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.

Champion RV & Marine Antifreeze is specifically formulated for winterizing potable (drinking) water plumbing systems in recreational vehicles, vacation homes, trailers, boats and more.  This product is considered GRAS (Generally Recognized as Safe) by the Food and Drug Administration.
