Servo Ultra KB 10 is a premium-grade heavy-duty diesel engine oil specially designed for use in high-performance diesel engines operating under severe and demanding conditions. It is formulated with high-quality, high-viscosity index base oils and a carefully balanced additive package containing detergents, dispersants, antioxidants, and anti-wear agents to ensure reliable protection and long-lasting performance. The oil effectively minimizes sludge and deposit formation caused by high-sulfur fuels and combustion residues, maintaining superior engine cleanliness and efficiency even during extended drain intervals. Its excellent oxidation stability ensures consistent viscosity control and prevents oil thickening under high-temperature operating conditions, making it ideal for both on-road and off-road applications. Servo Ultra KB 10 provides exceptional wear protection, reducing engine component wear and corrosion in all types of turbocharged and naturally aspirated diesel engines. Its superior detergent and dispersant characteristics help keep piston rings, valves, and filters free from deposits, enhancing overall engine reliability and extending service life. Recommended for diesel engines of earthmoving, construction, and industrial equipment, the oil is especially suitable for Caterpillar machinery, Bharat Earth Movers (BEML) vehicles, and other high-speed, high-output diesel engines. It can also be used in transmission systems where similar performance levels are required. With a high flash point for thermal stability and a low pour point ensuring easy cold starts, Servo Ultra KB 10 offers reliable performance across a wide range of operating temperatures. Meeting the performance level of API CD and US MIL-L-45199B specifications, Servo Ultra KB 10 guarantees excellent control over oil consumption, reduced maintenance costs, and extended engine life — making it the trusted choice for operators who demand consistent performance and durability from their equipment.
