I see bio-diesel as the FAME, as that what it gets referred to at work.
There's all kinds of different shit gets made into "bio-diesel", animal tallow, rape seed etc etc. It's just a matter of refining and purifying it.
As said, as far as I know and is the general knowlege over at the veg oil forums, well made biodiesel is fine in any car. I haven't heard of any issues with good biodiesel anyway. And it's usually just as thin as diesel, most the time a little thinner too.
