Who has run E85 long enough to tell if there are any long-term issues with fuel lines/pump/injectors? We've all heard the horror stories about ethanol eating up these things but I would like to know how much is truth and how much is fiction. If the material compatibility is really such an issue, what are the alternatives? Do flexfuel vehicles truly have an entirely different fuel system? Can some of these components be used in our cars? I've been running E for about 3 months now without any issues and plan to go back to E91 for the winters.

 

adrian, have fun going back to 91 haha when i swapped back my car ran like **** for a good tank or so then it started to run normal, but right when i started it up it would pop soooooooo loud haha like a gun shot out the exhaust

 

Oh, I've been back and forth a few times whenever the car needed to go into the dealership for another warranty part replacement haha
And you're right from E91 to E85 is no problem but back to gas the car is definitely NOT happy with ethanol in the lines!! I usually let it idle for a few minutes at the gas station and then it runs really rough the first few miles. And yes, I've also had it pop and backfire like crazy! The worst part of going back to GMS1 though is losing all that power, just feels like a dog!

 

haha ya it sucks! do you have your own copy of HPT?

 

No but I haz a second ECM =p

 

oh haha lucky you!!

i need to run E85 when i come back home, i cant run it now because i run out of fuel here at sea level lol

 

Gotcha. I run about 15% lower mpgs here but then it's 15% cheaper than premium so there you go

 

nice lol well im gonna sub this thread cause ide also like to know

 

Eh...roughly 4 months and 5-6k miles here and no issues...I wouldn't imagine seeing any issues...especially for those of us on the E47 Blend

 

I still am not convinced E85 or E47 is good. Sure power performance, but I've been hearing so many bad things.

 

I have run full e85 through about 8-9 tanks with NO issues to report other than a shitty cold start idle which I have fixed.

THe power difference is HUGE though. TO each there own, it does run like poo for a bit after a switch back but that is to be expected.

 

i havnt heard any bad things what did u hear?

 

ya when i swithced back mine ran like **** lol kinda scared me to be honest, ill prob go the E route when i go back to colorado were i have people who can tune it on speed dial lol

 

^^^This.
This is why I don't think I could ever go back to E91 permanently. The power differential is simply astonishing. I'm still looking for people who have run ethanol for a longer period of time. I would imagine that IF there are material compatibility issues within the fuel system, that they wouldn't exhibit themselves until after some time, I'm thinking a year or 30,000 miles. I'm not sure if there are any cars that have been on E that long yet but I figured if they do exist, this would be the place to find them...

 

There are ways to make it cold start as well. I had issues here or there but after a couple cranks it did start right up. It gets pretty cold in the PA mountains here also..

Ive been running it for 8-9 months now, car has sat a few times for a week or 2 and had no issues. Ive toyed with going back to pump gas but then I do a WOT pull and that thought is gone lol.

 

Two of us (that I know of) have had inj head seals start to leak but they were completely gone when we pulled the injectors. I'm not saying the E ate them away, just that if they were completely missing upon install, the E may have cleaned the carbon out of the mechanical fit & seal.

 

Ive been running e47 for about 10k miles now with no issues what so ever. I have tyuio replace my injector seals but that's because when I did my motor build and pulled the injectors your suppose to replace the seals I didn't know that at the time

 

100% e-85 for a little over 6,000 miles
everything seems fine

 

I've ran E85 on my car for over a year. No issues. But then again I'm running dual in-tank walbros Aeroquip 8AN feed and return lines, Aeromotive FPR, InlinePRO fuel rail, ID2000cc injectors, and an AEM EMS standalone. It cold starts in 0 degree weather in 3 cranks. If your cold start is taking too long, you need to add more cranking fuel. A good tuner should be able to figure it out.

 

In for some more info im thinking about switching over to e85

 

D1sclaimer I wanna punch you in the face so hard for how bad I just got rick rolled! I couldnt even leave the page hahaha

 

my buddy's ss/sc has been on full e85 for about a year no issues.



from wikipedia--Rumors about being corrosive

There have been many rumors going around that E85, which is biodegradable in water, can corrode a vehicle's fuel system, including the fuel tank. Although E85 is corrosive, it is not much more corrosive than regular gasoline. The chemical properties of E85 are not what causes the corrosion; it is the water in E85 that may cause rust and block up the fuel system. In fact, gasoline also contains water, which is why vehicles' fuel systems are built to resist and prevent corrosion.

Vehicles today (mid-1980s and later) are built to withstand and resist corrosion, which means E85 is very unlikely to harm or corrode a vehicle's fuel system in any way.
