A co-worker of mine gave me two unopened gallons of glow fuel, that are several years old. It is Tower Hobbies tower power fuel, that is green in color, has only a sticker on it that says 10% , and was used by a relative of his who was into r/c cars. I'm assuming the 10 % sticker refers to the Nitromethane, but I have no idea what the percentage of oil is inside. Is this stuff safe to use in my Hanger Nine trainer with the Evolution engine??? or could the oil level be too excessive or too low to use in my plane..Let me know if you'd run it or not. By the way it was always stored unopened, in a dry dark place.......Thanks.
P. S I have only run Wildcat 10% nitro 18% oil content in my plane so far.

Yep it should be fine as long as it's not cloudy (water in it) just about all 10% nitro fuels are 18% oil or more

Thanks for the info, Woodman.
