What is blue def?

Blue Def is a brand of diesel exhaust fluid (DEF) used in diesel-powered vehicles equipped with selective catalytic reduction (SCR) systems. DEF is a non-toxic, colorless fluid composed of 32.5% urea and 67.5% deionized water that helps reduce harmful nitrogen oxide emissions produced by diesel engines.

Blue Def is formulated to meet the strict specifications set by the American Petroleum Institute (API) and the International Organization for Standardization (ISO) for DEF quality. It is also certified by the German Association of the Automotive Industry (VDA) and the American Petroleum Institute (API).

When used in conjunction with a SCR system, Blue Def helps convert harmful nitrogen oxides into harmless nitrogen and water vapor, resulting in cleaner emissions and improved air quality.

Blue Def is available for purchase in various sizes, including jugs, drums, and totes, making it convenient for consumers to refill their DEF tanks as needed. It is essential for diesel vehicle owners to use a high-quality DEF like Blue Def to ensure optimal performance and compliance with emissions standards.
