I was lurking on an Arbhorist web site this past summer where guys were talking about using vegatable oil for bar lube. These guys use chain saws for a living. Very serious crowd. It seemed that over half of them used the veggie oil for bar lube with no adverse (equipment) effects. Most switched because of their wives complaining about the oily mess and smell on their clothes. I did not like the idea of spreading motor oil all over my property, so I thought I would give it a shot. After 4 months now, all I can say is that I will never go back to petro for the bar lube. The odd thing is, my saw is starting to get cleaner, the more I use it. I can sharpen the chain without my hands becoming an oily mess. The chain still has an oily coating on it. The chain also seems to run more free with less gumming. I see no evidence of premature wear. Anybody else use the veggie oil? If not, do our environment a favor and give it try. I'm convinced.
