• Fuel economiser. 12 Sep 2007 (Forum)
  I have just received an advert. through the door for a "FUEL ECONOMISER & ENGINE PERFORMANCE ENHANCER", which will give me up to 25% more MPG, and more power. I don't think so. "Up to" clearly includes the figure 0 - possibly, the thought strikes me, this could be negative!

• VAT receipts when buying fuel 17 Feb 2007 (Forum)
  Is there a (legal?) reason why a 'VAT receipt' must be specifically asked for when paying for fuel? I need to keep them for my book-keeping, and have occasionally forgotten one. Why can't the VAT element be shown on the receipt normally issued?
• Zafira fuel gauge 6 May 2005 (Forum)
  Depending on which way I'm parking (and it's not a particularly steep camber ) my fuel gauge seems to vary about by a quarter of a tank. It also takes about five minutes to level out on the flat. Is this typical of Vauxhalls or is there some kind of damper mechanism that's getting stuck?

• Fuel made from air! 18 Jun 2018 (Forum)
  4 The hydrogen and CO2 are then combined in two chemical processes, the first creates syngas, the second creates the synthetic fuel. 5 This can then be burned as is or blended with conventional fossil fuel. A boffin involved with the project estimates that 770 square mile plant in the Sahara Desert could supply Europes transportation needs.
• Jaguar X-Type Estate (2004 - 2007) - 04 2.0D Engine cuts out..... 20 Oct 2017 (Forum)
  I have VCDS, the VAG diagnostic software which also does OBDII on many other makes, but it will not communicate with this. I removed the fuel hoses from the fuel filter and drew fuel up with a hand primer. No problem there. I got him to crank the engine while I forced fuel on to the main injection pump and it still would not start. That makes me suspect that the main fuel pump could be faulty, or some other sensor which leads to the ECU switching the pump off.
• All makes and models - Possibly the end of the fuel debate? 20 Mar 2017 (Forum)
  Afternoon all - last week i picked up a tanker driver from the grangemouth refinary where he collects fuel for shell and formally BP. I thought he would be the perfect man to talk to about different fuels and indeed he was! We spent the entire taxi journey taking about the fuels and I asked him if the truth about supermarket fuels is true, his answer was simply what do I think I'm the one doing 50k a year.
