I also did that training course.
Have made a lot of bio, but not to successfully, good enough to run farm machinery.
After many trials found that 100% bio did some damage to "o" rings .
I now run on 50/50 mixture.
still have 3000 ltr of oil to use up yet
Thinking about a Biopro unit. has any one got one up and running in aus?
