My car is running E85 and I might need to storage it for this coming winter.

One of the things to winterize a car is to add "Fuel Stablizer", but is it safe to add that additive to E85 gas??? Anyone done that or had any experience with such??

 

e85 will turn to water pretty quickly. ive had some thats sat from a tuning session for two weeks in a can and was ****. put it a lawn mower and used it up lol. i recommend starting the car every other day and fresh corn come spring with the old drained. Some of my friends have had a car down for about 2-3 weeks and the car will just break up and sputter when its running again till the "old" crap is burnt off.

 

If the e85 does turn into water - that's very scary Maybe I can switch the map and fill it up with 93 gas + stablizer for the winter. Then when spring comes, drain it, switch back to e85, fill it with fresh e85, Boom to go!! Would it work better that way then??

 

just drain the tank if you're planning to store it. on typical cars you can leave gas in it and it be fine, but you have a finely tuned STI killer. Keep it safe and just drain it.

 

I would have to agree with the draining idea. No point in leaving it just sitting there.

 

I have stored my E85 DSM all winter long with E85 in the tank. There are numerous methods people say, some say make sure it is topped off as much as possible. I personally put topped it off at the closest station and added some fuel stabilizer in there an left it sit in storage from December till March. I took the battery out so I never started it. Spring came and it fired up like it normally does. I had an anodized fuel rail and cleaned the injectors once a year anyway. I have never drained a tank. This was my experience with E85, so just giving you another perspective, not trying to start an argument. It you could drain it and run it dry you would not have to worry.

Putting it in a lawnmower probably caused more damage to the mower engine than leaving it in your car would. Lawn mower engines were not designed to handle E85, especially if they have an aluminum carb. The mower probably ran like crap since most likely would need a new carb calibration. Plus if you let it sit in there it would start pitting the aluminum and degrading the o-rings and such. It could actually form a gel like substance and clog jets.
