• All makes and models - Possibly the end of the fuel debate? 20 Mar 2017 (Forum)
  Asda is middle of the road diesel, but he said any modern diesel car should stay away from supermarket fuels apart from tesco and use either BP ultimate or Shell v power or equivalent as they need the extra dose. Was a very interesting conversation, I wont bore you all with the rest but perhaps one step closer in the debate.
• Mazda Mazda 6 (2002 - 2007) - 2.0 diesel -fuel warning light and remaining miles 10 Dec 2007 (Forum)
  I have had my Mazda6 2.0 diesel since late October. This week I let the fuel run lower than usual before re-filling (waiting for my fuel card but that's another story)... ... so it had got down to below a quarter of a tank with the "miles remaining" readout heading to single digits.
• Hyundai ix35 - Hyundai ix35 fuel filter issues in cold weather 24 Jan 2019 (Forum)
  Are you aware of fuel filter issues in cold weather? My car (12 reg/25,000 miles) lost power and then came to an abrupt stop when driving in cold weather conditions (2 degrees C). The dealership advised that the fuel filter had clogged due to the diesel fuel used.
• Fuel price 11 Nov 2021 (Forum)
  Saw diesel at £1.68 a litre at Fleet services yesterday....ouch. Remember queuing up to buy petrol when it went up to 50p a gallon. 
• Emptying fuel tank (306) 4 May 2006 (Forum)
  Is it possible to do this? Nope, no misfuelling ;o) I'm selling the thing, and currently have £50 worth of diesel in the tank!
• Aircon, Diesel or Petrol? 8 Jun 2002 (Forum)
  When using aircon, will more fuel be used on a similarly powered petrol or diesel? For example; the Peugeot-Citroen 1.8 117 bhp 118 lb/ft petrol and the 2.0 HDI 110 bhp 184 lb/ft diesel?
• Does fuel economy improve in winter ? 18 Nov 2009 (Forum)
  Just wondering if fuel economy improves in colder weather or gets worse in winter if the same journeys are made. For me I noticed with petrol engine cars the fuel economy goes down in colder weather. Does this also apply with diesel engine cars or does this improve (air density etc) ?
• Fuel from water 23 Jul 2008 (Forum)
  Just seen an advert in my local rag saying the following: FUEL FROM WATER Hydrogen diesel fuel enhancement guaranteed 10-15% increased MPG and lower emissions £85 I already know that if things sound too good to be true but does anybody know any more on this wether it works or not?
• American Diesel 22 Jun 2006 (Forum)
  Is the quality of diesel in the USA still terrible? Or is the 'diesel boom' leading to better quality? I ask because VW diesels are the most popular there for cars (I think) so if they can run to hundreds of thousands of miles on what they sell there, our highly refined diesel should mean a very low stressed fuel system.
• Passat b7 2.0tdi - Fuel filter replacement 7 Jul 2019 (Forum)
  Hi, Just did a fuel filter replacement a 2.0tdi. After searching some posts on the matter, i've heard that incorect air bleed of the fuel line could damage/ crack the hpfp. Most people say to unscrew the 5 bolts, remove old filter, clean housing and ad new filter after the housing is filled with clean diesel and avoid puting diesel through the center hole of the filter.
• Peugeot 106 (1991 - 2002) - 1995 1.5 Diesel engine problems - tud5 14 Jan 2008 (Forum)
  I replaced the stop solonoid about 50 miles ago, but I'm not sure if a fault with that could cause these symptoms. More likely, I had not long filled up with a full tank of diesel (I definitely put the right fuel in!) before the problem started. Would contanimated fuel cause these problems? How would I check it? If so, can I get away with just draining the tank or would I have to empty all the lines too?

• Which diesel fuel? 4 Jul 2004 (Forum)
  I have followed the threads about petrol quality and it seems a safe bet to use Texaco, Shell or Esso every now and again. It's only a couple £ a year...
• Mercedes C220 Diesel Pump 21 Apr 2003 (Forum)
  Another thing is the engine runs on for 3-4 seconds after turning the ignition off. Took the car to local garage that specialises in MB and he put his test box on, the message : " FUEL INJECTION SHUT OFF VALVE" came up. The question is should I get the Fuel Injection Valve replaced or should I get a new diesel pump?
• Mercedes ML250 - Help....Fuel System Needs Replacing? 14 Nov 2014 (Forum)
  The car has been in to the main dealer 4 times, they have tried various things but failed to find the problem. They have just rang to say there are iron-filings in the fuel, this is caused by the some part of the fuel system (pump?) breaking up and must have been due to a mis-fuel (i.e. I’ve put petrol in a diesel engine) and a lack of lubrication. They say this is the cause of the stalling and the Mercedes warranty is obviously therefore invalid.
