Diesel Exhaust Fluid


Diesel Exhaust Fluid

About DEF and SCR

Diesel Exhaust Fluid consists of high purity urea (typically crystalline) that is dissolved and suspended in de-ionized water. The approximate ratio of the mixture is 32.5% urea and 67.5% de-ionized water. DEF is not a fuel additive and must be filled into the dedicated Diesel Exhaust Fluid tank on your diesel vehicle.

When DEF is used with Selective Catalytic Reduction system, it helps reduce the amount of NOx emissions. The reduction in emissions is required to meet the EPA published Tier 2 Emission Standards for Light Duty and Heavy-Duty Vehicles. This standard regulates new strict emission control that began January 1, 2010.


DEF Benefits

Reduce Pollution

One of the leading causes of air pollution are NOx emissions.

DEF main job is to break down the nitrogen Oxide (NOx) gases into nitrogen and water to be safely release into the atmosphere.

Better Efficiency

Truck manufacturers using SCR system can be worried free when it come to design engines. Having this system allows them to focus on performance making sure that SCR system will take care of the emissions. Trucks manufacturers not using SCR systems need to redesign and compromise performance in order to reduce emissions.

Reduced Maintenance

The combination of DEF and SCR allows the manufacturers to focus on performance and to get rid of pollutants making the engines to run better. Your vehicle will have better fuel economy, increased power, decrease in vehicle maintenance and less wear and tear on your engine.

Maximize Fuel Efficiency

DEF and SCR technology combine, not only reduces NOx emissions it essentially improves a vehicle’s horsepower.

Making diesel engines to run more efficiently, resulting in fuel savings.



Our Diesel Exhaust Fluid is API Certified


The API Diesel Exhaust Fluid (DEF) Certification Program is a voluntary and was created to monitor the quality and characteristics of DEF (Diesel Exhaust Fluid) intended for use in motor vehicles with diesel engines.

This certification allowed marketers to demonstrated their DEF satisfy the requirements of the API (American Petroleum Institute) and the most recent and applicable edition of ISO 22241 Diesel engines – NOx reduction agent AUS 32, may be licensed to display the API Diesel Exhaust Fluid Certification Mark.

We offer a variety of ways to purchase DEF including 2.5-gallon jugs, 55-gallon barrels, 330 gallon totes and by the truckload.
