ABOUT product
High viscosity mineral diesel engine oil SAE (20W-50) designed for older diesel engines or units operating in very high ambient temperatures and with higher oil consumption. Recommended where thicker oil is required to reduce oil loss. Suitable for older commercial vehicles and heavy equipment without modern DPF systems, providing strong oil film strength under severe load and temperature conditions.
