Oilzum DEF: Choice of Champions
DEF (Diesel Exhaust Fluid) is a liquid that helps to reduce air pollution from diesel engines. Our DEF consists of 32.5% urea and 67.5% deionized water. Its main function is to break down the nitrogen oxides in the exhaust to generate cleaner emissions.
In the mid 2000’s, DEF broke into the United States in hopes of reducing diesel engine emissions. Today, the EPA mandates that all medium to large vehicles with diesel engines must have integrated DEF technology. Ensure that your diesel vehicle meets emissions regulations with a time tested name in the automotive and heavy duty industry. Oilzum Clean Air DEF is the choice of champions across all industries.
