Derby or Burton area for biodiesel???

I'm wanting to fill my disco up with 100% biodiesel, after i saw a post from charlesY, giving advice to someone because they had trouble with black smoke. I just wanted to try 100% bio as charles suggested. I'm strugling to find somewhere in derby or burton that sells 100% anyone know of anywhere?

If i have to settle for 5%, will it make much difference to the black smoke?

Thanks

try this Region 4

Yeah that's a great help thanks, i went on that site god knows how i bloody missed that!
So thanks for that, It looks like the last 2 are about 45 mins from work, i'm waiting for the first 1 to reply to an email.
If anyone else knows of anywhere nearby that would be great.

Thanks

Sorry I couldn't get any closer than that, 45 mins isn't too bad.

Well went to the one in Stoke in the end. seemed pretty good to deal with. Yeah not to bad travel wise, just a pain if i want to fill up with it every week! So thanks again.

Still keeping my eyes open though just in case.
