The misuse of AdBlue can result in problems which will immobilise vehicles and are costly to put right, although the additive itself is relatively inexpensive. Failing to take action when an AdBlue warning appears will result in the vehicle failing to start or breaking down.

Chief Operating Officer at Alphabet, Matt Sutherland, said;

“AdBlue is crucial to many engines in this next generation of diesel technology. It’s good news for fleet managers and drivers who benefit from improved efficiency and reduced emissions, but it’s important that fleet managers and diesel drivers understand what AdBlue is, what their responsibilities are and how to use it.

“Fleet Managers need to ensure that their organisation’s vehicle policy includes clear instructions around the use and misuse of AdBlue, in the same way that they do currently with mis-fuelling petrol with diesel or adding other fluids like oil. Similarly, some drivers depending on their driving style and the types of journeys they make, will require AdBlue top ups outside of their regular servicing so Fleet Managers need to consider their policy and how they handle that.

“For most company car drivers their tank of AdBlue will be filled up during the scheduled service and once filled up they shouldn’t have to worry for several thousands of miles or until the next service. LCVs or drivers who make lots of stop-start journeys are likely to require additional AdBlue top ups between services.

“Like engine oil or washer fluid, drivers need to be familiar with how to top up their vehicle with AdBlue and make sure the fluid is put in the right place according to their vehicle handbook. Similarly drivers have a responsibility to keep an eye on any dashboard AdBlue warnings and take the appropriate corrective action in accordance with their employer’s vehicle policy – otherwise the vehicle will come to a halt or won’t start next time.”
