I think you would need to pass the veggie oil through some sort of process to turn it into biodiesel. I know I did it in college, and am pretty certain it would run on it, but I cannot remember exactly. It would very likely not burn as clean, and it would lack the additives that are added to comercial diesel fuel from which the engine benefits.
Check out www.greasecar.com they have a kit that can be put in any diesel car that will allow it to run on veg oil. Even if you don't want to buy the kit the message board there is great and will answer all of your questions.
From what I have read veggie oil is cleaner burning than diesel because it contains no sulfur. It also provides the same power and mpg and costs a lot less. (Free ) Because of the lack of sulfur the emissions are quite good as well. Your diesel should have no problems running it, I'm sure there are quite a few people over at greasecar who can show evidence of this.
The cost of properly produced commercially available propriatory fuel even at present prices is "nothing" compared to the real costs of running the car-----properly. Let the "experts" try out cheaper fuels & save your own car for yourself. I'd run mine on water or even sewage if it were properly proven to not destruct my engine. Meanwhile I'll pay the regular pump price.
I'm pretty sure biodeisel is perfectly safe to put in your car. However, I don't own one and have never tried it, so don't take my word for it. Everything I have read on it, though, had good things to say. And I did do quite a bit of research when I was bimmer shopping, as I was considering a diesel.

I love people like you. You're the reason car dealerships are able to charge 200-1000% markup on most items. You'll pay whatever we ask because you haven't done the homework yourself on how things work/how much they cost.
You can run pure veggie oil as long as you run an inline filter and the oil is heated to around 170+ degrees F (otherwise the viscosity is the main reason it wont work) There are additives out on the market which lower the pour point of oils to make them not need to be heated but they are mostly alcohol based to my knowledge.
Vegetable oils have about 6% less BTU's per gallon then diesel (136,567 Btu/gal vs 128,372 Btu/gal), so you can roughly expect a similar MPG as diesel.
Interestingly, the cetane #'s for vegetable oil vs diesel is also favorable in the the avg cetane # for veggie oil is ~35-45 vs ~60 for diesel.
Old seals on vehicles made prior to the introduction of viton seals (around 1993) can have seal failures though, as a side note.
