PEAK BlueDEF PEAK® BlueDEF™ Diesel Exhaust Fluid - 2.5 Gallon

Diesel Exhaust Fluid (DEF) is one of the key elements of the Selective Catalytic Reduction (SCR) process used by Diesel Engine builders to meet EPA 2010 regulations. BlueDEF® is a nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea. BlueDEF® is not a fuel or fuel additive.
