ROLF OPTIMA SAE 40 API CF / SF high-quality seasonal engine oil for diesel engines consists of high-quality base oil with the addition of a unique package of additives, ensures efficient operation of the engine in severe operating conditions. It is designed for use in supercharged engines with intermediate air cooling, working in difficult conditions and off-road.
ROLF OPTIMA SAE 40 API CF / SF is recommended for use in diesel engines of early years of release with high mileage. The usage of the oil prolongs their life and provides excellent protection. Intended for use in engines of vehicles that are operated in the southern regions, where the use of seasonal oils is recommended. ROLF OPTIMA SAE 40 oil is recommended for use in heavy trucks, road and off-road vehicles, which oil specifications API CF or earlier are recommended for. The excellent washing and neutralizing ability guarantees the maximum protection of the engine against corrosion and the formation of high-temperature deposits. The oil provides the cleanliness of the engine parts and protection against wear throughout the life of the oil. High thermal-oxidative stability prevents the aging of the oil under high temperatures conditions.
• Provides effective engine protection, prevents wear of cylinder-piston group, protects against oxidation, corrosion and the formation of soot deposit on the inner surfaces of the engine.
• It has excellent antioxidative, dispersing, washing, neutralizing, antiwear properties.
• Reduced oil consumption for waste.
• Great for use on heavy duty engines.
