hey
im thinking about running e85 in my evo
not sure where to ask this
but i want to get it in kinda like a bulk thing
my dad has a 500 gallon tank that i would use to store the e85 in
the question im wondering is if i get so much of it
will it go bad? will it last a while? is there anything i would need to put in it to preserve it longer
that kinda stuff
any info would be appreciated
thanks

 

E85 is much more prone to absorbing water moisture than regular gasoline. Thats one of the reasons shipping and containing it is such a hassle. A 500gal tank is going to go bad in the amount of time you'll have it.

So far I've had a barrel of E85 stored for 6 weeks that I just filled up on. It is fine. It actually is running better than the E85 I bought at another gas station the other day.

Regarding the hygroscopic nature of fuel. Yes I'm sure it is an issue but I've had no problems storing brake fluid and fuel for log periods of time. I've used brake fluid that was on my shelf for 2 years and haven't had problems with it. I bought a barrel of race gas in march one year and it was around till november. Come november of that year I set some of the highest MPH passes that I've ever made.

 

Yeah, it will depend on humidity and how well the container is sealed.

 

I would think that a 100% air tight container with an expandable blander system to accommodate expansion and contraction should keep E85 intact for a pretty long time.

I think it is exposure to air that causes E85 to degrade - but I'm not a chemist.

 

I'm not sure on this but I think while metal containers are very good, water can somehow still get to the fuel. Plastic isn't as good as metal from what I recall. My container is stored in a barn and you can hear the barrel pop if it gets really warm our or cools off a lot. Whatever the case put it under cover, elevate it as much as you can, and seal it up as best you can. I'll probably have this barrel around for 2 more months or so, so if anybody cares to how the fuel is running then PM me or something.

 

Metal and plastic are both impervious to moisture. Its the container seal that gets most people. Both metal and plastic containers should be kept in a cool area if possible.

 

So the fact that my containers swell and shrink with temperatures probably mean that the fuel is staying fresh LOL. I went up to the barn the other day to get some reserve fuel and the container shrunk and was triangular instead of a round 55 gallon drum. I'll have to ask travis but I think we got this fuel in late october or early november, so it is at least 2 months old and runs just fine. It'll probably be till feb or march till I kill the reserve barrel, so that should be a good 4 or 5 month test.
