AND....Am I relieved! I tested the 3 old saws I've had for many years, plus the 028 Super I just got, I ran those old saws long before I came to this spot and learned you just HAD to run synthetic oil at exactly 50 to 1. (sorry Gary) I've run EVERY kind of cheap oil (mix and bar) in the 3 old ones for the last 15-20 years (occasional, firewood cutting) Plus (heaven forbid) the cheapest gas available. Never emptied the tanks or ran em dry. Never knew any better! The two old 028's and the 032 tested 160 PSI and the 029 S (ran this one the most) was 150. Not trying to take anything away from all I've learned here....just trying to make the point...old Stihls...must be...tough!
