PSO DEO 3000 SAE 50 – Extra Heavy Duty Monograde Engine Oil | API CF/SF (4 Liters)

PSO DEO 3000 SAE 50 is a high-viscosity monograde lubricant specifically engineered for diesel engines operating under severe conditions and high ambient temperatures. This “thick” oil provides a superior seal for worn engine components and maintains its film strength under heavy loads. It is the go-to solution for engines that require maximum protection against heat-induced oil thinning.

Key Benefits

• Maximum Film Strength: The SAE 50 grade is significantly thicker than standard oils. This creates a massive protective barrier between moving parts, which is essential for engines that have “looseness” or high mileage.

• Sealing Power: It acts as a liquid gasket. For older engines that might be “breathing” (smoke coming from the breather) or losing compression, this thick oil helps seal the piston rings to restore some power.

• Extreme Heat Stability: Ideal for the toughest Pakistani summers. It is designed not to turn “watery” even when the engine is working under the blazing sun for 12+ hours.

• Prevents Oil Leaks: Because of its high viscosity, it is less likely to seep through old seals and gaskets compared to thinner 15W-40 or SAE 40 oils.

• Corrosion Protection: Contains robust additives that protect engine internals from the high-sulfur diesel often used in agricultural and industrial sectors.

Technical Specifications
