My husband and I are trying to decide whether to buy diesel or petrol for our new car and will probably be purchasing an ix35. My parents also run a new Ford Focus diesel. We run two older diesels at present. A friend has had two breakdowns of her ix35 diesel caused by the biodiesel at ordinary pumps. The garage and RAC have told her that it has caused a blockage near the injectors (but not dpf blockage). Is this a well known problem? Which garages do not sell biodiesel mixed in with their diesel?
