need a new chainsaw

Just in case the dealer didn't tell you, never, EVER use motor oil for the chain. Use only bar and chain oil. Motor oil will burn up your bar and chain so fast it ain't funny. Bite the bullet and buy a 6 pak of Stihl 50-1 mix to make your gas with. Congrats on your new Stihl saw. I have 2 Stihl saws that I use for firewood and storm clean up. I've had them both for years, and take care of them...but don't baby them. Neither one has ever let me down. If you don't already have them, get some chaps, safety glasses, and ear muffs.
