What is DEF? (Diesel Exhaust Fluid)
DEF is a naturally occurring compound of nitrogen that is primarily produced from natural gas and turns into ammonia when heated. It is used in a number of industries, most commonly as a fertilizer for agriculture.
Automotive-grade DEF is used as a carrying agent for the ammonia needed to reduce nitrogen oxide emissions from vehicles by converting them to nitrogen, water and carbon dioxide. DEF is stable, non-toxic, odourless, and completely safe. It optimizes the performance and efficiency of your engine, and continues to perform at the wide range of climate temperatures.
