Todd,
Fits well with my experiences and therefore I said before, "I also use the manual feed button on the chain saw frequently to give it some extra cooling and lubrication. Do clean the blade carefully directly after use, which you always should do anyway. Veg oil do create some minor cleaning problems, if you let it cool down." Nice to have a better explanation, because the gum residue get mixed with saw dust. It is no problem normally, but if I am lazy and do not clean directly after use. I have to work a bit more before I use the saw the next time. Maybe you can help me Todd, I got some responses and statements from Rod Stalenberg. It turned out that he works for BP. I responded and it took some time before I discovered that it was not a list discussion. He claimed that it was no difference between veg oil and fossil oil and that both was comparable in poisoning the nature. Since I am not an authority in chemistry, I asked the list to comment my discussion, but have not yet got any answers. Personally I belive that this is not the case, all I read and heard, points to the opposite. I am once more copying our discussion at the end of this mail and would be grateful for comments.
