Cleaner Emissions, Better Performance

Diesel Exhaust Fluid (DEF) is a non-hazardous, non-toxic solution used in Selective Catalytic Reduction (SCR) systems to help reduce harmful emissions from diesel engines. Made of 32.5% urea and 67.5% deionized water, it converts nitrogen oxides into harmless nitrogen and water vapor—supporting cleaner emissions and better engine performance.

Pilot offers DEF at all of its locations nationwide, with dedicated onboard vehicle tanks that make refills easy and accessible whenever needed.
