General Motors (GM) vehicles that require Diesel Exhaust Fluid (DEF) typically use a standard DEF that meets the ISO 22241 specification, which is a common standard across the industry. This DEF is often branded as ACDelco DEF for GM vehicles, ensuring compatibility and optimal performance with their diesel engines. Always refer to the vehicle's owner's manual for specific recommendations and requirements.
