I'be been looking into the biodegradable 2 cycle mixes and b&c oils out there (arboroil, green earth) and was wondering what your thoughts on these were.
Bar and chain oil maybe, but not 2-stroke oil. That's just me though. Make sure you drain the oils out when done, I believe it tends to gum up after awhile.
I would not run anything through my motor except Hi grade real Oil sucked from the ground. The enviroment will benifit because you saw will last 30 years instead of blowing up every year or two and causing more saws to be built. Oh yea, you pocket will be alot greener too not haveing to replace saws.
