DEF Helps Diesel Engines Meet New EPA Regulations

DEF Helps Diesel Engines Meet New EPA Regulations

In January 2010, the U.S. Environmental Protection Agency (EPA) introduced new emissions standards requiring medium- and heavy-duty vehicles to significantly reduce engine emissions.

Diesel Exhaust Fluid (DEF) is a non-hazardous chemical solution containing urea and deionized water, and is used to break down dangerous NOx emissions into nitrogen and water.

DEF works together with Selective Catalyic Reduction (SRC) technology to help equipment meet emissions regulations. DEF is a versatile fluid, with a relatively long shelf life that is still effective even if it becomes frozen.

As a result most new diesel trucks, pickups, SUVs, and vans are now fitted with SCR technology and have a DEF tank that must be regularly refilled.

When it comes to purchasing DEF, Bear Oil Company recommends the TerraCair brand for quality and consistency of product.  The same supplier makes TerraCair DEF every time, with a regulated transportation process ensuring ideal temperature during transport for a longer shelf life.
