AdBlue has become essential for modern diesel vehicles - especially commercial fleets, logistics providers, agriculture, and heavy machinery operators. This guide explains what AdBlue is, how it works, and where to buy Bulk AdBlue for your business, along with key storage, pricing and supply information.
AdBlue is a high-purity liquid made from 32.5% urea and 67.5% deionised water, used in diesel engines with SCR (Selective Catalytic Reduction) systems to reduce nitrogen oxide (NOx) emissions.
It is:
The SCR system injects AdBlue into the exhaust stream, where it breaks down into ammonia. This reacts with NOx in the catalyst, converting harmful emissions into nitrogen and water vapour—making the vehicle compliant with Euro 5 and Euro 6 standards.
AdBlue is used by a wide range of diesel-powered vehicles:
HGVs consume the highest volumes due to continuous operation.
Typical consumption levels:
Vehicle Type - Usage
Cars - 1–2L per 1,000 miles
Vans - 3–5% of diesel use
HGVs - 4–8% of diesel use
Tractors - Varies by load
Budget 1L of AdBlue per 20L of diesel burned.
Buying AdBlue in bulk provides major cost and operational advantages.
