Chain oil alternatives???

Used oil called Plantoil on a job near river about 5 years ago with no trouble when changing back to what I use normally still got some kicking about in a can some were.

Just use 10-40 motor oil in mine over the cold weather.

For years now I have only ever used bio oil, not experienced any problems with it. I was using Buxtons own brand which was good, then tried 20L of Oregon Bio as cheaper. Lots of gloop in the bottom of the container, so never used it again, went back to Buxtons brand.

For the last couple of years I have been using Stihl's own brand of bio, more expensive but I trust Stihl's judgement. Also bio oil pours much better in cold weather than mineral oil.
