TD5 on biodiesel

[Newromancer]

Recently I discovered a filling station selling bio-diesel. 100% rape-oil to be specific.

I would like to give it a try, but the user manual (Defender TD5) claims that the engine does not run on 'bio diesel' and warns you from trying it.

I find that a bit hard to believe, has anybody else tried to run a TD5 engine with bio diesel?
If it really doesn’t run on bio diesel, what kind of modification would the engine need?

Thanks,
Christian

I've never heard of a Td5 running on bio it might be possible but bio does f**kup the pump IIRC which would cost a packet to replace.

Thank you greenlandy.

I was googling for bio-diesel in common rail engines, and annoyingly I found both answers. Some claim no problem and others warn no-way.

The best discussion I found was this here.

If I understand the problem correctly, particles within the fuel could jam the injectors (pump) could get jammed. No need to say that this would be quite expensive to fix. A good enough reason to run a TD5 not on veggie (cooking) oil from the supermarket.

However, bio-diesel from the filling station should be a different matter. Especially if it is DIN certified.

Personally I had good results from mixtures with up to 70%. In Austria every Diesel must have 20% bio ration anyway. Running the car on bio-diesel all year round is not an option (not even in Ireland). It would be more like an occasional thing.

So what I am really hopping to get are people telling me experience with 100% bio-fuel in a TD5 engine. Or somebody telling me what needs to modified, how much it would cost, and why?

It is kind of strange that a Defender should be fitted with such a fragile engine. In India for example most of the fuel is from very bad quality. And that would be perfect Landy terrain.

There's a diesel pump specialist near me his name is Brian Green he is the man to ask IMHO tel:[phone]

A friend runs his disco (no idea which engine) on oil from the local chip shops. He collects it from them (and is paid to take it away) and stores it for a couple of months so it settles out. Has been doing this for years.
