PEAK® Commercial & Industrial products have been trusted by people all over the world, for over 65 years, to keep their vehicles and equipment running.

Today’s diesel engines are more fuel efficient and environmentally friendly. Part of this improvement is due to a Selective Catalytic Reduction (SCR) system. Located in the engine’s exhaust stream, the SCR system reduces harmful elements in the exhaust and helps to improve fuel economy. SCR systems require a fluid called diesel exhaust fluid (DEF), a mixture of high-grade urea and deionized water.

BlueDEF™ Diesel Exhaust Fluid is manufactured with the highest-quality ingredients and under strict guidelines to ensure the DEF you get is the purest DEF you can buy. BlueDEF™ Diesel Exhaust Fluid contains no chemical additives or other compounds that could cause SCR system failure.

Works in all diesel vehicles and equipment with SCR systems. Non-toxic, non-flammable formula makes handling safe and easy. Manufactured under ISO 22241 guidelines, combining high-quality automotive grade urea with deionized water and certified by the American Petroleum Institute ensures product purity.

67.5% Water (7732-18-5), 32.5% Urea (57-13-6).
