Fleetmaster CI-4 15W/40 is a robust SAE 15W/40 diesel engine oil that not only adheres to international standards for exceptional performance but also boasts a prolonged service life, making it an ideal choice for both turbocharged and naturally aspirated four-stroke diesel engines. This exceptional oil is engineered to meet the exacting requirements of the latest generation of cooled Exhaust Gas Recirculation (EGR) engines.

What sets Fleetmaster CI-4 15W/40 apart is its unique formulation, meticulously crafted to uphold the highest standards of engine cleanliness, especially in modern, high-stress turbocharged engines. It excels in controlling and preventing bore polishing tendencies, mitigating excessive oil consumption rates, and delaying premature wear.

The outstanding performance of Fleetmaster CI-4 15W/40 plays a pivotal role in curbing the formation of detrimental deposits in critical areas like ring grooves and land regions, with a particular focus on the quench top ring belt zones typically found in “tight piston” engines.

A specialized balance of over-based alkaline reserve additives (TBN additive) within Fleetmaster CI-4 15W/40 effectively neutralizes the acidic by-products generated by the sulfur content in diesel fuel. This action not only reduces corrosion risks to vital engine components but also prevents the potentially catastrophic impact these by-products can have on the oil.

Fleetmaster CI-4 15W/40 is tailor-made for the harsh operating conditions. It incorporates special polymers that help maintain viscosity at elevated operating temperatures, ensuring that maximum oil pressures are consistently upheld. This makes it an exceptional choice for engines subjected to demanding conditions.
