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.
RE: Temperature of combustion SI engine. If understand the flame temperature diagram correctly, the temperature difference with oil is roughly 2200 C (2200 K) (starting at 298 K). So, if one ends up with a temperature of 600 C at TDC just before ignition, the temperature should reach 2800 C after ignition. RE: Temperature of combustion SI engine. EGT at the exhaust port on my 2.0L - FI - 4cyl @ 28psi MAP is between 1200-1600F. There is going to be a big difference between combustion adn actual gas temp.
