Is there a spec yet for biodiesel made from waste vegetable oil.?
Answers:
Have a look here they show you how to make your own biodiesel

Yes, all fuels and oils have to meet certain criteria from the API (American Petroleum Institute)
Yep there certainly is key in the word Biodiesel on the web and the world is your oyster, you can even buy the filtration kits!!
www.hydrotechnik.co.uk may be a good place to start.
go to a bio fuel dealer or website ( google search ) but as far
asi know there is not and as long as you do not pay for the fuel you do not have to pay tax on it ! so if you have a friendly Indian take away who would love give you his old oil then away you go, the best cars to use this can of fuel is a Mercedes apparantly accoring to car mechanics mag, but you must change your fuel filters more frequently, it would be best if you sieve the oil through some very fine mesh to get all the bits out.
