What he said. I have 2 Stihl chainsaws and Stihl weedwackers. I have a 14", 16", and 20" bar and chains that are interchangeable. All run on the 50:1 synthetic oil. I started adding Stay-Bil marine formula to all gas tanks I now fill. Never have to remember whether I have winterized anything or not. Small price to pay for not worrying about fuel problems.scalabro wrote: Sthil MS270 Farm Boss, the perfect homeowner saw.
My brother owns a few NAPA stores. They have just converted the Reading, PA Fire Company over to the ethanol free pre mix fuel mixture for all the fire dept. gas operated tools. They had been having problems with stale fuel since they might not be used for some time but when they need them, they need them to fire up right away. Costs a bit more but peace of mind prevails.
