Diesel Engine Oil SAE 40 (API CF/SF) is a dependable monograde heavy-duty diesel engine oil formulated using selected base oils and a balanced additive system designed to provide reliable lubrication and protection for engines operating under moderate to severe conditions.

The formulation provides resistance against wear, oxidation, and thermal degradation while maintaining stable viscosity and basic deposit control. It is suitable for use with high sulfur fuels when applied with appropriate oil drain intervals, supported by its alkalinity reserve for acid neutralization.

This product is designed for use in older-generation diesel engines, including naturally aspirated and turbocharged units, where API CF/SF performance level lubricants are specified.
