RE: best oil to use
Best oil, wow what a question. Even though I use Red Line mixed at 32:1 most any oil designed for air cooled 2 stroke engines will work well in our relatively light duty engines, but since we generally want the best for our little jewels some of the better known quality oils are, Stihl Ultra, Red Line, Pennzoil, Royal Purple, Lucas, Mobil and Bel Ray to name a few.
