  Used cars with low fuel consumption 6 May 2011 (Ask HJ)

• Vauxhall Astra F (1991 - 1998) - 94 1.4 non starter 10 Aug 2009 (Forum)
  Thought that I just might have a slight inlet manifold leak and retorqued the nuts. The awkward lower ones were a little loose. Tried starting and no joy. Checked fuel and there was no pressure at the Schraeder valve. Tried again. Pump worked for a second. Enough for the engine to catch but only splutter and then it cut. From then on no fuel pump at all. Checked the fuel pump relay off car.

• Ford Mondeo III (2000 - 2007) - 2003 2.0 Flashing glowplug light & engine turning 8 Feb 2009 (Forum)
  Turbo seal leak needs repaired 3. Failed injector or loosing it's calibration and needs re-coded 4. Pressure sensor on fuel pump 5. Fuel filter and fuel gauge sender unit 6. EGR valve needs replacing 7. Fuel pipes being a bit knackered having holes in it and drew air into it 8. Fuel pump disintegrating or being blocked which in turn could be affecting the injectors Apparently there have been a number of Ford service bulletins about TDCI Mondeos cutting out.
• Poor fuel quality Kent SE England? Vol 1 1 Mar 2007 (Forum)
  I can only assume that something within the fuel is coating the sensor and stopping it performing as intended. I do know that fuel samples are being tested, and will post results when known......but until then....be careful, it may cost you £250.
• " fuel Saver Tyres" (Proof?) 17 Nov 2006 (Forum)
  I`m a little cynical about claims in general..( maybe by being exposed to too many engine oil/additives/petrol, magic particle/bonding to metal and mileage claims in early life :) Anyway, It turns out the van has *Firestone Fuel Savers* fitted. I wondered if most new vehicles have similar tyres fitted these days and if so where is the hard, scientifically measurable evidence for fuel saving? IMHO it must be easier than trying to measure something such as fuel consumption under road conditions.
• Mk1 Leon temp gauge & fuel gauge 31 Mar 2006 (Forum)
  Both the fuel gauge and temperature gauge have been intermittently faulty for a while now - I had the dealer run a diagnostic check and the fuel gauge sender needs to be replaced (fault code 00771 030 - open circuit or short to positive), as does the coolant temperature sender (code 01039 030 - open circuit or short to positive).

  How do you compare the fuel economies and efficiencies of electric versus petrol/diesel cars? 26 Apr 2021 (Ask HJ)
  With the coming of electric vehicles, wouldn’t it be better to start referring to all vehicles economy as MP£ or Miles per Euro as standard rather than...
• Any - Real Fuel Saving at Low Cost 4 Sep 2020 (Forum)
  For example, improving fuel economy from 51 mpg to 59 mpg in June/July 2019 on a 94 mile round trip, with the car driven gently (no aggressive acceleration or braking) but cruising at around 65 mph on dual carriageways. That is a 16% improvement in fuel economy.

• Ford Focus (1998 - 2004) - 2001 1.8 Cutting out/hesistation maybe fuel pump? 11 Oct 2008 (Forum)

• Volkswagen Golf MK6 2011 tdi 1.6 - My Car vibrates on Idle after fuel injector change 24 Feb 2023 (Forum)
  Hi, Just had my fuel injector changed, car is on 85k miles. I've noticed the car vibrates when idle now at traffic, or when im at traffic and foot is on brake. I've done about 20 miles since had this from the mechanics, should I drive it a lot more to let the ECU learn or something and will this ease the vibrating at idle?

• Renault Clio III 1.5 DCi - Clio 3 1.5dci fuel safety cut off 30 Nov 2019 (Forum)
  All i can think is that kicked the front bumper pretty hard in frustration, could this have tripped some kind of safety fuel cut? Any help greatly appreciated TIA
• Any - Tyres 5 Apr 2017 (Forum)
  The cheapest tyre was £60.83 and was branded BlackCircles with 4.9/5 rating and C ratings for fuel economy and wet grip. Next cheapest was also BlackCircles for £64 odd but worse ratings E for fuel and C for wet grip. Looking down the options most of the mid-range options are worse rated than C/C and even the premium ones are only B for wet grip and usually the same or worse for fuel economy.

   I've changed the ECU temperature sender, the coil, the ignition amplfier and the distributer (with the hall effect dectector within).  There seems to be spark at the plugs..  So are there any fuel system or any other components that could do this?
