I have recycled cooking oil on my list of future enhancements to my Tdi300. I have decided not to make my own Bio, as dealing with some pretty nasty materials etc in residential area probably not recommended... plus the health & safety concerns. Basically there does not seem to be a problem, starting and stopping on Diesel, and when it is warm, running on cooking oil.
Have a look through the Yahoo BioDiesel groups, I think there are Tdi300 users in Sydney, I'll have a look through some of the stuff I have collected on the subject, and PM you contact details.
