Fleetmaster CI-4 15W/40 is an exceptional SAE 15W/40 diesel engine oil meticulously engineered to meet international standards, delivering outstanding performance and extended service life for both four-stroke turbocharged and naturally aspirated diesel engines.

This oil is tailor-made to meet the stringent performance requirements of the new generation of cooled Exhaust Gas Recirculation (EGR) engines. It boasts a unique formulation designed to uphold the highest standards of engine cleanliness, especially in modern, high-stress turbocharged engines. Fleetmaster CI-4 15W/40 is highly effective in controlling and preventing issues like bore polishing, excessive oil consumption, and premature wear.

One of its standout qualities is its ability to minimize the formation of harmful deposits in critical areas like ring grooves and, notably, the quench top ring belt regions of engines with tight pistons.

What sets Fleetmaster CI-4 15W/40 apart is its specialized blend of over-based alkaline reserve additives (TBN additives). These additives effectively neutralize the acidic by-products generated by diesel fuel’s sulfur content during combustion. This proactive measure reduces the corrosion risk to crucial engine components and mitigates the potentially disastrous impact these by-products can have on the oil.

Fleetmaster CI-4 15W/40 has been meticulously crafted for the demanding conditions. It incorporates special polymers that minimize viscosity reduction at high operating temperatures, ensuring that maximum oil pressure is consistently maintained even under challenging conditions. This makes it an ideal choice for vehicles operating in rugged environments.
