SCR technology and the use of AdBlue ® is becoming more and more common for cars in Europe, in order to meet the emission standards set with Euro 6 introduction in 2014. The manufacturers that have already introduced models equipped with SCR technology are: Renault, Peugeot, Citroën, Volkswagen, Audi, BMW, Mercedes Benz, GM / Opel, Ford, Toyota and Mazda.
Where is AdBlue for cars available?
The AdBlue ® tank of the car will be filled up during the scheduled maintenance. In case a car runs out of AdBlue ® it’s possible to find special bottles for sale at gas stations with a patented safe connection to fill the tank.
In most cases the equipment at gas stations and truck stops is only compatible with commercial vehicles, as the nozzle is too big to fill cars.
Should I avoid buying a car equpped with SCR Technology that requires AdBlue ®?
Absolutely not. SCR Technology is the most effective way to reduce NOx emissions in the atmosphere. The car is normally a little bit more expensive compared to the same version equipped with standard engine, but SCR Technology grants much better fuel efficiency. Also consider that the price of AdBlue is very low, with very little impact on car maintenance costs. It’s definitely a long lasting investment.
What happens to the car when AdBlue ® level is low / AdBlue ® is missing?
SCR cars are equipped with a special warning system that notifies of low AdBlue ® fluid levels. The AdBlue ® supply needs to be replenished approximately once every 15.000 km (10,000 miles), depending on the car model and driving style and conditions. In case your vehicle requires additional AdBlue ®, your instrument panel will begin warning you with sound and detailed instructions, usually when 2.500 km (1,500 miles), 1.000 km (600 miles) and limited km / miles remain. When the AdBlue ® tank is completely empty the engine will not restart if shut down.
