If it's clean, unseparated and free of water I mix it with a tank of fresh and burn it through one of my vehicles. I don't like to run old gas through my small engines, I only feed them good stuff. Otherwise, I mix it at a ratio of 1 part gas to 3 parts diesel and use it for burn fuel. Or, as recommended, it can be taken to the borough landfill for disposal. (It's free).Just mix it in with fresh and burn it through?
Absolutely! Safety is a must!HINT: Be careful if you follow the burn barrel advise above. Even a small amount of liquid gas can produce a lot of vapor and a HUGE fireball when you toss that match.
I'd feed it to my Tacoma. I do same annually with my saw gas if I haven't been running it much, and I mix a fresh batch for the saw.So I ended up with about 2 gallons total. It is definitely a pre mixed gas, but there is no separation and appears to be clean.
