How long will glow fuel last?
Forgive me if this has been asked before but how long will glow fuel stay good for usually. I've got a jug that was opened about 2 1/2 years ago and has sat unused because I wrecked my plane. I finally got a chance to put another one together this weekend and I need to know if I should be expecting to make a trip to the hobby store before I try to test run the engine.
