This is our first year with a house of our own. Thus, it's the first (well, second we had to do a bit last year at both houses we rented, but weren't in charge of mowers or fuel) year we've been doing lawn care. My 50:1 fuel mixture for the weed whacker is just about gone. (Also just about out of gas for my mower, but any left at the end of the season there can just go in my car tank.) So, if I buy more, I pretty much have to do a gallon (unless I get one of those little premixed cans at the hardware store). No way I'm going to use a gallon of fuel in my weed whacker between now and winter. Any chance the stabilizers in the 2 stroke fuel oil mix you add to the gas will keep it good until next spring?
