I have a gifted Husqvarna chainsaw, a Poulan Pro pole-saw/trimmer, a Ryobi trimmer, a gifted Hitachi blower, a very old not-so-used gifted Weed Eater hedge trimmer, and a well-used McCullough chainsaw, that are all still going strong. I've also had 2-cycle off-road motorcycles: a Yamaha, several RT340 Rokons w/ Sachs snow machine engines and variable-speed centrifugal drives, and a MX250 Husqvarna. Also, had a 3-cylinder Mercury outboard. All preformed well w/ whatever 2-cycle oil was available in gallon size at Walmart. I used gasohol at the recommended oil/gas ratio in them all.
I had a couple of 6-gallon boat fuel tanks w/ mixed gasohol that I didn't have an opportunity to use. After about 7 years, I used it in my small-engined equipment w/ no negative effects. I've heard that 2-cycle oil can stabilize gasohol, and it worked well for me. The tanks were sealed and stored in the covered trailered boat or in a large unheated metal building.
