Fuel shelf life
Ive heard that most fuels have a shelf life, is that true? Ive got a never been open bottle of 10% castoroil omega thats about 10 years old give or take a year or so. Im tired of moveing it around and scared to try it and dont know how or where to get rid of it. Ive just thought about trying a tank full on one of my older engines and see what happens.

RE: Fuel shelf life
If you dont see any separations or anything at the bottom of the jug its fine. I have flown some old Omega that the color turned orange form the pink; it was fuel.

RE: Fuel shelf life
Sunlight will degrade nitromethans. If kept reasonably cool and out of the sun, the shelf life should be many many years. I recently used up about a quart of pure nitromethane mixing up fuel that was sitting tightly capped in a cool dark basement for over 30 years. It was still fine when I opened it up.
The methanol and oil components are pretty durable.

RE: Fuel shelf life
Use it.
I to have used unopened fuel acquired in buyouts that is indeed very old and used with no problem. If it presents no runing problems for your engine then there is no reason not to use it. I have also used opened half empty jugs of fuel that was at least some years old and with success.
If you still prefer not to use it then use it in another way, do not discard it can be so useful. There is no better (or safer) engine soak than old fuel to clean up or free up old engines. Also for those times when your airplane may have A noseover/ flopover and the engine gets filthy. Spray old fuel to clean off the inside of a cowling and the engine, works wonders to keep you flying.

I like it when folks think they have old fuel and just want to get rid of it . At 20 + bucks a gallon now , I'll take all the old fuel you want to GIVE me. ENJOY !!! RED

All of what John said. I have used fuel that was over 20 years old and it was fine. It was never opened and in a can, stored in a case out in a garage so it went through a lot of temp changes over the years. I have used 10 year old fuel that was in clear bottles and it had no problems at all. If it works then fine, if it doesn't work then drain it and run some fresh fuel. As John states, it's a great engine cleaner/soaker. It's also one of the best weed killers I have ever used!!!
Asking because I have not found any claim like that on any other webpage. I don't wanna mess up with my garden, you better show any proof or something. Otherwise, it seems like a misleading information.

Are you sure about your claim, Can I also use it as weed killer?

Perhaps you'd best stick with "Roundup" , , and while your at it go find yourself a nice gardening forum to haunt with your demands
