  I have also been replacing the fuel filter regulary (the last being 2 weeks ago) This is due to running it on some 'cheap' diesel due to financial issues. Today it was having problems starting & tonight I had to start it with 'Easy Start' On the way home from work, the power dis-appeared & then a mass of black smoke was billowed from the exhaust.
• Mini Diesel - Putting the wrong fuel in my car! 25 Jan 2013 (Forum)
    So not giving up I used it without the cap.  However that wasn't successful either. The pump kept cutting out and what little fuel  I did get into the tank just came back out and covered my skirt and shoes in pungent smelling diesel.  Not great when I am off to a business meeting!.... I now have a product called Solo Diesel and it is brilliant.

• My question to an MP regarding Bio-diesel - Reply! 4 Feb 2011 (Forum)
  Biodiesel has a lower flash point than conventional diesel fuel, and when extra fuel is injected to produce the temperatures required to regenerate the DPF the ‘bio’ element of the fuel is left behind unburnt in the engine, gradually increasing the engine oil level to the point where the car ‘self-fuels’, i.e. burns its own oil, rather than fuel from the tank.
