AdBlue Diesel Exhaust Fluid (DEF) is used in diesel vehicles with Selective Catalytic Reduction (SCR) type exhaust systems. The fluid is directed into the exhaust system and reduces Nitrogen Oxide (NOx) emissions out the tailpipe.

This OEM 1.89L bottle of AdBlue DEF has a special opening that attaches to the AdBlue tank, which doubles as a funnel once the bottle is empty.

Can be used in diesel versions of certain BMW, Mercedes, and Porsche models.
