The amount of AdBlue required by your vehicle will depend on how the car is driven, but also the size of the tank fitted to your vehicle as both 12-litre and 24-litre AdBlue tanks were available when new. The harder the engine is working, the more AdBlue that will be consumed in order to reduce exhaust emissions, so city driving or towing will result in greater consumption, while steady motorway driving will result in lower consumption. You should expect to travel between 5,000 and 10,000 miles depending on driving style and the size of the AdBlue tank.

When purchasing AdBlue it is important to use a reputable retailer and ensure it carries the registered trademark symbol, indicating it is the correct formulation for use in passenger vehicles.
