Diesel exhaust fluid (DEF) is a type of urea-based solution used in diesel engines to reduce the amount of harmful emissions they produce. It works by breaking down nitrogen oxide emissions into harmless nitrogen and water vapor when injected into the exhaust system. DEF is colorless, odorless, non-flammable, and biodegradable, making it an environmentally friendly choice for reducing air pollution from diesel engines. It also helps to reduce engine wear and reduce overall fuel consumption.

DEF is the key to keeping your diesel engine running clean.

DEF is an odorless, colorless, and non-toxic liquid that helps reduce harmful emissions from diesel engines. It’s a vital part of keeping your engine running smoothly and reducing air pollution.

Diesel Exhaust Fluid keeps your engine running clean and lasting longer, while also being environmentally friendly.

What is DEF?
Do all Diesel Engines need Exhaust Fluid?

Some modern diesel engines are designed to operate without DEF by using different technologies such as exhaust gas recirculation (EGR) or cooled exhaust gas recirculation (CER). But most modern diesels are equipped with Selective Catalytic Converters (SLR) and require DEF.

How Often do you put DEF in a Diesel?

Light duty trucks and machinery use around 2-3 gallons per 800 miles. But, that range increases to 5,000+ miles with newer, efficient diesel trucks. Typically, DEF burns at an approximate rate of 2% of the fuel burn. So for every 100 gallons, DEF will burn 2 gallons.
