I use Truefuel for winter storage of my string trimmer now. Was not overly impressed with spring start up using my regular ethanol blended gas/oil/stabil mix. I run just enough in the tank to flush the carb and shut her down. These last few seasons she starts right up and runs great. Then I make a 5 liter jerry of gas/oil/stabil mix to last me the summer.
My chainsaw now just uses truefuel as it rips very little every season (maybe half a tank) and I became rather tired of draining the tank/carb for extended periods of it sitting. If I need it for lots of cutting then she can get the gas/oil mix.
I will be running some truefuel in my old Lawnboy hand held blower this winter as I will store it inside and run it occasionally to dust off the snow on the sidewalk.
