• Using bio diesel in Honda civic 2.2 14 Jun 2006 (Forum)
  I can't find any information on the internet about using bio diesel in the new Honda engines. Although I would normally try anything once it's a big risk deliberately putting the wrong fuel in a brand new car. Does anyone know of any reason why it should be any less suitable for bio fuel? Any thoughts or comments welcomed.

• coasting in neutral 4 Jul 2005 (Forum)
  My route to work is pretty hilly and on some of the gentler downhill slops I tend to drop the car into neutral to let it coast along around the speed limit, with the aim of saving a little fuel. In some of these situations if I was to put it in gear with foot off throtle the engine braking effect would be too great thus requiring use of the throttle and a waste of fuel. Is there anyting wrong with coasting along in neutral, both in mechanical and bad driving practice terms?
• peugeot 106 diesel leak 17 Jan 2005 (Forum)
  Starting has been getting gradually worse up to a point where it requires priming every time to start now. Further investigation has led me to a diesel leak above the fuel filter housing. When priming diesel leaks quite fast out of the outlet above the fuel filter. When the engine is running air bubbles can be seen in the clear pipe running from the filter to the pump.
• Speedo/Tacho. Stopped Working - BMW520i 8 Jan 2005 (Forum)
  Could anyone kindly shed any light on this - I'm hoping it could be a fuse although I guess the speedo, tacho and fuel gauge all registering zero on the move may suggest a faulty cable?? Greatly appreciate opinions
• Audi A3 Fuel Economy 29 Mar 2004 (Forum)
  I've done about 1400 miles in the A3 now, and all round its a very nice car, but the economy seems a little on the low side still, the only way to break...
• Erratic idling on Omega? 19 Apr 2003 (Forum)
  On travelling at around 30/40 m.p.h it tends to hold back then pick up then hold back and so on. The fuel pressure valve fitted to the end of the fuel rail "hisses" as if its leaking air? The car also "pinks" on acceleration too. so does anyone have any ideas before i burst into tears?
• Shell vs supermarket 27 Nov 2002 (Forum)
  Recently I have been attempting to use Shell diesel when possible, but the last 4 times I have filled my Polo have been twice from the Shell station and twice at Tesco. Both times at Tesco I have noticed the fuel markedly more frothy and difficult to get brimmed full (to measure fuel consumption - anally retentive I know...) I was wondering what information this gives on the content of surfactants to help keep the engine clean??
• Please help me with 4x4 query? 15 Nov 2002 (Forum)
  The missus wants to bet rid of her current car (Mitsubishi GTO 3000 twin turbo) as we have moved to the country and the fuel consumption is a bit heavy now she is earning less. She wants to buy a 4x4 but the fuel/mpg figures are quite shocking talking to local people with Range/Land Rovers etc. Could anyone tell me what 4x4's give the best MPG?

  Fuel tax is one thing but they are having a laugh putting vat on the tax already imposed.....what a cheek!

  Does anyone have any experience of using this fuel-additive product, which claims to reduce 'bad' emissions? Roger

  My Toyota RAV4 2.2 diesel is disappointing in its fuel economy and only averages at 27mpg. I would like to have something with similar versatility, comfort...
• Citroen Relay - Citroen Relay - Van Smoking Heavily! Please help 14 Mar 2016 (Forum)
    At first I thought fuel injector 3 was the problem as when I pulled the power it continues to idle a bit rough but nothing too serious this is why I did the clean though it might be a bit of debris needing cleaning, My first thought was no 3 injector had failed so to test I swapped it with number 2 ran at 2000 rpm for 10 minutes to clear the excess fuel then pulled power on injector 2 to confirm bad injector but it stalled and new injector 3 still ran  any ideas I'm stumped  thanks in advance for any help
• Peugeot 406 2.0. Hdi fuel consumption 29 Dec 2015 (Forum)
  I bought the new car because of its condition and service history but I am very dissapointed with the fuel consumption. Any suggestions? Thanks.
• Ford Mondeo 2.0 Diesel 2005 55000 miles - Glow Plug Light Flashing/Engine Cutting out 27 Oct 2015 (Forum)
  It may also go into limp home mode and the engine management light will come on. The issue will be in most cases the Diesel Injector Fuel Pump - cost to replace - about £1100! Don't listen to anyone about water in the fuel, camshaft sensors, crankshaft sensors, even injectors. These are all red herrings. There is a known problem with the internal workings of the fuel pump that fail and send swarf through the system.
• Volkswagen Bora - Brain teaser.. 52 plate Bora 1.9 TDI wont start 18 May 2014 (Forum)
  When the car is cranked over, all readings on my mates snap on diagnostic seem correct. We used a NOID to check the trigger signal to the injectors and all appear ok. When the fuel feed or return to the tandem pump is removed fuel sprays out therefore lift pump is working and filter not blocked. Fuel is clean diesel too. No engine oil in it or veg oil present. With the dreaded easi start hastily sprayed in to the inlet the engine will run but it is running on the easi start.
• Ford Focus II (2004 - 2007) - 1.6 (115) poor fuel economy..help! 19 Aug 2013 (Forum)
  Otherwise, nice car despite the annoying habit of not starting if I leave it parked on a (upward) slope if the fuel warning light is on! As always thanks in advance Steve
• VW Passat - Fuel injectors failure on VW Passat 55 plate 28 Jul 2012 (Forum)
  I came accross your site by luck, and did find out that we were not the only one troubled by fuel injector failure. When injector 1 failed, the car had only 55k miles and was 6 years old.....and did cost £880 to fix at a local garage. It was repaired but they said that the other 3 are likely to fail soon.
• Budget 2012 21 Mar 2012 (Forum)
  The 'gain' for low earners will be wiped out by fuel increases and despite the Commons voting to bring fuel prices down last year it seems the Chancellor will actively disregard that and increase it anyway. It remains to be seen what other motoring related news will come out of this budget, i've heard no word on any VED increases or anything.
