Yes, it does matter what brand of diesel exhaust fluid (DEF) you use. While most DEF products meet the same industry standards, ensuring they are ISO 22241 certified is crucial to prevent potential damage to the Selective Catalytic Reduction (SCR) system. Using a reputable brand can also provide assurance of quality and consistency, reducing the risk of contaminants that could harm your vehicle's emissions system.
