Forgive me for this but...
Any of you lot using bio 2T oil in your saws?
There's a business about an hour away from me that specialises in bio oils for many different applications. They have three different bar oils and, what was a surprise to learn, a bio 2T oil that meets the ISO/JASO FD standard and gets mixed up to 50:1.
Keen to learn if I should try it when next run out of 2t oil.
Their bar oils have been proven in recent studies to result in statistically significant bar temp reductions compared to synthetic/mineral bar oil (I don't know what type). Temps are one thing, and it's nothing those of us that use canola don't already know, especially given the better specific heat qualities of canola/rapeseed oils, but the study showed a temp reduction even at half the flow rate of the synthetic oil. Friction is one thing, but chain slap and bar wear is a different animal and there's no way I run my oilers at half rate. Lower temps are great but the bar wear would be massive. As usual with many such studies - they leave more questions than answers. The trial was done with 10 foresters over a month so they could have easily measured bar wear in addition to temps. That they didn't or those results were not readily available makes me go hmmmmm.
After some digging it appears to be made by a Czechen business that does all sorts of bio oils and plastics. In Europe, branded as Biona or Bipol, and outside Europe as Lubeco.
pretty nice out now though 
Files were here when I woke up this afternoon. Can't wait to get after it again.
it was 10 ° when I left this morning
I just got done with a load of maple about 1/4 of the upper part. Blow down about two years ago. Not used to old school splitting by hand. Tomorrow I use the trailer and winch
