Premier SN/CF 15W/40 is the ultimate lubricant for use in the professional workshop to provide engine protection and performance. It meets the API SN and CF requirements and is suitable for most types of petrol and four stroke engines, especially those newer engines with smaller clearances. It performs superbly under the most severe and varied of operating conditions, such as high temperature motorway driving and low temperature stop-and-go city driving.
Premier SN/CF 15W/40 is a premium quality engine oil made using the latest premium technology base oils. Its high temperature performance is enhanced by the use of thermally stable base oils, oxidation inhibitors, viscosity improvers and detergents.
The level of dispersants and detergents in Premier SN/CF 15W/40 maintains the engine in a much cleaner condition under all service conditions. These special additives inhibit the formation of sludge, especially under the constant cold temperature operation of urban motoring.
Premier SN/CF 15W/40 has excellent cold crank starting properties with ideal fluidity characteristics, and provides increased engine life as the wear rates associated with this high quality engine oil are decreased by approximately 25% for cams and 2% for bearings over the previous SM grade.
Premier SN/CF 15W/40 contributes to 13% less piston deposits with improved oxidation resistance when tested under the Sequence III test methods as compared to the older SL grade engine oil.
- API SN formulation.
- Improved low temperature performance for fast oil flow at cold temperature start-up.
- Improved wear protection for longer engine component life.
- Improved oxidation resistance for protection at high temperatures.
- Improved protection from piston deposits for cleaner engines.
