old fuel?
i ran across some glow fuel i had from when i used to fly with my dad, so it's at least 11 years old. i was wondering if i can still use it or if i should just get rid of it. what's the best way to get rid of it if i can't use it?

RE: old fuel?
I have a question reguarding old fuel myself. not unopened fuel that has been stored properly but, fuel that has been opened and say carried over the winter. When I open a new jug of fuel I put my pump on it and don't change it until that jug is gone. That being said, the last two years I have had to replace bearings in two engines An OS .91 FX and an OS 46 FX. I fly during the winter when weather permits, usually 3 or 4 times a month. On each occasion the engines started running poorly on the old fuel but would run fine on new fuel. Being somwhat tight wadded I didn't discard the old fuel but chose to burn it up. My question is could the old fuel accumilate enough moisture to cause the bearings to rust but still run in the engine. I always run the engine dry after a session and add a little air tool oil for ARO. I'm sure I didn't experiance a lean run. There was rust on the bearinga and crank shaft. My shop is not climate controled unless I'm in it, so the stored fuel goes through temp changes. In the spring and summer fuel don't last long enough to get water in it.

If it is dark brown in color I personally would get rid of it.

im guessing that if it will run in a engine (aka burn, last time i checked water doesnt burn very well
) then theirs not enough water in the fuel to do damage.and how often did you use the engines? after run oil them? keep them out of the humidity of the summer? could be a lot of things.
i would use the old fuel, but thats just me. i would also run it in spad's and older engines, so that way if the engine did die on me and i were to have to deadstick in a awful spot. a spad wouldnt care to much

RE: old fuel?
Both times it happened it was winter or just comming onto spring so the summer humidity wasn't a factor. I would run the engine dry and apply about a teaspoon of after run oil and give it a quick spin with the starter at the field after each session. As far as using the engines they would get used 4-3 times a week during the summer with no problem and maybe once a month during the winter - as weather permits.

RE: old fuel?
Because you live in a humid area the slight rust problem may always be a bit of a problem?? As to the fuel working during the summer but not in the winter did you fatten up the high end a little?? As the weather here starts to cool down from about 100 and it gets to the 50s I have to start opening up the high end a bit at a time. From summer to winter all my engines have a four click difference on the high end or they will start going dead stick on me. It's not a problem with my fuel.
