I had issues with my snowblower last year, issues like keeping it running. Dude at the shop told me that small engines don't like the ethanol in the gas because it evaporates faster and gums up carbs in engines that aren't run daily like your car. He said he tells all his customers to put Sta-Bil in the gas ALL the time, not just for storage. Haven't had any problems with the snowblower, mower, or weed whacker since. Also I see that Sta-Bil now has a straight ethanol treatment.
