What In The World Is BLUE DEF?

No, it not the latest energy drink, Diesel Exhaust Fluid 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, instead its injected into the exhaust system to reduce air pollution.

When injected into the exhaust stream and passed over a catalyst, Diesel Exhaust Fluid helps convert NOx into nitrogen gas and water vapor – two harmless and natural components of the atmosphere, reducing pollution from diesel powered trucks.

BlueDEF is stored in a dedicated tank next to the fuel tank on the driver’s side. The tanks range in size from 6 to 23 gallons depending on the truck’s application.

The next time you visit your local Home Depot check out the Blue Def, its helping make the air we breathe cleaner every day.
