. Always use non ethanol fuels, either remove the ethanol yourself or purchase the premixed non ethanol 2-stroke chainsaw fuels. These fuels can be stored for upto 5 years, compared to 4 months for ethanol fuel. And the additional lubrication in these premixed fuels benefits your small gas engines.
In the case of the Stihl 600 PW, Stihl sells stabilized 93 octane ethanol-free 4 stroke fuel by the gallon container. Purchase one at the time of PW purchase and they double your warranty to 4 years. For my limited use 2-3 times a year, I'm OK paying the premium all the time to know the fuel is good.
