Suitable Viscosity
The viscosity of oil should not change with rise in temperature
The viscosity of oil should not change with rise in temperature
It ensures the adherence to the bearings and spread over the surface. This property makes oil smooth and very important in boundary lubrication.
The lubricant must have high strength to avoid metal contact and seizure under heavy loads.
The lubricant should not react with surfaces and any deposit in the cylinder.
It should be low to allow the flow of lubricant at low temperature to the oil pump.
The oil should act as cleaning agent inside the engine and should carry any deposits with it.
