Are you referring to Trufuel? I've seen that sold at Lowes and I've been purchasing the slightly more expensive Stihl Motomix fuel. I don't run my saw on this fuel while cutting but when laying the saw up for more than a few weeks I drain the gas, run the saw until it stalls, add a little Motomix and start saw to circulate through the carburator, shut saw off. Trufuel and Stihl Motomix come from the same factory with Motmix using Stihls HP Ultra synthetic oil. Trufuel does claim to use synthetic oil so I'm sure it's just as good. The nice thing is that the shelf life is 2 years for either fuel and it's ethanol free.
