May as well add my Two pennies worth on this subject as i used to make it, and probably the best bio diesil in the country as well. Goverment says water content should be no more than 500 parts per million, i got it down to 62 parts per million. I made all my bio diesil from used cooking oil which has no other use except for going into landfill. The water we used for washing it was used in a solution with an organic aphid killer and the glycerole was used to make soap, shaving foam and could of been used also to make dynamite.
The trouble is that there is not enough goverment help for these bio fuels companies. The farmers also are not allowed by European legislation to grow on all their ground and they get paid by the European Goverment not to farm a certain amount of their land every year, this is called 'Set Aside'. However the farmers are allowed to grow crops such as Rape Seed. Most of the British Crop actually goes to Austria which is crushed and used to make Bio Fuels. The solid part is given back to the farmers as cattle feed. There is a bio fuel plant in France which will use the useless parts of slaughtered animals and turn it into bio fuel. Tesco's have booked every minute of every day in the U/K's largest Rape Seed Crusher in Elesmere Port and have their own bio fuel plant at Immingham, Humberside. I believe that they are using it solely at the moment for their own vehicles. All Diesil vehicles can use the alternative bio fuel, the reason why some vehicle companies say no is because they are tied in to the big oil companies. If they said that it would be fine to use it they would not get cheap oil based products from companies such as Shell and Texeco.
Bio Fuels will be the future like it or not.
