gas stabilizer ???
I keep Stabil in every gas can for my small engines, I also mix it with high test.
I have about every small engine know to man, chainsaw, pressure washer, snow blower, lawn mowers, weed eater, leaf blower, wood chipper, 4-wheelers, hedge trimmers, etc.
No matter if they have set for over a year they start.
Do not run it out of fuel, it will suck all the dirt from the bottom of the tank.
Fill the tank full before putting it away.
