Pretty sure you can't use it with modern diesel engines - how old is your mates Passat?
My BMW says "No Biodiesel" on the fuel filler and the engine warranty is void if it is used. Modern DI engines use the diesel as a lubricant in the injector system.

Fiats only allow 5% biodiesel in the X250, which is standard pump diesel on the Continent.

fuel companies spend a fortune in giving us a quality product that should not be messed with.
Plenty of forums out there with sad tales of damage done to engines.

Would your mate cook his chips in diesel if it were cheaper than vegetable/cooking oil.

My friend (also a motorcaravanner) works in the local supermarket and says a lot of people are buying cooking oil for their vehicles. Having said that, neither of us wish to risk it in ours!!

I guess that you're in the business........ you're spot on anyway. Modern common rail engines are highly developed to run on specific grades (EN 590 in Europe) - the engine manufacturers spend a fortune on testing of engines and testing of the fuel that runs in those engines, so why risk messing up your engine for the sake of what is (big picture) a relatively small saving?

High concentrations of biodiesel will attack the seals in the engine, goodness only knows what chip fat will do. I have some wonderful samples of the crud that falls out of this oil when people half heartedly try to make F A M E out of it.

When it is cold, it goes into a slushy sludge - biodiesel does not have good cold properties.

Finally every 5 litres of corn/whatever oil you buy for fuel has deprived someone of a massive amount of corn/whatever for food either here or in the third world, which has caused food shortages and driven up prices causing starvation and also is a contributory factor to the current poor economic situation. A slight exaggeration, I know, but it helps make the point.

Off my soap box and grabbing my hard hat

Spot on Dux. Bio-fuels make sense only if they are grown on set-aside land which is currently unproductive (ie that in the EU) ie where the sunlight energy will be harvested which where at present it isn't.
Creating a MARKET for bio-fuel worldwide only produces the above cited problems - because capitalists only care about revenue and not about people - FACT!
And governments care only about their image and not really solving real problems - VERY OFTEN & DEPRESSINGLY TRUE!

Hello,

I have a Friend in france who runs her car on SVA. However it is an old Peugeot. If I had my old Citroen C15 from years gone by I would give it a go. However, with Modern Diesel Engines CDi, TDi, Pumpe Düse etc, not a chance. The fuel has to be injected often through piezo injectors at 2050 bar (a shade under 30,000 psi). Don't want to bugger them up with spry crisp and dry!.

Trev.
