Low sulphur diesel has reduced lubricity and can affect the longevity of your engine. Even 2% Biodiesel will provide increased lubricity needed while not affecting performance.
The real issue with biodiesel is the gel point temperature. The higher the percentage of Biodiesel to Petrodiesel, the higher the temperature at which the mixture will gel. If you are in tropical climes, this is not an issue. However if you operate in colder weather it can be a significant problem.
Biodiesel burns cleaner than petro diesel in all contaminants expcept NOx. As long as you don't go above 20% Biodiesel to Petro diesel mix, you should experience no significant loss in power, no gel problem and the motor will run cleaner. Engine manufacturers are reluctant to recommend more than 5% micture of Biodiesel to Petro diesel, due to potential damage to the injectors.
One note of caution: Biodiesel acts as a detergent, and will clean the crud that may be in you tank and lines. For the first few tankfuls you may have to clean your filters more often.
Pure vegetable oil is NOT biodiesel, however it can be converted to Biodiesel. Pure Vegoil can be used to in place of diesel, however this will require some modifications to your system. The gel point fo veg oil is very high in comparison. Cars that run pure vegoil require two tanks, one for petro diesel and one for vegoil. The vegoil tank and lines require a heater to ensure that the vegoil doens't gel. The process requires starting the motor with petro diesel and switching to vegoil once the temp of the oil is warm enough. Before shut down, the fuel source needs to be switched back to petro diesel so the fuel in the lines doesn't gel.
Hope this helps. There is a lot more info available on the web.

I recently saw a brief item in the July Seaworthy magazine, which is a publication of BoatUS to the effect that, after conducting their own evaluations of biodiesel, both the US Coast Guard and US Navy have decided that they will not use biodiesel in any vessel that could be called into a critical or emergency repsonse. Their concern, according to this article, was their finding that the stability of biodiesel under marine conditions was significantly less than that of diesel fuel. If I can locate the actual article or a link to it, I will post it.

Check out www.biodiesel. org/ there is a wealth of "solid and well found engineering advice' to recommed
blending Bio into your tank. The results are far from "unexpected" .
