hi guys been reading on another site how most members are running thier land rovers on vegatable oil has anyone any experience with running a skoda sdi on the same any info would be great thanks lads

It can be done but you just need to check what fuel pump you have.

If it's a Bosch made one then you're fine but anything else you're asking for trouble.

I used to run a Pug 306 1.9D (XUD9) on a 50/50 mix of diesel and veg oil with very good results. Even ran fine in -15c temps over in Germany one year.

cheers phil im not very mechanical minded . any idea how i tell if i have a bosch pump . i should know i worked for bosch for 11 yrs lol

Take engine cover off. Pump is in front of you with pipes from fuel filter and to injectors. Look down back of pump casing, there should be BOSCH.

I run about 50:50 in the winter and 75:25 in summer using Tesco sunflower oil at £1.00 per litre. My fuel consumption is up a bit but more than compensated by the oil price differential.

So your telling me I could run my vRS on oil???

Absolutely not!!!. SDI engines only with Fabias.

Dam! I thought I were going to save some money :/

thank you very much peter

Well said.

Not even in a million years can you use Veg oil or even pure bio diesel on a PD engine!

I raised this same question a while ago.

No hard evidence available to say you shouldn't - just hearsay. I've run several tanks of 50/50 veg/derv mix through mine, with no issue..

Yes, it might crystalize in the injectors, yes it might duff the fuel pump, but a a few tanks worth easily covers the cost of replacing those parts.

We need a volunteer to test this until destruction (or otherwise). Any takers?

It'll cost you a hell of lot more if you knacker up the injectors and fuel pump! lol..... Keep the veg oil in your frying pan not in your vRS

No hard evidence, except the dire warnings VW issued about using Bio diesel in PD engines, but none the less I'm interested to hear of your experiment.

Really?.........I suppose you could pick up a set of second hand injectors for £300....a fuel pump for maybe under £100 second hand.

But........don't forget the turbo. It's probably getting really sooted up.......once the vanes start sticking it's the beginning of the end. If it becomes unbalanced and flys apart, it is the end......£700?

I think the issue is with the pump injectors.

They can't handle the higher viscosity of the veg oil and can break.

Definitely not worth trying!

I was thinking you can put a PD pump oin a non PD with a relay and some extra cables, and replace the fuel level sender with the one with the pump, so could you add a non PD pump to a PD engine...?

The origins of the post refer to SDI which as far as I am aware is non PD, the best answers may come from :-

That thread lasted less than 2 weeks, so god knows what could have happened after he ran it a bit longer. Also he didn't that knowledgeable about his car in the first place. The idea of pumping a more viscous liquid through the PD injectors given the silly pressure involved does seem like a recipe for disaster.

Yea not to mention he thinks the vRS has a DPF

He seems to be running Biodiesel and not Straight Vegetable oil (SVO).

The situation regarding biodiesel is more complex. http://www.volkswage...l/biodiesel.pdf

VAG say Fabias built up to the middle of 2006 can be run on 100% biodiesel as long it is Rapeseed Methyl Ester bio diesel.

If that guy is making his own biodiesel as opposed to just putting veg oil in, he'll probably be ok.

Good point.

I doubt it.

Plus you are still left with the issue of the pump injectors being the weak spot with veg oil.

Although the pump then may be up to it the actual injectors that pressurise the fuel etc wouldn't be able to handle it.

Do you mean the pump in the tank. I thought the head on a PD engine is completely different to the injection pump emgines.

I need to take a close look. I have a non PD Octavia, the wife has a PD A3, ill park them side by side.

The PD has a pump in the tank, a non PD has a pump on the head run off the cam belt. You can put a PD pump in the non PD tank, it ensures good fuel flow and means you reduce the strain on the non PD pump when running WVO/SVO. I havn't considered it the other way round. I had Pd injectors firred into my old Octavia and did 80k miles on them before selling it, and have put a few hundred litres of WVO through the A3 with no issues, maybe slight hesitation when cold if it isnt diluted with Dino. I am tempted to put 150BHP inhectors in the Octavia and see what happens with WVO, probably smoke city!

In a PD engine the camshaft is used to pressurise the fuel going into the injectors IIRC hence why the lift pump in the tank is required.

Sorry I know this post is a few weeks old, but an interesting post. I'm running B100 biodiesel I buy from an outlet and made to the necessary standards (EN14214) in my unmodified Fabia 1.9SDi. I have seen a reduction in mpg marginally, but it's very small. I've been running this for almost 40k miles now.

I am interested in running on SVO. Any tips on the ratios are people running their SDi with vegetable oil and what type of oil are they using? I still really think the SDi is a great simple engine and even though it is horribly underpowered, shame it gets so much flack!, Are there any newer engines anyone has run B100 Biodiesel or SVO in from the VAG group, sounds like PD's potentially may not work with it, and newer engines have a DPF which adds to more problems.
