The local Valero gas station by me sells E85 for like a buck cheaper than "real" gas.
Can the Yaris run corn juice????:iono:

E85 is costs less, but cars running it get FEWER MPG than regular gas...
pretty sure you have to have a "flex fuel" vehicle to run it but as previously stated your mileage will not be the same. it all evens out in the end.
if you have a vehicle that is made for it, I think it does better but it has to be made to run the stuff.
not 100% but that is what I think

Sounds like a waste of corn/food!
I was also curious to see if the yaris fuel system could handle it without being damaged.

This is a good Q and A on E85. The main reason you "can't" use it in the Yaris is that the ECM isn't programmed to deal with the difference in target AFR required to use it. Also, it's not quite as economical as you might think, since if you added a piggyback (and larger injectors) to tune for it, you would use about 30% more E85 fuel.

If I recall right, the injectors cannot handle the e85 and also since there is
so much alcohol content in that stuff, it'll eat/rot out your fuel lines like no other.

That turns out to be a fable. Vehicles built since the early 80's use rubber and plastics that are not susceptible to alcohol. The biggest concern with E85 is its ability to absorb water and hence corrode ferrous metal parts.

Enthanal use should be shunned by all consumers! Dont encourage these a holes by buying their crap!

I've driven my Yaris in 45 states and in some states the octane rating for the standard grade unleaded is 86 instead of 87. My car has never run differently to any noticeable degree after such fill ups and I've never had any fuel related part fail. However, re 85 octane gas, the previous posters on this thread could easily be correct.

^ Hes not talking about 85 octane, but E85, i.e. a fuel blend that is 85% ethanol from corn or other biomass...
It's interesting to note that a lot of tuners seem to use E85 as a cheap alternative to race gas, since the octane rating is comparatively high... and they're not too concerned about mileage :D

so i guess no one hasn't used E85 yet huh?
any update OP?
this might help http://www.change2e85.com/servlet/Page?template=Myths
i would do the conversion... if i had money.. hehe..
http://e85prices.com/california.html at the lower right corner of the page, there's a calculator.. unless someone has done actual mpg calcs on their yaris, we can only assume, that even with a 10-15% reduction in mpg, E85 is still a good deal..

It's already blended in with your gas, and has been for a long time: http://en.wikipedia.org/wiki/Gasoline#United_States
It's very hard to come up with something that can rival the energy density of petroleum based fuels. The fact that they can get as close as 70% from fermenting corn is pretty impressive.

no it isn't. Destroying a food source to use as fuel when a much better fuel is already in use is really dumb. It is one of the factors that is driving food prices up world wide. If we wanted to use alternative fuels, diesel and people that convert them to using old vegetable oil as fuel, now that is impressive.
Adding ethanol to gas makes it both more expensive and get worse gas mileage. It is a total disaster to everyone that does not sell corn for profit.

E85 on a boosted 1nz would be
The only way to go. Yes, your target AFR is richer on E85, but you can make a lot more power per psi of boost simply because E85 has a much higher octane rating than even "premium" fuel, which allows you to gain back those timing retards you had to do on regular pump gas. Long story short, boost and E85 are a GREAT combo.

I have used it many times in South Dakota area and no problem. There is usually a gallon of regular gas when I put it in.... no sweat.....the alcohol should clean injectors a little bit.
btw 310K on my 07 Yaris hatch. NO BULL

Nope. Modern flex fuel car fuel lines are different composition than normal E10 fuel lines.

i recently saw a gas station that stated their premium had no ethanol in it...my tank was full, else i would have filled up with it and seen what the difference was.

why do you need premium?

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.

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

I've used no ethanol gas in my Tacoma.didnt notice any better mileage or it ran any better.my scangauge didn't show any differences.and I don't think a US spec yaris will run on E85.

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?

Pump gas here in the US have been adding 10% ethanol for years now. I have seen no ill effects on any of the cars I had during that time. You should be good.

Here in the UK i think some of the supermarket fuel is as high as 15% ethanol. Even the regular stuff the petrol stations sell is 5 or 10% ethanol. I think regular unleaded is better but i don't think it will do your vehicle any particular harm.
