Modern diesels?... PFM!!!
Have just passed the 300,000 mile mark on my Citroen BX19 turbo-D - 90 mph+ at part throttle (for overtaking, you understand!!)and the critical 50 - 70 overtake is a more relaxed business than on anything else I've driven. However, DON'T PUT PETROL IN THE TANK!!! I did - cost me well over a grand to fix
