Premier 15W/50 SM is the ultimate in protection and performance designed for the workshop or home service. This premium quality engine oil is made using the latest synthetic technology base oils. It meets and exceeds the API SM/CF specifications and is suitable for most types of petrol and four-stroke diesel engines including those engines with small clearances and those operating under the most severe and varied operating conditions, such as high-temperature motorway driving or low temperature stop-and-go driving.
Premier 15W/50 SM is also ideal for cold starting situations because of excellent low-temperature fluidity characteristics, and it also provides increased engine life since the wear rates associated with older quality engine oils is decreased by up to 20% for cams and 13% for bearings.
Premier 15W/50 SM contributes up to 21% less oxidation and more protection from piston deposits compared to older engine oils when tested under the Sequence IIIE test technique. The level of dispersant and detergent additives in Premier 15W/50 SM contributes to the maintenance of the cleanliness of the engine under all service conditions. The special additives inhibit the formation of sludge especially under the constant cold temperature operation of urban motoring.
The high-temperature performance Premier 15W/50 SM is enhanced by the selection of thermally stable base oils, oxidation inhibitors, viscosity improvers and detergents.
