Caltex Havoline ProDS (5W-40)-4L is engineered for maximum engine life, power, and performance across a wide temperature range. Its advanced anti-wear additives reduce friction and protect even the most sophisticated valve train systems, while metallic detergents keep engines clean under severe conditions. With reduced metal, phosphorus, and sulfur levels, it lowers emissions, protects catalytic converters and diesel particulate filters, and minimizes maintenance costs. The synthetic, shear-stable formula also ensures low oil consumption and consistent viscosity for lasting engine protection and efficiency.
