Good Grease

Hi
From good old germany.
I run all my cars actually two VW TDI´s on pure plant oil (selfpressed rapeoil) since 1999 (50000mls/year). Your problem might be the filtering. No Filter bag although it ist a 5/1 micron bag do it like it´s discribed. The productivity is between 50 and 70 percent, so thats bad and your problem. If you use selfpressed oil or WVO (Biodiesel is the worst) you`d have to let the oil in the container for at least 2-3 weeks (depending on temperature and viscosity) without using the oil, than pump the oil from the top (because of cleaning the oil by sedimentation) through your filtering bag with a pressure not acceeding 1 bar.
If you just started veggie fueling, a cleaning process of all of your fuelsystem will take a few full fuelling processes. Veggie oil cleans the pre diesel used fuelsystem and the otherway round diesel cleans a veggie oil system, so that sometimes clogged filters occure.
And make sure that there´s no water (humidity) in your oil.
At your speeds and rmp´s (in US) you drive on highways, the high viscosity of the oil should be ok for delivering the oil through the filter to the injection pump.
So don´t be a fool and stop your usage of plant oil.
