Diesel Exhaust Fluid is known as DEF or AdBlue as well. DEF is a non-hazardous solution of deionized water and urea that turns nitrous oxide emissions of diesel vehicles into harmless ones (nitrogen and water).
This procedure is called SCR or Selective Catalytic Reduction. It not only can control pollution but also affects fuel consummation and optimizes engine performance.

DEF Specification
To get more information about the chemical and physical properties of DEF Diesel Exhaust Fluid, Look at the following table.
| Name | AdBlue, AUS (aqueous urea solution), DEF |

32.5% DEF or 40% DEF?
AdBlue fluid is typically made with 32.5% urea and 67.5% deionized water which is called AUS 32. But it is not the only type of diesel exhaust fluid that is supplied. AUS 40 is the other type that is often known as “marine DEF”.
Although 32.5% DEF is much more common, the AUS 40 is practical for vessels and even for locomotives as well. Look at the table below to see the difference between AUS 32 and AUS 40.
| AUS 32 | AUS 40 |
| Decrease nitrogen oxide (NOx) emission from the diesel exhaust system. | Decrease nitrogen oxide (NOx) emission from the water-based craft (known as marine DEF) |
| AUS 32 is made with 32.5% urea and 67.5% deionized water | AUS 40 is made with 40% urea and 60% deionized water |
What are the benefits of using DEF?
- Decrease the DEF emissions or mono-nitrogen oxide from diesel vehicles
- Allow you to introduce your business or company as an eco-friendly provider
- reduce fuel consumption
- decrease fleet costs
- optimizes engine performance
- operate more efficiently
Where can I buy Diesel Exhaust Fluid?
Azure is southern California’s DEF leader that wants to help you fulfill your handling and storage ambitions. No matter what you are looking for, we deliver our products in bulk DEF solutions, mini-bulk storage, or a diesel exhaust fluid tank for a diesel fleet.
Take care of universal health by using DEF!
As we said, DEF is sprayed into the exhaust stream of some fleets to reduce nitrous oxide (NOx) diesel emissions and break them down into harmless ones. Acid rain and smog are caused by NOx that may have irreparable consequences!
Be sure, blue DEF on diesel is the key to creating a better planet. So we are proud that Azure DEF diesel takes a leading part in it.
How much should I pay for Diesel Exhaust Fluid?
The price of AdBlue diesel depends on different criteria like the amount of solution that you buy, location, and supply method. Azure offers several packaging and delivery options such as:
- to 275 to 330 gallons IBC totes
- 2.5-gallon Jugs
- 55-gallon drums
- to 1000 to 6000-gallon tank truck
Based on the different flexible options, the DEF cost is variable as well. So if you want to get more information about the best blue diesel DEF fluid price, call us.
Conclusion
It is notable for public transport companies, businesses with diesel fleets, and manufacturers of diesel cars to be aware of DEF and its advantages. It helps them to have a vital role in universal health.
