Default Fuel Life

How long does fuel keep for?
I just recently bought a nitro rc and still had fuel sitting in a box in the back of my cupboard for about 1 year. Took it out today to check it and the color is still fine and there is no droplets etc. inside the bottle. Would the fuel still be fine to use?

the longest period that I stored my fuels is for 30 days, if I don't use the gas for 30 days I change for new fresh fuel.

...........fuel is hygroscopic.........absorbs water when exposed to the air....too much water in the fueland it won't burn properly. water in fuel will rust the steel parts of your engine........

Hi,
Well stored fuel can last for several years. If it's in a plastic bin, squeeze the air out, put it on a shelf that is not on the floor and out of direct light.

Have ran some BK fuel we had for 5 years in our regional last year... almost won the thing, and ran times as fast as anyone.....

keep it sealed, keep it cool and dry, and out of the sun..... and run it.......

Thats a little extreme. Fuel can be stored for a very long time as long as it kept cool and dry and out of the sunlight. I would run the fuel and see how the engine runs; if you can't obtain a decent tune, then I would purchase new fuel. But I've kept fuel up to 6 months (the off season)and it still ran fine.

I have run fuel that is over a year old. Like said earlier, try it. If it won't run right, then get fresh stuff.
