Fleetmaster CI-4 Plus 15W/40 is engineered with cutting-edge synthetic technology and tailored to withstand the rugged conditions. Its advanced high dispersant and anti-wear formulation are purpose-built to meet the stringent requirements of the latest low-emission US engines equipped with cooled Exhaust Gas Recirculation (EGR) systems, as well as Caterpillar ACERT engines.

This diesel engine oil not only complies with international standards for superior performance and extended service life in both turbocharged and naturally aspirated four-stroke diesel engines but also plays a crucial role in reducing soot buildup in modern low-emission US engines.

Fleetmaster CI-4 Plus 15W/40 features a unique formulation designed to set the highest standards for engine cleanliness, particularly in high-stress turbocharged engines. It effectively manages and suppresses bore polishing tendencies, curbing excessive oil consumption rates, and mitigating premature wear.

The outstanding performance of Fleetmaster CI-4 Plus 15W/40 extends to minimizing the formation of detrimental deposits in critical areas like ring grooves and land regions, with a specialized focus on the quench top ring belt zones, which are commonly found in “tight piston” engines.

A well-balanced blend of over-based alkaline reserve additives (TBN additive) within Fleetmaster CI-4 Plus 15W/40 proficiently neutralizes the acidic by-products stemming from the sulfur content in diesel fuel. This action not only prevents the potentially catastrophic effects of these by-products on the oil but also reduces the risk of corrosion to vital engine components.
