Ugh, I hate when people quote others I have blocked.

It comes down to having the proper rated parts. My setup has zero factory parts. It is all aftermarket besides the actual plastic gas tank. So I'm not worried. If you are gumming up injectors with E85, you have a part that isn't compatible. So fix it.

 

It has nothing to do with what it's rated for... It has to do with what e85 itself does from sitting. I've ran e85 with non compatible parts, never did I have one failure from e85, because I never let the e85 sit. It was always fresh. People run e85 with id2000s all the time without issues, and they're technically not compatible. The problems don't start happening until it sits.

 

It has everything to do what it's rated for. GM, Ford, Toyota are not going to create something to run a fuel and "EXPECT" end users to drain there tanks if they happen to be full of e85 if the car sits for a month or more. Not nearly 20 years after the tech was available.

I should be able to buy a new Chevy 4 door sedan, fill the thing with e85 and park it for for 6 months, in any climate and it should be just fine. You can not debate this.

My point specifically here the tech that built that sedan to handle e85 most likely made it's way into the corvette's factory system. Orings, pumps, lines, with respect to these components there's nothing special. I'm sure that's why there's all kinds of valve/vents with wires to them to prevent air from getting into the tank when the car is off, thus preventing water from the air getting into the fuel.

 

How long have you been running e85?

 

It doesn't matter.

Answer my commands about that 4 door sedan? Would I have issues running e85 only in that car and letting it sit for half a year?

 

Well what happened with letting a tank of e85 sit in your 4 door sedan after 6 months? Let me guess, you dont know because you are basing your questions and statements off of theory, not facts. Show me where your 4 door sedan manufacture states it is perfectly safe and acceptable to let it sit for extended periods.

Everything Im saying is based of of personal experience, not what I read from some others guys post. Maybe you live in a dry climate so you wont have the same problems we do down in florida with humidity, the bottom line is e85 should never sit for long periods.

 

Also I was not aware OEM flex fuel injectors were SS internals.

 

LOL. You obviously have zero engineering experience. I'm obviously basing my comments on facts with regards to the 4 door sedan. It's all rather common sense.

Engineering 101, if someone can do it, they will, so design for it, like leaving e85 in the tank and being parked for long periods of time. But yeah. My point about the 4door sedan sitting is proven here: https://www.chevrolet.com/content/da...ers-manual.pdf

Go out, buy a new Tahoe,fill it with e85, park it. It's designed to to sit with e85 in the fuel system for ever.


The only "assumption" I made (and I pointed this out, as I don't know) is GM is using many, if not all, technology from that 4door sedan in corvettes for things like, plastic the tanks are made of, orings, fuel lines, etc. That makes good business sense. Part numbers that you buy may not be identical, but the teams building stuff are not sourcing different raw materials for a vette over a Tahoe.

 

Where exactly does it state its safe to sit for long periods of time? I couldnt find those FACTS anywhere? You have not shown one fact. You have no experience with e85 at all. E85 is hygroscopic, it can retain different amounts of water per ounce depending on temperature. That is a fact.

I never once said part X is going to fail at Y time. I said I wouldnt recommend letting it sit because parts can fail, and they do. Depending on your environment it can last for Y time. I will not risk it because I have SEEN with my eyes first hand what it does. You sir have not, you can only tell me what you have read.

"Go out, buy a new Tahoe,fill it with e85, park it. It's designed to to sit with e85 in the fuel system for ever."

I dont even know how to respond to this statement. Forever... You do realize regular gasoline goes bad over time right?

 

You are obviously not comprehending simple logic. Shall I find a 5th grader to help you out?

The very fact that there are no instructions on how to handle e85 fuel differently than conventional fuel proves that the enduser is to treat the fuel (and fueling process) no different with exception to what is actually outlined in that manual, namely additives for example

See auto manufactures need to make things as idiot proof as possible. You are certainly proving to be one of the bigger idiots.

