Well, have begun my biodiesel experiment in my 200Tdi Disco.
Ran it to just about empty, added 40 litres of veg oil, followed by 40 litres of fresh diesel that I put into some jerrycans today.
Started it up, sounded like normal for about 30 seconds, and then there was a noticeable drop in engine noise, in that it sounds less agricultural, and more refined, right across the engine speed range too. Took it for a spin, and the difference in performance was noticeable too, although seems to have less engine braking than when on pure diesel.
The usual poof of black smoke on startup has gone, to be replaced by a more grey colour smoke.
Smells a bit chip shop mind.
Will see if there is any noticeable difference in economy over the next 2 or 3 tanks of fuel!
