I've been doing that for the last few years..This year I decided to stop buying gas and mixing it for the 2-cycle engines. I use them so little, and they foul so quickly, and the gallon of mixed fuel can sit forever before I use it. Even with stabilizer it gets old. Decided on a whim to get a couple pint cans of alcohol-free pre-mixed 40:1 small engine fuel. Much easier.