 

This thread needs more *****

 

I'm an idiot for you claiming to have facts that you just admitted you don't have? So now you're an engineer and a chemist!

Just so everyone knows e85 will last forever, that is a FACT.

So the guy with no experience and no data to back up anything he says and the smart one here... Bravo

 

dude man is right and you guys should listed to the voice of experience so I'll add mine. I ran an "alchy" drag car for many years. I found that it I left it parked full of alchy for a month or more the barrel valve on the "flying toilet" gummed up to the point that car would barely run.

now these barrel valves (that control the flow on mechanical injection) have no complexity and much bigger "holes" than injectors.

while the amount of gas "lessens" this affect a bit, and helps starting

I found his advice to be true and started "pickling" the engine after running at the drags and experienced ZERO problems after that. I'd simply run a bit of regular race gas through the system and shut it down with the barrel valve adjusted to "lean it out" (takes less gas than alchy).

so I agree that the flex fuel setup is the best of both worlds as earlier posted for low hassle. As long as you are driving the car often and refilling the tank, no worries. If you are going to let it sit run the tank down or drain it and fill with pump gas.

and yes the quality of the "E85" varies quite a bit from E70-E85 which affects the tune. so again the flex fuel sensor is a hero there

and for sure "end to end" the fuel system, (injectors, pumps, lines, reg, ect....) has to be fully E85 compatible. many of the problems are from these components breaking down after many months and depositing junk in the filters and injectors and this can lead to some major issues (like a clogged injector).

just my .o2 so you can rub the bumps on my head!!

all these challenges aside, E85 and boost go together like poor man's race gas. hoping e85 becomes a bit more widely available, but ordering it drums although a hassle, is what I did for years with the alchy, but then again, make sure you will be using it often or pump gas is king, albeit at reduced boost/power.

I'm going to try a haltech with flex fuel and E85 if I can muster the funds to complete my build. that has proved challenging. EVERYTHING has to be upgraded and any "cheapo short cuts" will lead to rapid disappointment.

 

Did you know, in that manual, under Vehicle Storage sections it states nothing about fuel?

That's proof that you can put e85 in your new car and let it sit as well as my earlier comments.

How about your turn kiddo, you find me documentation from GM telling end users that e85 is bad for their new 4 door sedan

 

All valid points, considering you built a car using components not designed with e85 in mind.

but Dude_man is dead wrong on a factory car with a flexfuel badge on the back.

 

You were the one who tried using that scenario not me. I was simply telling you to prove it, which you can't.

I'd like to see how many people agree with your forever comment though.


I never said e85 was bad... I run e85. I said don't let it sit for long periods.... Which you can't seem to understand, so resort to name calling since you're on the Internet. If you're ever in mid fl we can go have a drink

 

I did prove it, you are just to dense to understand.

 

No actually you didn't. You said the engineers designed it to work with e85. Which I'm not disagreeing with... You said it will last forever, but you have nothing to back up that claim.

 

LOL, Do you see a disparity between 1 month and drain as you are suggesting and something more closer to reality, like a year? Maybe two?

Regardless of the time frame. The very fact that that manual has information about tire damage during vehicle storage and nothing about fuel should be a clue.

I've actauly spend a decent amount of time while I wait for things to compile and test run looking for decent info regarding storing vehicle loaded with e85. The results are zero thus far.

 

I said I recommend no more than 1 month... Recommend key word! Did I say it was going to ruin everything or anything? No I didn't because there are no facts for me to claim such a thing. Who is the dense one now? You're trying to twist what I said to make your look better. Notice how no one is agreeing with your claims? What does that tell you? You have no experience with it.

The last thing I need is bad fuel causing detonation or part failure in my car that I race. Something as cheap and simple as draining a tank of gas is worth it for piece of mind. And since the engineers at t1 and some in the thread agree with me, I'd say that's good enough info for someone clueless to listen to.
