General Motors (GM) typically uses Diesel Exhaust Fluid (DEF) that meets the ISO 22241 standard for their diesel vehicles, which is a requirement for most DEF products. While GM does not specify a particular brand, they recommend using DEF that adheres to this standard to ensure proper functioning of the Selective Catalytic Reduction (SCR) system. It's always a good idea to consult your vehicle's owner manual for any specific recommendations or requirements.
