E85????

[Ryan from Ohio]

If your car is not made for use with it then dont use it.

Pretty simple.

Go ahead and try when your on E next time.

Isnt this the fuel that will gel stuff up and clog injectors???

bio-diesel dawg.

Ryan, think of ethanol as an alcohol, it evaporates just as fuel would, and is actually printable without petroleum products added to it. It's possible The gel might be from methanol... I don't know much about methanol only that its the fuel to be careful with.

like i had said if i decide to use E85 it would be on a boosted engine not the stock one... but on the availablity i have 5 stations around me all within 10 min. but that is cause im from iowa and of course it comes from here, and another side note if there were to be a E85 fire there has to be a special fire surpressant water won't do anything to put it out you have to have a foam to fully put it out........

Fuel trim for the win! Most newer ECMs could adjust for E85. The real issue is changing to ethanol compatible fuel lines and etc....

There's no such thing as ethanol compatible fuel lines. Think about it....... you run ethanol in your car everyday. The government is actually thinking about bringing up the minimum of 10% to 15% in all fuels

Some places is already at 15%.

The fuel lines in late model cars are already made to take ethanol blended fuels.

what you're saying... actually isn't the big issue.

[Alerojester]

Spy i like how your kinda seeing it as something that's possible without discuraging someone

[kwhauck]

it is possible, there is a shop in south dakota that specializes in tuning big HP cars on e85, and they have worked with HP tuners

[Alerojester]

thank you Kyle for that piece of information as im still on the fence post about doing it with the boosted engine when it gets done

[Cliff8928]

Just don't do it expecting fuel to cost less... You're going to burn E85 significantly faster than gasoline.

There ARE specific gaskets out there for E85.. one GM V8 uses for sure I know (The that develops a lot of internal vac leaks... forget the actual engine name). The E85 ones are green, vs normal ones which are red or something.

Despite supposedly being safe even in a non flexfuel car, I'd never pump E85 into my tank. Too risky for no gain, IMO.

Normal fuel has up to 10% ethanol in it.. I've tested my gas a couple times for the hell of it around here, and I've gotten 2 maybe 3% ethanol in it. Not much.. but regardless, it's not the same as E85.

Would you rather dip your hand in a glass with a 5% mixture of acid.. or an 85% mixture of acid?

Power to ya if you're running E85 in a non compatible car, you're proving me wrong.. but I don't need anything else to worry about breaking on my vehicles.

You also sound like the type of person that would forget about the part about setting up the fuel system to handle e85 & blow your car up.

The part about it being too risky for no gain is absolutely 100% false. When someone wants to retune their vehicle on e85, here's what you tend to gain. Your emissions go down, the ethanol cleans out your fuel system (which is why you should change your fuel filter after a few hundred miles into the e85 conversion), and the bump up in octane allows you to tune in more ignition advance then stock, also as already mentioned it has a cooling effect on boosted applications & acts like crack for the car YUM!

Here's another thing that people don't realize. Running c16 will eff up your car too if you don't set it up right for your car.

here's my experience, been there seen it know it works, when done properly.

Your comment about acid is laughable. E85 is not on that level at all that it's going to eat our motors & fuel lines to pieces.

Why yes, I am a rube who knows nothing about cars.


The acid is a comparison. Obviously E85 isn't caustic. But the point is it's not good for rubber parts that weren't meant for it to be around. Keep putting E85 in a classic car and the fuel system's toast. Normal gasoline won't do that. There's obviously a different in it's corrosive properties towards rubber parts. E85 vehicles have slightly different rubber parts.. should a normal car hold up to it.. yea, but they're only engineered to see levels of 10% or lower.

And since apparently we're making generalizations about people in this thread.. YOU sound like the kind of person who makes dumbass generalizations that have nothing to do with what I posted.

I've just seen and was elbows deep in quite a few cars that have ran for more than just a season on the juice. You are making it sound like a car is going to fall apart if it runs the good stuff for more than a year. If I wanted to I could point out a helluva lot of cars that have proven that theory wrong.

Yeah, no shit about the running more timing advance and cooling on boost. I was tuning with 91 mogas and had some wicked KR that I couldn't tune out with fuel and only went away with a ridiculous amount of timing reduction. I put in E85 and retuned....holy crap, the KR went away almost completely. Was able to run more timing with no issues.

a word of caution regarding the octane levels of e85... i read a blurb somewhere not overly long ago that followed a study that took samples and check the octane level of e85 fuel from an array of gas stations across the midwest. they got readings all the way from 110+, to below 85. notice that e85 is not labeled as having a certain octane level. as a generality, yes it's high, but the longer it sits, the worse it gets. so if you are maxed out on timing and tuned for 100 for example, and you get a batch of sub 85, you're engine is going to hate you.

I believe that the "Main Spark, Low Octane" table in the PCM may compensate and pull timing out in that situation, at least in theory. However, some tuners copy the High Octane table onto the Low Octane table as part of their tuning method.

Part of this is true, however, anybody that does their research should know that when using e85 you test everytime you fill, (if tuning for max power) and add pure ethanol to bump it up. There are also winter and summer grades of e85 that can account for these differences.
