Absolutely great running little saws. Bought one from my aunt when my uncle passed away a few years ago. It's probably 15 years old at least and still runs fabulous. Use it more than my MS361. You will love it! I mix all my Stihl's 40:1 with Amsoil Sabre oil. One of my buddies who has been a Stihl certified tech for 25+ years says that he runs all his 40:1 and has never fouled a plug and never burnt one up. Oil is cheap insurance.
