Is it only Common Rail Diesels to be worried about?

[RIngrey]

Is it only common rail diesels that should be avoided if using Biodiesel? I'm about to get a PUG 307 and I doubt very much if I can use Biodiesel in that. A friend of mine was using Biodiesel in his X-Type Jag and suffered injector issues - hence he no longer uses Biodiesel.

Can someone explain why common rail diesels differ from other forms of injection systems and why that makes them unsuitable for Biodiesel use?

Many thanks

I think you will get a far more comprehensive response from the vegoil forum.

Very interested to get more info on the X-type Jag he was using, as that's what I drive

I'm actually still running on dino diesel, but was considering trying bio in it. I've been having a lot of issues finding out if it's compatible or not, guessing my best and only guaranteed option is to ask Jaguar themselves and get a definitive answer of what the engine system actually is.

Engine Details:

Model 2005 X-type Estate S D 2.0l D. According to my log book. Yeah not helpful at all!

From Wikipedia it seems to be suggested that the actual engine is:
TDCi 16v - 2.0 L Ford Duratorq ZSD Diesel I4 turbo intercooled 16-valve DI

Supposedly the exact engine used in the 2.0l X-types is Duratorq ZSD-420 2.0L (1998 cc) direct injection turbodiesel. 2.0d, 130 PS (128 hp/95 kW) and 244 lb·ft (330N·m).

It seems to point towards the engine being Turbo Diesel Commonrail injection, but doesn't actually say TDCi, I'm working on this assumption as it has the 130 PS, which came with the changeover after 2002 from TDDi to TDCi.

For anyone that cares to take a read and knows about the engines etc.

Do you know if it is equipped with a DPF?  That usually makes it bit of a no-no running on bio.

9500 miles from new with a DPF,only diesel its seen was the half tankfull it came with,no problems so far,fingers crossed
First service due in March so we will stick some in then

Crikey, you're brave Keith.  I take it you keep a close eye on the oil level, just in case?

*Whistles* I have no idea at all. Thinking it'll be best to ask my mechanic for details, but this isn't due until the summer months when I come to have the service and MOT done.

I might get around to it sooner, if I have some free time and remember to ring Jaguar, but with buying a new house on top of everything else at the moment, that might have to wait.

Sounds like you're doing a lot at once.

There was one 12 month period where I learnt to drive, got married, got my first job, first car, first house and first child.

By comparison the rest of my life has seemed quite relaxing

The engine in the Jag is the same as in a ford mondao,
I beleave it's actually a PSA engine with ford injection system (now where near as good as the PSA system).
The jag and ford both suffer with the injection system even with pump diesel, so the chances are it wasn't bio that killed the injector.
Do not ask Jag if you can run biodiesel, they will tell you not to use anything but pump diesel.

There are a few people on the VOD running DPF fitted cars without problems.

[Ross.Dunmall]

Well I spoke to my mechaninc who confirmed that the engine is a Commonrail Diesel fitted with a DPF Filter.

Yes I know that the engines are pretty much the same as the Ford Mondeo. Previous Car was a ford mondeo and I refer to my Jag as a mondeo with a face-lift, since chasis is identical and it's only a few internals that have been changed specifically for Jaguar.

I know the engines are tuned differently (well they were to start, I think they adopted the same engine later for higher end versions of the Mondeos).

My mechanic said he didn't know in all honesty if it'd be compatible, and said you do need to be a little careful. The search goes on.

Apparently one of the issues which perhaps is what your friend suffered is that Pump Diesel can noften only be filtered down to 40 microns, just enough for the pumps and filters to deal with, so that could well have left residue build up in the tank which then got pulled through with the bio blocking the filters etc.
