Champion Diesel Exhaust Fluid (DEF)

Champion Diesel Exhaust Fluid (DEF) is an API certified diesel exhaust fluid made of nontoxic solution of 67.5% purified water and 32.5% ultra pure automotive grade urea.  Champion DEF is not a fuel or a fuel additive.  Instead, when injected into the exhaust stream and passed over a catalyst, Champion DEF helps convert NOx into nitrogen gas and water vapor.

Available in 2.5 gallon or 55 gallon drum.
