If you own a diesel car, then it is likely that at some point it will require an AdBlue top up.
AdBlue is a non-toxic solution which is made up of mixture of urea and deionized water. This solution is sprayed into a diesel engine’s exhaust system to help lower the nitrous oxide emissions of the vehicle.
When booking an AdBlue top up with Blackcircles.com your vehicle will receive a 10 litre refill.
If, on the day your vehicle does not require the full 10 litres, you will be given the remaining AdBlue solution to keep for future use.
