Hey 94 Bullitt,
Welcome to the STIHL family. I have 4 STIHL's and wouldnt have anything else. MS251, 038, 038 Super and a MS 660 Mag. The 038 and 038 super have over 12,000 cord each on them, and ive always used STIHL mixable engine oil. Never had a minutes problem other than an oiler pump gears wearing out. I run over the 038 with the skidder and had to replace a handle and a few little parts but they are built tough. My 660 i bought in the begining of February, its cut about 100 cord so far, It was a new saw but i think it was 1 year old, never owned or used. A 2014 model was $1184, i got this from my dealer for $ 600 :cool2: with a 25" STIHL bar and full
chipper chain. The 42" bar from our big Husky fits my STIHL and handles it better too. Good choice of saws .. . John
