Why buy AdBlue® in bulk?
- More convenient for organisations that operate large fleets or simply prefer fewer deliveries/invoices every year
- Remote sites are more at risk from supply shortages – an on-site storage tank provides peace of mind that you’ve got enough to see you through until your next delivery
- More cost-effective – not only due to price per litre but also through fewer deliveries, fewer packaging requirements and the time associated with tracking, ordering and receiving smaller drums
- Telemetry systems can be installed in bulk tanks to enable remote monitoring of AdBlue® levels, ensuring you never run out unexpectedly
How much AdBlue® does your fleet need?
AdBlue® consumption varies depending on vehicle type, engine specifications and operating conditions. As a general guide, it typically ranges from 2–6% of diesel usage, with heavier-duty vehicles generally requiring more than light-duty vehicles.
| Diesel consumed | Light-duty (3%) | Medium-duty (5%) | Heavy-duty (6%) |
|---|---|---|---|
| 500 litres | 15 litres | 25 litres | 30 litres |
| 1,000 litres | 30 litres | 50 litres | 60 litres |
| 2,500 litres | 75 litres | 125 litres | 150 litres |
| 5,000 litres | 150 litres | 250 litres | 300 litres |
| 10,000 litres | 300 litres | 500 litres | 600 litres |
The figures above are indicative estimates for guidance only. Actual consumption varies by vehicle, engine, load and operating conditions. Check the vehicle manufacturer’s guidance when planning your AdBlue® requirements.

Commonly asked questions about AdBlue®
What is AdBlue®?
AdBlue® is the common name used for AUS 32 diesel exhaust fluid (DEF), the diesel fuel exhaust fluid that has been introduced to help eliminate the harmful exhaust emissions released by heavy vehicles used daily on our roads.
Using AdBlue® is an effective means to reduce NOx emissions from diesel engines as it simply requires the addition of the fluid to your vehicle’s AdBlue® tank.
As of October 2006, the use of the DEF in modern diesel vehicles fitted with SCR technology, including both passenger cars and HGVs above 7.5 tonnes (industrial vehicles, buses and trucks) has become a legal requirement to help achieve the UK Government’s net-zero carbon-reduction target by 2050.
As an official AdBlue® supplier, Crown Oil can supply it at a competitive price in any quantity from 10 litres up to 5,000 litres. To purchase AdBlue® from a supplier you can trust, choose Crown Oil.
Is all AdBlue® the same?
As long as the diesel exhaust fluid you buy is certified to meet the AUS 32 criteria and meets ISO 22241, then there is no difference between which brand you use.

How much does AdBlue® cost?
As is the case with most bulk deliveries, the price of AdBlue® will depend on several factors, including the amount you’re ordering and the location we’re delivering to. Regardless, our AdBlue® quotes are among the most competitive on the market, and we’ll always aim to get you the best price for your AdBlue® diesel engine fluid.
If you have any more questions about AdBlue® or need any help, speak to one of our fuel experts to request a quote and place an order.
How do I store AdBlue®?
While storing AdBlue® is straightforward, it must be kept between -11oC and 30oC to maximise its 12-month lifespan. As well as supplying a wide range of fuel storage tanks, we can also provide storage tanks for AdBlue® to safely store it, in addition to both hand and electric pump options depending on your requirements.
Since AdBlue® is corrosive, these pumps make the dispensing process easier and safer, but you should always ensure you’re using it with care and be sure to wash your hands thoroughly after contact.
What happens if my vehicle runs out of AdBlue®?
Typically, before running out, a warning light will go off on your dashboard to indicate you are low on diesel engine fluid. However, once your vehicle runs out of AdBlue® it simply won’t start, as the emissions that would be released from the engine would be too high.
Can Crown Oil supply diesel and AdBlue® together?
Yes, you can absolutely order diesel and AdBlue® together for added convenience. As they require separate tankers, your account manager will coordinate both deliveries with you to arrange a time and day that suits your business.
If you have any questions about AdBlue® or would like a free, no obligation quote, speak to one of our fuel experts by calling 0330 123 1444 today.
