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.

Sources say the normal range of temperature for a vehicle's engine is 195Â°F to 200Â°F, maintained with a mixture of 50% antifreeze and 50% water. When the temperature goes above 200Â°F, boiling of the coolant solution can cause overheating. An antifreeze/water 50-50 solution will boil at 225Â°F or so. Increasing the amount of antifreeze to 70% will increase the boiling temperature to 276Â°F. Engine oil also acts as a coolant and lubricant.
