They are just a lot easier if you are just cutting a few limbs. No gas
problems. (mixing fresh, using it all or dumping it etc)
I keep about a quart of gas/oil mixed for my string trimmer, which I use
at least once a week. Same mix goes into the chain saw. Stays fresh
enough, or at least it's never given me a problem. When I am finished
with the chain saw, I empty the mix out back into the little container
and run the saw dry. I use the chain saw about once a month for cutting
limbs too big for the Sawz-all.
