Diesel Exhaust Fluid (DEF) is a nontoxic, colorless and odorless solution of 67.5% purified water and 32.5% ultra-pure automotive grade urea that is API Certified and complies with ISO 22241-1.

When injected into the exhaust stream (a process known as selective catalytic reduction, or SCR), DEF eliminates 90% of exhaust pollutants by converting them to nitrogen and water.  Tier 2 Bin 5 emissions standards currently require all new diesel vehicles on U.S. highways to comply with stricter emissions standards set forth by the Environmental Protection Agency (EPA).
