This is from Sylvain Purtell:
I running my TDI 2000 with wvo, soy and canola, donuts...
I run 20 000 km and run very good.
I'm from Montréal, Canada, Québec.
The setup it's the same that Greasecar, 6 ports to switch between diesel and
oil and 3 ports for backflush feature, Aluminium tank with coolant heat
exchange, I use a Greasel Triple-by-pass hose to heat a line of svo.
It's expensive, but it's a very good product.
I use a 10 micron , heated, spin-on fuel
filter, 1 micron FSI filter bag for pre filtering.
The setup is like a Greasecar.com with a backflush feature to purge a filter
and a line of the svo with diesel before shutdown. It's the best setup I
found for a cold weather.
