This April, I made up a gallon of gas for the 2-cycle weedeater using the cheap oil and used Stabil because 1 gallon can last me more than 1 year on the weedeater. Last weekend I noticed the gas in the tank turned dark. When I was using it, the engine cut out and I was able to restart it and I had no more problems after that. Has my gas with Stabil turned bad? I will note that last year I didn't use Stabil and the gas turned dark and was unusable by the end of the season. I got rid of the gas but re-used the same gas can this year. Did that somehow contaminate this new gas?
