TBS
I have chainsaws and chainsaw accessories.
Heat is the biggest enemy for fuel. I had 5 gallon jug that was over 2 years old stored in a shed next to a 250 gallon water tank that never gets over 75 degrees inside at our cabin and it still smelled fairly fresh and my mower ran great on it. At grandmas in fresno it gets over 105 in the summer I would drain the tank on my grandpas riding mower every two or three weeks because the fuel with stabilizer would go stale which made for lots of fun when the carburetor would plug and I have to pull it off to clean it (v-twin b&s have lots of parts around the carb). fuel came from the same station.
