Bio diesel is processed vegetable oil there is nothing from crued oil in it. There's a place in York that sell it. Or its made from new rape seed oil. Its Cetane rating is lower than pump diesel. Full on bio diesel is'nt sold on major filling station forecourts.
You mean that one on the A64 opposite the Highwayman cafe? If so, it shut down when the price of diesel dropped 30p a litre, at the back end of last year. The bloke told me they were carrying on producing bio in small quantities and stock-piling used oil, just not selling the finished product. I used quite a few tanks of it in my Mondeo 1.8 TD after the price of neat veggie oil went up, I was running 50:50 on veg and pump diesel, veg @ 50p a litre and pump diesel at £1.28 a litre. Worked out about 40p a litre saving over normal pump diesel, plus the car felt torquier and smoother at lower revs, although it didn't rev past 3k rpm as well as on pure pump diesel. When I went over the to the bio diesel it felt just like pump diesel really. 50:50 veg & pump diesel would kill a JTD quick though.
You are obviously aware that biodiesel eats away at your rubber seals ...
Correction, the methanol used to thin out the purified veg oil eats away at your pump seals. @ what percentage methanol the pump seals start to die is another question entirely..
My 2.4 JTD is a 2003 model interior face lift, what I have noticed that there no cloud of black smoke when I boot it
Economy seems the same so far. It was 62 litres for 49 notes
The smoke will be a lot lighter in colour, but I think it will still be there. Noticed this on my Mondeo with veg oil, it still smoked but the smoke wasn't dark. The only time it smoked more was on start-up.

Interesting, read this ages ago when I still had my JTD
