So you guys just put new veg oil straight in the tank and have no problems then? I would have thought some kind of additives would need to be used or am I wrong if I am il be use veg oil very soon

i prefer to run in through a 0.5 filter before use just incase as it doesnt take much to clog a diesel filter

Neat veggie oil will knacker your injection pump up. Look at the side of a chip pan for an illustration.
 
filter it well you dont know how much it been filtered down to at the factory and whether or not its been sat in a cold area and always best to mix it with diesel

Filtering only helps on WVO, the problem with all veggie oil is the glycerides in it. It really needs to be converted to bio diesel, even then care is needed.
 
The SVO that I buy is (food grade) rapeseed oil. It is a "soft" oil similar in characteristics to sunflower oil. It does not need to be filtered. Just mix it 50/50% with diesel. Avoid palm oil which gels at low temps and you will be alright. I have examined the fuel filter on mine closely and there is nothing there. Even so as a precaution I change every 6000 miles. Using WVO would be a different matter. You wouldn't know what was in it.

The M51 indirect injection engine and the Bosch FIP is perfectly happy to run on 100% veg oil if it is heated up to lower the viscosity. All this is old hat though. There is a lot of past experience documented on BMW forums.

Other engines and injection pumps do give problems on veg oil, particularly modern direct injection engines and also Lucas and CAV pumps. That is when biodiesel must be used. It can be used but is not essential for the p38.

Pure veg oil will lacquer the internals of your injection pump and cause failure. It MUST be mixed with diesel/petrol/paraffin to provide a washing agent.
