Introduction
Some winter fuel additives were tested with Biodiesel made from a mix of soy/rape. Drip cup tests were performed to assess viscosity (times are in seconds - smaller times have faster liquid flow and therefore show less viscosity).
This Biodiesel starts to gel at -1C and at this temp the drip cup test is 23.3 seconds.
Many thanks to K.H for performing this testing.
