Description
Fleetmaster CI-4 15W40 is a diesel engine oil which meets international specifications for top performance and long service life in four stroke turbo-charged and normally aspirated diesel engines.
Fleetmaster CI-4 15W40 is specifically designed to meet the performance levels required for the new generation of cooled EGR Engines. It is uniquely formulated to promote the highest standards of engine cleanliness in modern highly stressed turbocharged engines. It very effectively controls and inhibits bore polishing tendencies, high oil consumption rates and premature wear.
The excellent performance of Fleetmaster CI-4 15W40 minimises the formation of damaging deposits in ring grooves and land areas, particularly the quench top ring belt areas of ‘tight piston’ engines.
A special balance of over-based alkaline reserve additives (TBN additive) in Fleetmaster CI-4 15W40 effectively neutralises acidic combustion by-products caused by the sulphur content in diesel fuel. This reduces the corrosion of critical engine components and otherwise catastrophic effects these by-products have on the oil.
Fleetmaster CI-4 15W40 is designed specifically for the harsh conditions of Australia. Special polymers included in this product minimise viscosity decreases at high operating temperatures resulting in maximum oil pressures being maintained.
