Chainsaw Bar Oil Question

So, I was talking to a buddy of mine tonight. Asked him the same question and lo and behold, he's worked for an arborist (of course he has, dude changes jobs like I change underwear) and said that the entire time he worked for them, they used canola oil.
He said its sticky, it the right weight, and it's eco-friendly.
I'll give that a try I guess.
