Freelander TD4 and Veg oil

[stephen]

As its been supper warm I thought I would try a drop more veg oil in the Landrover 75% ish.  It protested by not wanting to start  5-10 cranks so I think I have found 50% as a happy medium. I may drop back to 40% just to be on the safe side.
How Did I do it:
I ran the car until the red light came on and filled up with veg
drove to the petrol station 2 miles away and put derv in.
Drove back, this should have cleared the lines of old mixture.
leave for 2-4 hours then start (or try to) again.
when started added magic can of extra derv (10L) to the tank and left to run for a few mins.

Who said common rail engines dont work from veg oil! 
As soon as i can find a short wheel base series 2A landrover I shall repeat the experiment with 75% c/w pre heater then take it to 100%. Anyone know where there is one for sale?

We have one on the farm but it was nicknamed the slug due to its lack of performance however putting a discovery engine in seems to have cured the problem.

I haven't had any problems with my clio, running it on home made biodiesel 50% of the time, and usually adding 10% SVO (to both biodiesel and dino diesel).

I also did some experiments in test tubes beforehand: Once, someone told me that diesel and veg separate out, and the veg oil at the bottom then enters the fuel pump at 100% rather than at the dilution intended. Having tested that, I can vouch that the veg oil mixes/dissolves very well in/with diesel or biodiesel, even without mixing.

I have a Seat Altea 1.9 TDI - same engine as the golfs.  Bought in Spain and on the fuel cap it specifically says not to use biodiesel.  I can't seem to find any reason why this is so.  Am thinking that it could be because of the poor quality of biodiesel in spain (which produce too much emissions) rather than anything in the engine itself.  Any ideas?

Do a search on this forum for VW BIODIESEL etc. The answer isn't known, but we've discussed the points.

as long as you get good quality biodiesel (BD) then it should be fine, the motor manufacturers like to cover themselves against anything and plenty of other people are using 100% BD in their motors against the manufacturers advice saying that should a warranty claim arise it would be up to the manufacturer to prove that biodiesel caused the problem.

John,
I agree it is a slow engine unless you buy the ECU upgrade which runs just fine and more mpg.
My brother in law puts some of my veg oil in his golf TDI with no problems.
