-Diesel Exhaust Fluid (DEF) is an organic, non-toxic compound made of 32.5% urea and 67.5% de-ionized water
-DEF is carefully regulated by the American Petroluem Institute (API)
-DEF helps to convert NOx into Nitrogen gas and water vapor. It is stable, colorless, odorless, and meets accepted internatioal standards for purity and composition
-2.5 Gallons of DEF will yield over 800 miles of travel
-You can drive from L.A. to Boston and back on less than a single 23-gallon tank of DEF (estimated usage rate is approximately 2% per gallon of fuel)
-At temperatures below 12°F (at which DEF will freeze) trucks will be immediately operational until the DEF tank-thawing process is complete
-The DEF filter should only need to be changed every 200,000 miles and can be changed in minutes
-With Selective Catalytic Reduction (SCR), engine maintenance intervals will remain equal to 2007 maintenance intervals, with one additional service point: The DEF filter
