• Fair Fuel UK/Panorama etc 27 Oct 2011 (Forum)
  Those in the UK can watch it here http://www.bbc.co.uk/iplayer/episode/b016bycy/Panorama_The_Great_Fuel_Robbery/ Its obvious to me that the easiest way to destroy these criminals income and operations is to make fuel reasonably priced in the first place, then you wipe out their marketplace. We're now at a point where its not just 'fuel thieves' and low level criminals who are happy to turn a blind eye to where its come from, its now the normal man/woman in the street looking to get to work and back.

  Does my Peugeot 407 really need diesel fuel additive? 9 Sep 2010 (Ask HJ)
  In my 2006 Peugeot 407 SW SE, diesel fuel additive should be checked at 70,000 miles and running out can lead to massive bills. Mine required three litres...
• n/a - E85 ethanol versus neat petrol test. 21 Sep 2021 (Forum)
  E85 is no longer widely available in the UK. As this test was carried out in the USA in 2009 the fuel price comparison is almost certainly not valid, but the consumption and environmental advantage conclusions stand. Two 667 mile round trips San Diego >Las Vegas and return. The same flex-fuel vehicle used for both tests.
• 2007 Ford Focus 1.8 TDCI - High Fuel Pressure issue 8 Jun 2021 (Forum)
  Hi, My focus has developed a problem where upon starting the car runs for a few seconds then cuts out stating 'engine system fault' and will not restart. RAC plugged in and seems the fuel pressure was too high with error code referencing the fuel pressure sensor. Having reset / cleared the errors the car re-started and after a short time pressure went to normal. RAC suggested a bit of dirt as seemed to sort its self.
• Ford Fiesta Mk4 facelift 1.25LX year 2000 - Intermittent electrical wire problem 20 Feb 2019 (Forum)
  Good Morning, I am hoping someone can steer me in the right direction, my wife has a very clean year 2000 Ford Fiesta, recently after a no sytart scenario a mechanic diagnosed a faulty fuel pump. A new pump was fitted via a hole that was cut under the n/side rear side pan. The  car now starts and runs fine but now the fuel gauge indicated zero ( it has half a tank ) I know the new pump had a combined fuel float device.
• any - how long to get the best from your vehicle 3 Aug 2018 (Forum)
  Progress that is, improving your driving for smoother, not slower progress, leading to quite large improvements in fuel usage. I reckon it takes me about 4/5 months before i can get the best from a new to me vehicle, though i don't think you ever stop learning. Was issued a new lorry at work in Feb, and we have fuel consumption displayed automatically on the depot fuel pump every time we refill.
• Peugeot 307 2l hdi 2004 - Fuel gauge not registering refils 3 Mar 2017 (Forum)
  After another 60 mile the fuel level was reading lower as you expect, but the next refill again didn't increase on the gauge. What is going on?  The gauge correctly shows fuel use but not the refilling. Has anyone any ideas please.
• Jaguar XFR 2011 - Jag XFR Needs New Fuel Injector(s) Post Re-Fuel 11 Oct 2016 (Forum)
  Is there anything we can do to claw back some of the repair bill from the main dealer. In addition, could this have been caused by petrol contamination at the fuel station and if so how do we go about investigating this? Should this really have happened at such low mileage? Very grateful for any advice please. Thank you.
• BMW 116d EfficiencyDynamics - BMW 116d EfficiencyDynamics fuel consumption? 4 Oct 2016 (Forum)
  I bought my very low mileage 13 plate BMW 116d EfficiencyDynamics 6 weeks ago and generally love it, however I am more than a little bit peeeeved about the heavy fuel consumption! For many a long year I have owned diesel engined cars and I have always managed to achieve quite exceptional brim to brim fuel consumption figures, for instance my last car was a Peugeot 307SW 1.6 HDi and I was regularly getting a corrected 60+ mpg.

  Why do automatics use more fuel? 26 Nov 2014 (Ask HJ)
  Why do all the new Korean cars (Kia, Hyundai) have such appalling CO2 and fuel consumption figures when an automatic 'box is fitted? I wrongly thought...
• Honda Jazz - 1.2 Honda Jazz motorway fuel efficiency 1 Oct 2013 (Forum)
   The acceleration pass 50m/h isn't vey good and I have to keep the engine at almost 3.5k rpm to keep the car at 70m/h.  Is this bad for the car and bad for the fuel economy as well?  I have taken the average fuel consumption over three days and I have got approx 40 miles per gallon.  This is acceptable for a 1.2?  For my journey, it is mainly 90% motorway, and sometimes I have to due with traffic jams with the remaining 10% journey.
• Peugeot 306 (1993 - 2001) - 2.0 HDi fuel problem? 25 May 2012 (Forum)
  Peugeot 306 2.0 Diesel HDi. History: Car broke down, diagnosis by AA was fuel pump. Pump was seized (This is the fuel pump that sits in the tank) I replaced the pump with another VDO part. Since then intermittently the engine will only rev up to a maximum of 2,300 rpm. Its like it is limited at 2,300.
• Renault Grand Modus - Warranty Repairs 2 May 2011 (Forum)
  I own a Grand Modus which a few weeks from expiry of the warranty. On several occasions it has had a intermittent fault in that it after fuel has been put in the fuel gauge does not change. The "gauge" consists of coloured blocks which "light up" on a black ground to show how much fuel is in the tank. Last week it showed one empty block so I filled the tan until the pump cut out.
• Does cruise control use more fuel? 26 Jun 2010 (Forum)
  Does cruise control use more fuel?   This applies to modern cars.   This is my style of driving a car without cruise control. I accelerate gently, not sluggish or harshly.
• ford mondeo - Ford mondeo mk3 petrol fuel pump problem 31 May 2010 (Forum)
  In my opinion diagnostics are rubbish they were saying it was the egr valve on one and air sensor on other then another said it was the cat no one said the fuel pump. so can someone tell me is it common ? Thanks   Jason
• Citroen ZX (1992 - 1998) - 1993 1.9 starting problem - hot and cold 17 Jan 2010 (Forum)
  The car's done 180k but over the last 40k is been progressively difficult to start needing several turns before firing, otherwise runs fine. Of late I have to pump the fuel primer bulb to get it to go. OK to start inside of 1hr after initial start otherwise back to the bulb. I think its either getting air into the fuel or the pressure in the fuel system is able to fall when not running thus being a dog to start as the pump is initially starved.
• Peugeot 205 (1983 - 1997) - 91 1.6 Fuse Box/Fuel Pump Intermittent power failu 8 Dec 2009 (Forum)
  I know 100% that it is a problem with the cables(loom) that connect to the fuse box,, the problems is every now and again the fuel pump will cut out, i have had the car specialists in to look at it, since being told to replace the fuse box, fuel pump relay and ecu, the problem still persists, when the engine cuts out i proceed to 'wiggle' the fuse box itself whilst coasting down the road, and the majority of the time, this caues the fuel pump to start working, this fault must be caused by a loose or faulty connector on the loom, ofcourse i have no idea which connecter that connects with the fuse box does what!
• Peugeot 307 SW (2002 - 2008) - 2005 2.0 How do I prime the fuel filter 27 Feb 2009 (Forum)
  How should I drain the water and how should I prime the system ? Also, Haynes mentions that when you replace the fuel filter, the housing may break and has to be replaced ... is this true? Thanks in advance for any comments.
