suppose to hurt things but it does, rubber lines, fuel pumps, carbs. One of the worst things the government has done to our cars sence the early 70's

I agree with you tinnisshoe,i try to run regular with out ethanol,but it is my dahugters, car and she think,s just because it is cheaper,she buy,s it,that,s how i know it will run it,but that said,i do have to clean fuel filter in it,along with adding additive,s to keep it clean,from the syrup.

Good luck finding fuel without ethanol. Purely talking about e85 this is flex fuel. EPA mandates fuel ad ethanol to everyday gasoline for emissions. Not sure how everyone got confused.

I'm not sure how people here answer this question saying that Ethanol fuel will hurt the vehicle, while they don't list any technical reasons. What kind of damage will it cause, and in which part of the car? First things first; ALL gas sold in US is already blended with at least 10% Ethanol. So if fuel already contains at least 10% of Ethanol in all cars AT ALL TIMES, then materials in all fuel and other systems, including entire engine assembly, that come in contact with fuel or exhaust products are designed to not be affected by it. Hence, filling a non Flex Fuel Vehicle with a fuel that the vehicle is designed to burn, albeit at 10% concentration, once, it will cause lasting damage... how? What incentive is it for car companies to produce cars that must use at least 10% of Ethanol without making necessary changes to materials and software to avoid any problems caused by Ethanol? Higher warranty claims due to issues caused by Ethanol content in the fuel? Think about it... In regards to cleanliness of Gas vs Ethanol; Ethanol is an alcohol, and burns much cleaner than gas. I'm not asking you to believe me, decide for your self: Take two small ceramic plates, white if possible, and pour a teaspoon of gas in one, and the same amount of Ethanol in other. Carefully set each one on fire and let the fuels burn out. Do it outdoors. Ethanol will burn cleanly with a blue flame without creating any soot, and will leave little or no residue on the plate. Gas will burn with yellow flame and will create swirls of black soot, and will leave dark residue on the plate. The same thing happens inside the engine, where ethanol will actually slowly burn off residues and deposits left by the gasoline. The only actual "Damage" that can occur is in the vehicle owner's wallet, and slowly over time, is a result of the fact that Ethanol will cause about 20% lower MPG, as its energy content is lower than Gas, which also can be addressed by reprogramming the engine's computer, the ECM/ECU.

E10 or E15 is fine, but E85 may need to be drained or siphoned out. The engine computer can not adjust for the E85 if it is NOT a flex fuel vehicle.

To Bob: You are correct in that none-FFVs computers cannot adjust enough for E85, but again, that's not the same as causing damage to the engine, and its certaintly not a cause to pay $400-$600 to the dealer to drain the fuel system; they will NOT tell you this, and will only be happy to take your money to do unnessesary work. Engine control modules (aka engine computer, ECM, ECU) rely on data from sensors to calculate engine control parameters, such as ignition timing, duration and timing of fuel injector "on" states, and in later cars, which no longer have throttle cables, the degree of the opening of the throttle. HOWEVER, no sensor determines the octane number, or the chemical composition of the fuel. The closest any modern car comes to that is the oxygen content in the exhaust gas, which is provided by oxygen sensor(s). So, if any vehicle is run on E85, which will require higher oxygen content to burn, the most that will happen is that oxygen sensor will sense less oxygen in the exhaust than specified by the "normal" operating ranges hard-coded in computer, which will result in computer compensating by extending the "on" pulse of the fuel injectors, which will result in richer fuel mixture. However, since in the none FFV "normal" operating ranges hard-coded in computer are for gas, and not for ethanol, the oxygen content in exhaust gas will still be lower (because of the ethanol's different chemical properties). The most that will result is the computer logging "out of normal range sensor data" and turning on the check engine light. However, the next time the vehicle is filled with "normal" gas, that is fuel with ethanol content less than 15%, engine operating parameters will return to normal, and after programmed number of engine start events (in most cars its 3-6 starts) the computer will turn the check engine light off, and that is ALL that will ever take place as a result of filling a tank with E85.

@Jack2756 what would happen if you used E85 in a non flex fuel car over a period of time besides the check engine light coming on?

2013 Camry takes 10% ethanol per manual, no problem.s You need a 2014 or higher to put 15% ethanol in. End of story.
