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.
Low Motor Oil Levels. A car with a low oil level may overheat because oil carries heat away from the engine. Running low on oil is harmful in other ways too; for example, oil acts as a lubricant, and no oil can lead to excessive wear on some parts because theyâre not adequately lubricated.
