Has anyone tried mixing cooking oil in their diesel. If so, did it work OK and didi it save any money?

Son uses 50/50 in his Passat - no problems.

Depends on the engine, it will damage some.

Used to work for a twat who filled his new Merc vito van with Aldi's special, and blew up the engine in his new van.
Ok on older engines maybe, but I would reckon it would glaze up the bores and gum up the valve stems and rings through time, probably costing more in the long run.

It's normally the injection pump that fails first - especially on the new "common rail" diesels. I'd not think twice about it in an old boat engine but can't be bothered for the amount of fuel it uses in a year. I definitely wouldn't in a common rail diesel though. Some major manufacturers are even a bit "proud" about whose "proper biodiesel" you can use! There's no EC standard yet, as far as I'm aware, for pure biodiesel so even the likes of Peugeot, who say their engines can run on up to 30% biodiesel have to "vet" the companies making it before they'll honour the warranty.

I have used recycled cooking oil in a Landrover Discovery and in my current Mitsubishi Delica without problems. I installed one of those inline paper fuel filters before any of the other filters and changed it regularly. Used 50/50 mixture with no problems other than slightly harder to start in the winter. The viscosity of the oil is obviously higher and I believe this can cause any dirt in the tanks to be more easily carried to the engine - hence the extra filter and the need for clean tanks in the first place.
Of course if anything goes wrong in a car a lee shore is unlikely to be a problem and all you need to do is call the RAC/AA/etc.

Avoid veg oil with lucas/cav/roto injector pumps as they are prone to overheating and welding the rotor solid, also rubber o-rings swell with veg oil, I have heard of internal mods to sort the lubrication problems and using viton o-rings but have never tried it.
I think bosch injector pumps are fine with veg oil.

Biggest problem is that unused cookin oil is almost the same price as diesel, it didn't take long for the supermarkets to catch on.

Not really appropriate but following is a response from Fiat/Alfa in respect of running their cars on bio-diesel...
Thank you for contacting the Alfa Romeo Customer Experience Centre. Further to your e-mail on 11th October 2007. I am pleased to confirm Biodiesel can currently be used on our entire Diesel vehicles but only in a minimal percentage, namely not more than 5% mixed with regular diesel fuel. The use of ‘Biodiesel’ in the quantities given above is permissible without the need to make adjustments to the fuel system with the ‘Biodiesel’ and European EN 590 specifications being conformed to. The use of ‘Biodiesel’ in quantities which exceed the recommended amount described above can cause problems with fuel system components. Improper usage invalidates the warranty. I hope this information helps. Best regards,
Most of the car manufacturers will suggest a warranty problem if bio used and newer Mercs and Beemers are not even able to run on it. The Goverment 2,500 litre rule makes it economic to run a diesel car this wayits just a question of can you be bothered to produce.

Yes - I've been running SWMBOs Renault Laguna on 30% Lidl veg oil with no problem at all (few thousand miles). We've stopped now because the price of veg oil has rocketed to match fuel prices.
Check the web - a number of sites will tell you whether your car is suitable to run on veg oil without mods such as fuel heaters.
Generally, older, non common rail engines are ok. Make / type of fuel pump is a factor. In Renaults, Bosch fuel pumps are fine, others not so.

There are various references to B5 diesel fuel and through Hubby who is involved in Oil trading, it is that B5 is standard diesel fuel with up to 5% biofuel added. According to him and the references, up to 5% is not required to be declared and is commonly supplied in EU filling stations incl. UK.
Hubby reckons that Motor manufacturers are "covering posteriors" and ignoring the fact that B5 is already generally out there.

Well that told me then!! /forums/images/graemlins/blush.gif
I supposed I should have chosen my words more carefully! I think what I should have said was that there was no standard that all car manufacturers had agreed to adopt, in the EC at present!
I work type-approving cars and although emissions isn't really my thing, I have a vague feeling that all manufacturers are obliged to declare that their vehicles can run on at least 5% biodiesel mixed with "ordinary" diesel - so they can't squirm out of that one, hence the reply from Fiat / Alfa above. Peugeot are, I'm pretty certain allowing the use of up to 30% biodiesel but only if it meets with their own in-house standards.

I'll second that.
When it was first mooted that cooking oil could be used in diesel engines, Herr Diesel did design his engines to run on vegetable oil, you could pop down to the supermarket and buy a litre for 16p .
The cost per litre now is very similar to that of petrol!
