RE: New Engine Break In
The old Brison company noted 70 or 80-1 synthetic ratios in the manual.
Thats weird, Gregs manual says 64;1 and 100:1, 64:1 being petroleum based oil, and 100:1 for synthetic. I read it myself before I tried it in mine. He threw it down in front of me and said "read it, its right there" and I did, and he was right ! It's the manual that came with his engine.
