Diesel exhaust fluid

Diesel Exhaust Fluid, or DEF, is crucial for modern diesel vehicles. We're breaking down everything you need to know about its use and importance.So, what exactly is DEF? It's a mixture of urea and deionized water, vital for reducing harmful emissions and meeting environmental regulations in diesel vehicles.Selective Catalytic Reduction, or SCR technology, uses DEF to transform harmful emissions into harmless nitrogen gas and water vapor. This significantly improves air quality.DEF consumption varies, but most modern diesel vehicles require it. Typically, you'll use about one gallon of DEF for every 200 miles driven.Running out of DEF can lead to non-compliance with emission regulations. Vehicles alert drivers when levels are low, requiring immediate refilling to maintain environmental standards.Small DEF spills can be washed away, while large spills require contacting your supplier for guidance. DEF has a two-year shelf life, but avoid direct sunlight.DEF is non-flammable and non-toxic, and it can actually improve fuel economy by about 5%. We need to refill the DEF tank every 5,000-6,000 miles.
