Like he said, to see what the difference was... I tried that too some time back, did maybe 3 tanks on pure 95RON, checking on fuel economy, spark advance, and butt dyno, and ended up with approximately 0% improvement over the regular E10 91RON :shrug:

Thought I would pour in some 411 to this ember of a thread.

I recently pumped ~8 gallons of E85 into my 07 sedan by accident (to an existing 2 gallons of regular unleaded). I freaked out thinking it would damage the engine, but the Clerk working that night reassured me that it would not do any damage. He said that as long as you don't do it often and dilute it with regular gasoline that the car should be fine.

I am now aware that E85 can cause corrosion to fuel lines and the engine. However, I plan to continue pumping a 1:1 mix of E85/unleaded--when ever possible.

Don't put e85 in your car. DONT DO IT! YOU WILL KILL YOUR MOTOR!

Running on e85 requires about 30% more fuel since its stoich ratio is lower than that of gasoline and its energy density is about 70% of gasoline. E85 runs nominally at about 8:1 air fuel ratio whereas your engine is calibrated for gasoline which runs between 13-12:1.


Running with E85 in the car will cause your engine to run lean, Alcohol requires and will eventually cause it to fail. Unless you happen to have the only Yaris in the country with a flex fuel badge on the back DO NOT RUN E85.

There is nothing wrong with E85 when the motor has been calibrated to use it, but when it has not like all cars that are not flex fuel capable it will cause damage and or failure.

Yes. xnamerxx. I am aware of what might go wrong. It's my way of sticking it to the petrol companies. Once I can get my hands on an all electric vehicle :cough:Tesla:cough:, I'll be happy...I can dream..

I would love to run a tank of no ethanol just to see.........................

*Not really comparable but my lawn mower/snow blower guy recommends Marine Stabil fuel, the blue one, for mowers and blowers. Removes, neutralizes the ethanol.

If you want to run E85 after you upgrade fuel pump, fuel lines and injectors and fuel filter and it get it tuned. Is that true that you can go back and forth between E85 and 93 Octane as long as you finish using all the fuel before switch back and forth.

That is correct. You would have to run an aftermarket standalone to tune it though, as it would be a bear to keep the stock ECM from trying to trim the extra fuel from a piggyback.

As long as you are fully aware this will completely void every warranty you might have on your car, go for it. Toyota specifically states not to run any ethanol at all in their vehicles. It is in the owners manual.

For those still interested in this older thread, if there is a location that sells non-ethanol fuel, give it a try sometime. After doing your calculations, you can decide if using the non-ethanol fuel would be beneficial.

Around my location, which is near the coast, the "marine" fuel (E-0 or pure gas) I use in my Yaris gives me about 3 MPG more on average per tank.

Marine and aircraft fuel will bring a ticket and fine if caught.
Road tax is not collected on those at least in Michigan, so it's risky.

yes it can run on E85 without any problem..with all that rust etc bull shit people are saying, cut it out man..

in asia a lot of Yaris or Yaris sedan convert to E85 with the E85 conversion kit..

please look at my E85 All Motor Build..I am still working on my car but I will be converting to E85 next week..
-1jz injectors (280cc...current 1nz 200cc / need about 30% larger injectors..its not a must thing but im going to chip tuning)
- E85 conversion kit which comes right over the 1jz injectors
- Advance time & ignition ECU for E85 (dyno/tune)

@nortonfb: I was unaware that non-ethanol fuel was such an issue in Michigan. Here in Georgia, gas stations proudly announce with banners that their station has "non-ethanol" fuel. I believe the non-ethanol fuel is taxed here, though.

The "marine" fuel here is used by auto enthusiasts, boaters, and lawn care services for the most part.

@ rabbito: I am actually interested in your E-85 conversion. I hope to hear more about it after your conversion next week.

The issue isn't the type of gas but the road tax. After all the state must be paid.

Hey! Reviving an old thread.

My country (Costa Rica) will start mixing 10% ethanol 90% unleaded. I read my owner's manual (2007 yaris sedan base US model) and it says that Toyota recommends the use of maximum 10%, which is good.

Will this cause any damage to the engine?
