It actually has some inadvertent water content when you buy it, albeit a small amount. The C of A I get at work (wholesale) when it is distributed to our facility lists water as apart of its contents. From there, I suppose it just compounds over time and exposure.

Fortunately for me there is an e85 station within a mile from my house, unfortunately It's in Boston so for me to get there at 5 when I'm out of work is hard sometimes so I will be storing some too. Anyone think a dehumidifier will work next to the E? I won't be trying it sense I won't need to store it long but maybe worth a shot for some of you that are far from the station.

I was worried about this @ one time as well. I still try to elevate the stored e85 containers and keep water away from them, but read it is not nearly as big an issue as originally thought.

If you google e85 storage, you'll catch a few links to many of the evo guys discussing it. Some have stored it for a LONG time and still had it test as if it were new.

One person made an interesting point about how long it sits in the rail cars as well.

I've personally used e85 that was sealed in a gasoline can after 6 months of storage with no issue.

Once I read some of the storage stories on the evo sites, I felt a lot more comfortable about storing some in sealed containers.

I put my 3 gas cans on the middle shelf in my garage, and I get nervous if it stays there more than a week lol, 6 months is crazy I guess I need to relax a little haha

Have you seen any issues of storage when it becomes much warmer out? I live in So Cal, I mean it can get up to 115 here, garage turns into an oven at that point. My nearest station is about 30miles away, so I'll have to be store 15-20 gallons at a time since I commute and use the car as a DD all the time. Plastic containers aren't ideal, id Prefer to get my hands on a 55gallon drum that was previously used for fuel like a VP container.

Any insight would be great :)

Has anyone actually had any issues storing E85 for long periods of time? I keep reading posts that sound like this: "I wouldn't store E85 for more than XXX." Now, don't get me wrong, I like scaring myself as much as the next guy, so I read all of thee posts and they make me very nervous about that can of eth that's sitting out in my garage.

But, I think a more helpful post would be: "After 9 months of storage in a 5-gal steel jerry can, I took a sample of E85 and found that it had X% water in it," or, "My E85 phase separated after Y months in a plastic fuel container." Can anyone contribute anything like this?

Intuitively, I can't figure out how a sealed container of E85 absorbes very much water after it sucks whatever residual vapor was in the small amount of air that got sealed in with it. So, it _shouldn't_ be a problem unless you open up the container frequently.

For the record, I use 3-gallon Rotopax to store E85. That way, I never have to measure anything. Plus, Rotopax are really expensive, and I love spending money.
