EVERYTHING YOU ALWAYS WANTED TO KNOW ABOUT DEF

BUT YOU WERE AFRAID TO ASK!
What Is DEF?

DEF (Diesel Exhaust Fluid) is NOT a fuel additive and it is NOT put into the fuel tank of the vehicle. DEF is not subject to fuel tax in any other jurisdiction as it is not used to propel the vehicle and is not added to any fuel.

Why Do They Use DEF?

In 2010, new diesel trucks had to start meeting lower emission levels (maximum 2 grams per brake HP). The manufactures of new diesel cars and trucks started using what they call a SCR system which is short for Selective Catalytic Reduction. All manufacturers except Navistar have begun using the SCR system.
