I was down at a local oils supplier today, Ovoline in Gateshead, buying lubricant for my diesel generators and I noticed they did chain saw oil. But, not only this, they do a 'Bio' chain saw oil made from recovered vegtable oil. So, if you are a fan of chain saw oild but don't fancy spreading mineral oil all over the roads and tracks then pay Ovoline a visit.

Smallprint: bio chain saw oil may be available from other suppliers. The price of oil can go up or down, usually up. I don't work for Ovoline. Etc. --
