If you have a lot of work for your chainsaw, it is good to know how long you can run your machine before you have to add gas or change/charge the battery. STIHL claims a forty-five-minute runtime with a chainsaw and battery, but it is hard to equate what runtime minutes mean with a chainsaw. If you want to store your chainsaw for a long time and find it seeping oil for many days, then the problem is with the vacuum relief valve.
STIHL MotoMix has a 2-year shelf life once it’s opened, and 10 years unopened. No mixing is required as MotoMix is a 92 octane premium fuel 50:1 pre-mix! If it is a chain saw you’re using, ensure that you have filled the bar oil tank with bar oil. Stihl Ultra is excellent oil, use it at 50;1 with confidence.
Ryan,For many years, I never put any fuel stabilizer in and the saws were fine for the winter. Over the last few years I’ve been putting in a few thimblefulls of stabilizer in the fuel tanks of my saws when I put them away from about Dec. 1 till about Apr. I run the saws for a bit after I put the stabilizer in and at the same time I run some fogging oil through the carburetors while they’re running so it gets real smokey.
