My gas oil mix from last year is still in the can. Can I use the same mix this year? If not how do I dispose of it? Thank you.

I use year-old mixed gas all the time, but I say this with two caveats: 1) I never use ethanol gas, and 2) I treat the gas with Sta-Bil as soon as I get it home from the gas station.  Chainsaw and trimmer are still running great after seven seasons. 

Gas that has begun to go bad has a distinctive smell. If it doesn't smell like dead gas, I'd add fresh premix to it and go to work.   

Back in November, I pulled out my old Jonsereds 670 chainsaw that I hadn't used since 2007.   It had been left with half a tank of fuel in it since then and it did have a bit of bad gas smell to it.  Nonetheless,  I  wanted to get to work right away and added fresh fuel to top it off. The saw fired up and ran/cut fine.   Sometimes you just get luck.  However, I wouldn't leave fuel in a carb with a float bowl.  That's asking for trouble.
