ive been using a squirt oil can, seems to work better than the gravity feed system.
standard bar and chain oil.
the canola oil is crap, thought id be more helpful to the environment... everywhere it has dripped ect, its now like the kitchen stove was, this yellow sticky caked on crap that dosnt come off, and it dosnt lube very well either, back to standard bar oil, seems like the chain isnt as gummed up either.
Im currious to try a water drip in the near future, when i was slabbin or usin a chain saw to cut frozen logs, seemed to stay fairly clean. Now its warm out, oak seems to be the biggest one to gum up the chain.
