It should do depending on who has made it and the quality.  Who is supplying it?

The key issue with 100 biodiesel is the filtering - when you first start using it it will strip out all the *beep* in your fuel pipes leading to your own fuel filter possibly blocking within a tank or two.

Secondly, the supplier I used to get it from occasionally had filtering problems leading to build up of *beep* in the car's fuel filter - as long as you use a decent make of filter and are prepared to change it a little more regularly you should be OK.

Commercially produced biodiesel should be to European Standard EN14214. This sets some quality limits on the oil as a fuel.

One of the problems of producing the stuff is that you have to mix it with caustic soda and meths. If either of these compounds is left in the oil, it can seriously b***er up your engine. The meths reacts with the seals and any plastic bits in the fuel system and the soda can rot the metal parts (steel, and aluminium particularly).

This is why the last step in its production is to mix the new biodiesel with water which dissolves any remaining meths and soda from the oil and leave it 'clean'. You then have the problem of what to do with the contaminated water.

As already noted, the muck in your car fuel system also gets flushed out by the biodiesel so expect to change your fuel filter more often - initially anyway. But also check for water by draining the bottom of the filter regularly because of the risk of small amounts of water left in the biodiesel as a result of its production process.

Most of the commercial biodiesel sellers probably claim their product meets EN14214, but before buying in quantity I would want to know how the quality of the fuel is checked and if the test process is backed up by any independent inspection (if so, by whom).

If this looks a bit like doom mongering, look at the price of a new injection pump and that's just the start of the repair process if the fuel isn't good quality.

If you have a source of cheap used oil and can afford to set up the conversion process yourself, good luck but be careful. If you want to buy converted oil, there are producers around the UK selling in quantities from 25 to 1000 litres and they will often deliver both the oil and a container to store it in. But their price seems to track the price of garage diesel so the cost saving is very small.

I came across this web site listing biodiesel suppliers.

If you are looking for a local supply, it might be helpful.
