DIESEL EXHAUST FLUID (DEF)

Diesel Exhaust Fluid (DEF)

Since 2010, emissions legislation now requires diesel vehicles to significantly reduce emissions and particulate matter (air pollution). We advise our customers to meet these standards by using Diesel Exhaust Fluid (DEF). DEF is a new product that can destroy harmful exhaust emissions, and is required by many heavy-duty trucks, pickups, SUVs and vans delivered after January 2010.

A non-hazardous liquid, DEF consists of 67.5% de-ionized water and 32.5% urea, and is used in combination with Selected Catalytic Reduction (SCR) technology. DEF is sprayed into the exhaust and combines with a catalyst to break down NOx (nitrogen oxides) into nitrogen and water. When NOx and volatile organic compounds (VOCs) react in the presence of sunlight, they form photochemical smog, a significant form of air pollution, especially in the summer.

SCR technology offers greater fuel efficiency, increased vehicle reliability and longer oil change intervals, which means greater savings for you.

As of 2011, a number of manufacturers of agricultural, construction and forestry equipment also use SCR and DEF in order to meet the EPA's stringent environmental standards.
