Understand how much AdBlue® your vehicle or fleet requires with our handy guide. By understanding your consumption rates, you can better plan your AdBlue® purchases and potentially save yourself or your business money. 

Car AdBlue® consumption

Wondering how much AdBlue® your car needs? Most Car AdBlue® Selective Catalytic Reduction (SCR) systems and tanks are designed to last between service intervals, so it’s unlikely you’ll need to top it up yourself.  

Nevertheless, if you do begin to run out – as shown by an amber warning light on your dashboard – and you want to refill yourself, learn how to check, refill and remove AdBlue® in our handy guide. 

Commercial vehicle AdBlue® consumption

AdBlue® use in commercial vehicles depends on the tonnage of vehicle, with use rates ranging from 3 to 6% of diesel consumption.

Machinery AdBlue® consumption

AdBlue® consumption in diesel-powered machinery and off-road vehicles is dependent on a wide range of factors, including engine size, usage and operating conditions. For more information on how much AdBlue® your machinery is likely to use, contact the manufacturer or consult your owner’s manual. 

Bus and coach AdBlue® consumption

Bus consumption of AdBlue® usually equates to around 5% of diesel consumption, although the amount used will be dependent on the mileage of the vehicle: generally, city buses will use 20 to 30 litres each month, compared to 40 litres per month for buses operating over longer, cross-country routes.
