Diesel Exhaust Fluid: What Is It and Why Does It Matter?

Not all diesel exhaust fluids (or suppliers) are created equal.

There are a number of factors worth considering before making your next DEF purchase. Examples include certainty over industry standards, including API and ISO requirements, manufacturing and performance quality, as well as convenient delivery options and competitive pricing.

What is Diesel Exhaust Fluid?

DEF is a non-toxic, non-flammable, non-hazardous, and non-explosive water-urea solution (32.5% high-purity urea and 67.5% deionized water).

What Does Diesel Exhaust Fluid Do?

The purpose of DEF is to reduce nitrogen oxide (NOx) concentration in the exhaust emissions produced by diesel engines.

DEF is generally carried in a separate storage container or tank in diesel-powered vehicles and is then injected into the hot exhaust stream of an engine. This process helps to break down the NOx gases in the exhaust and turn them into nitrogen gas and water vapor—which are harmless to the environment.

Who Should Use Diesel Exhaust Fluid?

In 2010, the U.S. Environmental Protection Agency issued NOx emission standards for all diesel vehicles, irrespective of size. As a result, most light-duty and heavy-duty trucks, as well as stationary and heavy equipment, will need to use DEF. Additionally, other diesel engine powered vehicles and equipment, like pickup trucks, SUVs and forklifts require DEF, too.

What are the Advantages of Diesel Exhaust Fluid?

The EPA emission standards are strictly enforced and using DEF provides several benefits to the environment, including reducing smog and air pollution.

In addition to meeting industry-related emission standards, DEF can also provide fuel savings. Industry research shows that a fleet of heavy-duty trucks using EPA-compliant engines and DEF could experience nearly 5% fuel savings when compared to vehicles with similar, non-compliant diesel engines made prior to 2007.

How Can I Save Money?

One of the best ways to save on DEF is to order fluid in bulk. This option is a significantly cheaper, and more simple procedure than purchasing individual containers to haul back to your facility.
