Just in case anyone is thinking of making their own BioDiesel you would be well advised to have a look at this. If you have a diesel engined car or van, check the hadbook, it should tell you in there if it is safe to use Biofuels


Biodiesel is produced from oilseed rape, sunflower oil, used frying oils and palm oil. Unless a vehicle has been specifically designed to use it, this can damage cars.

In the UK all diesel contains up to 7% biodiesel. In France the proportion is similar, However, a B30 diesel blend (containing 30% biodiesel) is also available in France (and other parts of Europe), and it is this that has caught out some British caravanners. B30 is only suitable for vehicles specifically designed to use it.
Journalist and experienced continental caravanner Mike Cazalet believes the problem is that various seals in the fuel system are not suitable for bio fuel. He advised: “The seals may not fail immediately, which is why people who have filled up with the wrong fuel often think they’ve got away with it, but the seals probably will, expensively, fail.”

Motor manufacturer Nissan, along with most other manufacturers, advises customers to use only conventional diesel fuel, and Volkswagen says the use of B30 may invalidate the engine and exhaust system warranty.

A few filling stations in the UK also sell the B30 blend – Morrisons supermarkets has stocked this at its forecourts.

To avoid problems, we advise:


Stick to conventional diesel fuel
Avoid B30 – look out for the B30 label and possibly an orange pump
Use B30 only if you have established with your car’s manufacturer that your vehicle is able to run on this mix

Funnily enough, Renault, Citroen and Peugeot should be alright on it but most of the others are not ie Fiat, all the German lumps and most of the Far East beasts.
It can be a very expensive repair.

Ya know it is funny that the original Diesel engine was designed to run on vegetable oil? Shame they got hooked on Dino fuel
