• Nitrogen in Tyres 22 Mar 2013 (Forum)
  Anyone heard about using nitrogen in tyres instead of air? I have come across it in Europe before, but the idea seems to be rare here. A search on the web brings up http://www.merityre.co.uk/why_nitrogen.htm but does anyone know if any of the national chains offer it yet?
• Nitrogen Filled Tyres? 12 Aug 2003 (Forum)
  Hi All, Has anyone actual practical experience of nitorgen filled tyres? I know that some tyre retailers claim nitrogen keeps tyres inflated for longer thus enhancing tyre life, reducing fuel consumption and 'helping with vehicle handling' - whatever that last bit means. Seems to me it seems

• Diesels - are they taking the p**s? 27 Sep 2001 (Forum)

• Nitroinflate anyone ? 24 Jan 2007 (Forum)
  Hi. I have just had a couple of new tyres fitted and noticed I have been charged £2.50 for a "nitroinflate". Presumably they have inflated the tyres with nitrogen rather than air. I am not quibbling, just interest as to why ? I would imagine nitrogen would diffuse through rubber a little quicker
• PSA - More recalls 8 Dec 2023 (Forum)

  Oh dear, HJ seems to have got a bit confused here http://www.honestjohn.co.uk/askhj/answer/75465/is-putting-nitrogen-in-tyres-a-good-idea- I thought the only possible advantage of pure N2 as opposed to using air was that the oxygen might degrade the rubber (to a small extent
• EGR valve adjustment. Ford Transit 2.5Di 4 Oct 2012 (Forum)
  I have a 1998 Ford Transit, not a car I admit, but still a motor vehicle. It is fitted with the 2.5 DI non turbo-charged engine and comes as standard with an EGR valve (Exhaust Gas Re-Circulation) for the purpose of lowering exhaust gas temperature and hence reducing oxides of nitrogen therein

• New tyre pressures! 5 May 2009 (Forum)
  I had 4 new tyres fitted 2 weeks ago at an independent tyre firm in Derby. These tyres were filled with nitrogen and the fitter was told the correct pressures. I have just checked the pressures with 2 tyre gauges. One was 6psi under inflated, one was 4psi under, one was 3psi under and believe

  Hi, I've just had a leak in my A/C diagnosed via a nitrogen test as being on a small pipe between the condenser and drier (seen with my own eyes). I want to replace the condenser and drier myself and then take the system for evacuation/oil and gas recharge. Can any one advise if I need any
• Welding experts?? 10 May 2003 (Forum)
  as the car is worth. After £50 worth of trying they called a halt because nitrogen testing showed pinprick leakage through all three welds tried. The welder (from a different company) wasn't present to explain further. My question is whether there is a welding process that might provide a gas tight seal
• CAR EMISSIONS 25 Apr 2001 (Forum)
  , lorries, and taxis stand out as the major contributors to urban motor vehicle pollution. An older articulated lorry produces as much particulates as 350 new petrol cars and the nitrogen oxide of 284 new petrol cars. The current generation of petrol cars produces around one-sixteenth of the toxic urban
• USA wakes up to diesel cars ? 9 May 2007 (Forum)

Strategy Analytics predicts that once the new diesel fuel has been approved in the five ultra-low emissions states, which account for 37 percent of hybrid sales, "diesel will challenge hybrid vehicles for the more cost
