I accidentally put ethanol in my 2013 Toyota Camry will this damage the engine?

No,it will not hurt it,

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.

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.

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.

My car is 2013 camry and it 91000 miles and i us3 e 10 gasoline because is only gas you can find..no problems my car run really good

@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.

I had never heard of ethanol problems, and put ethanol in a 1993 ES300 Lexus, Results fairly quick, within 24 hours. Lots of knocking and,trouble going faster than 40 mph. What is the best course of action? without a car for the weekend and need to take some action Monday

E85 is not it's not 85% ethanol read on the pump very closely it's usually around 51 to 54%you will not hurt your vehicle higher octane is average is about 107 Venice in your engine will get a good clean out I have a 2003 Camry and I run E85 in it once in awhile no check engine light no nothing runs fine

this is my 3rd tank fill of E85 gas, started getting check engine light and P0171 code. I will try to remove this gas and go back to regular fuel.

Where do you guys live? ALL fuel in the USA has AT LEAST 10% ethanol. I don't know why Toyota does not build E85 engines but Mopar and GM have been E85 compatible since 2010.

We still have ethonal free gas, at least it says so on the pump. 87 regular unleaded right next to the 10% ethonal pump. It's what I use in my 83 Jeep Scrambler. Coming from Iowa

just a few times it wont hurt, but if you keep doing it for a year, you might get some kind of damage... the check engine light will come on because the OX sensor thinks something is wrong, but just go back to reg gas and the light should go away.... it did in my case

These answers here are plain idiotic. The best remedy for this is to keep adding regular gasoline to the tank to dilute the E85 down in percentage as quickly as possible. In other words, drive 60 miles then add 2 gallons of regular gas. Keep doing it until the E85 is down to 10 percent, the norm. It will not kill or even harm the car. I've run my Camry with 50 percent E85 several times and the vehicle seems to like it, actually. I wouldn't go full-on E85 because eventually it will cause sensors to fail and other consequences. For a one tank mishap and the remedial efforts I just described -- it will be just fine.

Son has a 2018 Camry, and it stops running. by all accounts, it was the fuel pump. Have a bumper-to-bumper warranty, so took it to the dealership they said he filled it with e85 gas, and it damaged the fuel lining and spark plugs. went to the gas station, and they do not sell e85 gas, but the dealership not budgeting. Have paperwork from a gas station and documents from an atm card showing the purchase. can anyone explain this?
