Lotta people having to replace wrist pin bearing, lower rod bearing, and main bearings. More oil when jetted correctly is gonna reduce wear.
My younger brother is a concrete contractor(took over my business in `89). He keeps a Concrete Partner saw. Very dusty work, a lot of strain cutting that concrete with the 2-stroke engine.
Always used 50:1 and had to replace his saws often. I told him 32:1 would keep his saw going a lot longer.
After a few years he told me that it made his saws last WAY longer.
You can run WHATEVER. I will run what never makes me tear one down,cause I like long rides,trouble-free.
