 Anything known about using bio-diesel in XD2 and XD3 series engines? They clearly were designed before this became available in UK, is there a view about this being acceptable or inadvisable? I'm not considering the 5/10% blend sold in some places but the full monty.

I thought most 5% low sulpher City diesel was veg based? I know the 30% blends of veg to minerel can only be used in some HDi, without voiding warranty but this needs to be checked to specific applications. It must meet EN590. On older engines the general rule is Bosch pumps dont complain, but Lucas ones the rubber seals rot on strong veg based fuel. 5% or EN590 should be fine though. (basically think twice before bunging in Sainsburys Veg oil). have a look at www.biodieselfillingstations.co.uk/approvals.htm |

Biodiesel is a complex topic.
In theory all diesel engines should work on biodiesel, as the engine was originally designed to be an alternative to mineral fuel. Older peugeot engines have actually proved to be one of the better engines to run on bio-diesel.
It is advisable to gradually change over onto biodiesel over a couple of months, and then change the fuel filter, as the biodiesel acts as a natural cleaner and removes all the crud form the tank/lines! You would be surprised at the ammount that i dug out even after just using 5% blend.
You may notice that the car is slightly harder to start in cold weather, due to the properties of the biodiesel, but proper manufacturers should adjust their mixtures to cope with this. it is also inadvisable to run a car off staright vegetable oil (SVO) as this can gum up the injectors, and also is illegal.
The rubber components of the fuel system can be vulnerable, they tend to rot when made from the older natural rubber rather than the more recent synthetic stuff.
if running a car within warranty period i wouldnt advise using above 5% blends as this invalidates a lot of warranties.
When running on the biodiesel you should notice that the performance and fuel efficiency increase because the fuel acts as a natural lubricant and also burns more efficiently than mineral diesel
I hope that this helps. the biodiesel filling stations website shown by matt is quite helpful to start with, although there are many others out there with lots of information on them

 Thanks to both! There is a non-branded place selling bio-diesel near me for 75p/litre. It is I think a farmer who has 'diversified', and from the price I imagine he is selling 100% bio since it is supposed to attract a fuel duty reduction of 25p/litre or therabouts. I'll check if it meet the EN standard, it's on a main route so I expect Trading Standards would have 'done him' if it wasn't EN compliant. It's this stuff which I was contemplating feeding to my 20-year old XD2S engine. The info. about changing over gradually and then changing the fuel filter is really helpful.
