I do not use trufuel except to break in a new 2 cycle engine. I do however use non ethanol fuel mixed with oil at 40 to 1 to winterize all my stuff. On my zero turn I also use 40 to 1 mix. Oil in the gas gets to places it can not with just gas. It is such a small amount of oil I'm not sure it really does anything but I have done this for 30 years and I'm not changing my procedure. It works for me. I fill all my equipment to the top every time I turn it off for the season. More fuel = less water( condensation ) in my opinion. All left over fuel in gas cans goes into my truck. Premixed and all. Fresh gas for the new season.
