Understanding Hyundai DEF

Hyundai DEF is a non-toxic, colorless liquid composed of 32.5% urea and 67.5% deionized water. It is injected into the exhaust system of diesel vehicles equipped with Selective Catalytic Reduction (SCR) technology. This technology helps convert harmful nitrogen oxides (NOx) emissions into harmless nitrogen and water vapor, significantly reducing a vehicle’s environmental impact.

The Importance of Using the Right DEF

Using the correct DEF fluid is crucial for your Hyundai diesel vehicle. Hyundai DEF is formulated to meet the specific requirements of Hyundai’s SCR systems, ensuring optimal performance and longevity.

Using off-brand DEF fluids or fluids that do not meet the required ISO 22241 standard can damage the SCR system, potentially leading to costly repairs and reduced fuel efficiency.
