But poor air quality has also been a concern for many years and nitrogen oxide (NOx) emitted from the exhausts of diesel cars is one of the big culprits. Some sources claim AdBlue is corrosive and should be handled with care, while others claim it’s harmless. The first clue that your car is running low on AdBlue is that you’ll see a warning light in the instrument cluster. At high temperatures, AdBlue turns into ammonia, in the process breaking down NOx into its component chemicals – nitrogen and oxygen – which are completely harmless on their own.

If you turn your car’s engine off when the AdBlue has run dry, it may not start until the tank has been replenished. A diesel pump nozzle is too big to fit in the AdBlue filler, however it is possible to accidentally put AdBlue in your diesel tank. Euro 6 emissions regulations heavily clamped down NOx emissions and many car manufacturers employ AdBlue technology to meet the standards. Reduce harmful nitrogen oxide emissions produced by diesel engines by adding the appropriate amount of Carlube AdBlue 10 Litres to your car’s dedicated AdBlue tank.A diesel Volkswagen Passat, for instance, takes about 8,000 miles to empty its 13-litre AdBlue tank. This 10-litre container of Carlube AdBlue is ideal if you have a small car or do relatively low mileage.

The introduction of this clever but simple chemical is to aid car manufacturers in combating the ever-stricter emission targets. NOx is a waste product of the combustion process, along with carbon dioxide and many other chemicals.

Even stricter Euro 7 standards are due to be implemented in the second half of the 2020s but, until then, a large number of diesel cars currently on sale in the UK use AdBlue. AdBlue is an additional cost of car ownership, which is a bit annoying, but it’s not especially expensive and, as mentioned earlier, it lasts a very long time. AdBlue goes into a tank underneath your car and is injected into the exhaust system to remove NOx from the exhaust gases. The low AdBlue light generally comes on when there’s around 1,000 to 1,500 miles left in the tank, so you have plenty of time to top it up.In which case, a bigger, 20-litre container like this one from CleanAirBlue could save you some hassle. Other cars only need refilling with AdBlue when they’re serviced and, in these cars, the filler cap is usually under the boot floor. AdBlue doesn’t eliminate NOx emissions entirely, at least in part because the system only works when the exhaust gas has reached a very high temperature.
