e85

oh my god i hate you.

E85 IS NOT CORROSIVE AND ANYONE THAT SAYS THIS OR TELLS YOU THIS IS A COMPLETE ****ING MORON. ALL SEALS AND FUEL LINES HAVE BEEN PREPPED FOR RUNNING ETHANOL FOR YEARS!! WHY DO YOU THINK CARS DONT JUST FALL APART FROM RUNNING THE "UP TO 10% ETHANOL" IN REGULAR GAS?! TAKE A CHEMISTRY CLASS.

do not start rumors about this. you need two things to run e85:

1) bigger injectors
2) a tune to make those bigger injectors run right

and possibly a third:

3) bigger fuel pump if you intend on trying to go for a BIG build



it really depends. im not sure that e85 would soak up the effects that an intercooler would produce.

Ok, I have a question on this..... I have been told that alcohols tend to clean metal surfaces and leave no oil residue behind, so in turn if you have a plain steel/aluminum surface it invites oxidation to occur since there is no protective barrier on the surface anymore. Gasoline on the other hand, even with a trivial (10% or less) of ethanol, still has enough petroleum distilates in it to provide a barrier on the steel/aluminum surface to prevent oxidation from occuring. This situation would be even more prevalant in the areas of the country north of the "rust belt" where the freeze thaw cycles would invite more moisture collection. So to be clear it's not the e85 that is corrosive, but how "exposed" it leaves the metal to oxidation.

So the first question is.... Whether or not alcohol based mixtures clean metal surfaces enough to promote oxidation? I honestly don't know the answer to this question 100%, I only know what I've read on the subject. Maybe someone here has some hard proof on this issue.:)

i doubt it would have any more of an issue than regular gas due to it being on the inside of the motor/lines/tank. i have never heard anyone having any problems with oxidation when running e85.
 
I haven't either, except that the "flex fuel" vehicles that are already tuned to run on e85 have stainless steel fuel lines, so there is no chance of oxidation on them.

in fact, every gas in the U.S. now has 10% ethanol in it anyways.

False. Hardly any stations here have E10. There were some back when gas was almost $4 a gallon, but since it dropped they all went back to straight gas. The two stations on base have always offered 100% gasoline.
 


Pretty much every where in Iowa has e-10. Don't know why tho..................................................................................................



OH yeah we have a **** ton of corn everywhere
 
same here in nebraska^ the super unleaded is 90 octane and E10 and the premium is 91 octane E10...but the premium is 30 cents more expensive. huge rip off imo.
