I put StarTron fuel treatment in my gas cans before filling them with ethanol-free gas. StarTron was the only fuel stabilizer we used at the lawn equipment shop I used to work at. Service manager and lead mechanic said it was better than Sta-bil, so I used it in all my equipment during storage, and never had problems with starting my equipment afterwards. Gas with ethanol added is a repair shop’s best friend, as most of the no-start issues were due to the customer using gas with ethanol. When you recommend what gas to use, some will listen, but most will not.
