Can the Yaris run on E85? Anybody try it?

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

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.

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.
