• ? change diesel injectors (Fiat) 4 Oct 2005 (Forum)
  I believe it may not be firing on one or more of the 5 cylinders for a brief time due to fuel starvation. The diesel filter was change only 6 weeks ago when the car was serviced and the glow plugs were changed last year. When the engine is started from cold there is some white to light grey smoke that disappears quickly.
• Audi A6 smoke 17 Oct 2004 (Forum)
  Honest John has made a comment in the past about fuel timing in these cars needing regular attention, which mine has not had. I have not gone to the bother of having the fuel timing looked at because I believe that poor fuel economy would be present if the timing wasn't correct: the mpg is as good as it has ever been - excellent.

• Spanish Speed limits 4 Mar 2011 (Forum)
  A quick note for discussion, the Spanish government have announced that from March 7th the national speed limit on motorways will be reduced from 120 kph to 110 kph, this action is to reduce fuel consumption due to the current problems in Libya (where Spain gets most of its fuel). What concerns me more is that they also intend increasing the percentage of biofuel added to the standard diesel, I wonder what effect that will have on modern engines?
• misfuelling claims another victim 16 Sep 2009 (Forum)
  From the BBC website coverage of the over-by-over coverage of the ODI series: BBC cricket correspondent Jonathan Agnew on Twitter: "Put wrong fuel in car - petrol into diesel. Broken down on M1. In tow truck heading north. No chance of getting to The Oval" That will be pricey... but shows how it can happen to anyone. We bought a fuel angel, so won't happen to us.

• Ford Focus Estate - Ford Focus Mk1 - Petrol or Diesel? 27 Oct 2012 (Forum)
  Hi all, seeking advice. I am looking to buy a 200-2001 Ford Focus Estate to replace a recently dead Renault 19 diesel. I like the fuel economy of the Focus diesels (hj's real mpg suggests 36mpg petrol vs 48mpg diesel) but I'm worried about the horror stories of older diesels failing expensively (the DMF problem).
