In petrol (gasoline) engines, the top piston ring can expose the motor oil to temperatures of 160 Â°C (320 Â°F). In diesel engines the top ring can expose the oil to temperatures over 315 Â°C (600 Â°F). Motor oils with higher viscosity indices thin less at these higher temperatures.
Car Engine Oil Basics. The primary function of automotive engine oil is to provide lubrication to the metal surfaces inside an engine. With proper lubrication the components will not rub against each other as frequently and wearing out due to friction can be reduced.
