• NITROGEN IN CAR TYRES: What's the point of filling car tyres with Nitrogen? (FAQs)
  Formula 1 Grand prix racing have used Nitrogen for decades as the tyre pressures are so critical and nitrogen is a dry, inflammable gas. Standard compressed air, contains 78% Nitrogen, 21% Oxygen and 1% other gases. It also contains water, both in free form and as vapour.
• ADBLUE: What is AdBlue and What do I need to know about it? (FAQs)
  The science involves miniscule amounts of Adblue added to the exhaust gases coming from the engine, and inside the high temperatures of the Selective Catalytic Reduction (SCR) catalyst the AdBlue turns into ammonia and carbon dioxide. The ammonia reacts with the nitrogen oxides in the gases and are turned into nitrogen and water - neither of which are harmful. Disadvantages of AdBlue Adblue solution itself will freeze at -11̊˚C, therefore the storage tank of the vehicle for the Adblue will almost certainly have to be heated to ensure the ambient temperature doesn’t drop below -10˚C.
• MISFUELLING A CAR: What should you do if you accidentally put the wrong fuel in your car?  (FAQs)
  AdBlue is a trade-name for the most popular Diesel Exhaust Fluid (DEF), now used in many modern diesel vehicles to reduce the amount of nitrogen oxides created by diesel combustion. It is composed of deionised water and urea and works by mixing with exhaust fumes to change them from nitrous oxide (NO2) to harmless nitrogen, water and carbon dioxide.
