Fleetmaster CJ-4 Semi Synthetic 10W/40 is formulated using the latest technology mineral and synthetic base oils for use in heavy duty diesel engines operating in the harsh Australia conditions. The very high dispersant, anti-wear formulation exceeds the requirements of API CJ-4. This lubricant is specifically designed to meet the requirements of the latest US07 emission standards for engines with exhaust treatment systems especially DPF (diesel particulate filters) and cooled EGR (exhaust gas recirculation) using low sulphur fuels.
Fleetmaster Semi Syn CJ-4 10W/40 exceeds many international specifications for top performance and long service life in four stroke turbo-charged and normally aspirated diesel engines. It assists in reducing soot thickening in the latest US low emission engines.
Fleetmaster Semi Syn CJ-4 10W/40 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 Semi Syn CJ-4 10W/40 minimises the formation of damaging deposits in ring grooves and land areas, particularly the quench top ring belt areas of ‘tight piston’ engines.
The special balance of over-based alkaline reserve additives (TBN components) in Fleetmaster Semi Syn CJ-4 10W/40 effectively neutralises acidic combustion by-products caused by the sulphur content in fuel (especially diesel fuel). This helps reduce the corrosion of critical engine components and the otherwise catastrophic effects these by-products have on oil.
