I've taken to using the TruFuel product for winter storage of my Echo leaf blower and weed trimmer (even though the blower gets occasional use in the Winter).
For the Toro snow blower, I have always just run it dry and then stored it in the mini-barn. This past Spring I decided to put in some TruFuel and store it. Turns out that wasn't a good idea. Not only did all the TruFuel evaporate in the warm summer temperatures, but whatever the oil they use remained. I couldn't get the thing to start until I realized the tank was dry, then when I added some mixed gas it was very difficult to start (unlike it ever has in the 15 years I've owned it). Once started, it blew a lot of smoke until warmed up (or burned off). After the that the thing starts and runs normally (with the gas/oil mix).
Since the TruFuel smells like solvents, I suspect it evaporated in the hot shed during the summer. Needless to say, I won't be using it for storing the snow blower again. I'm curious to see how it does in my chain saw which gets very irregular use.
