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.
Most commonly, the adiabatic combustion temperatures for coals are around 2,200 Â°C (3,992 Â°F) (for inlet air and fuel at ambient temperatures and for Î» = 1.0 {\displaystyle \lambda =1.0} ), around 2,150 Â°C (3,902 Â°F) for oil and 2,000 Â°C (3,632 Â°F) for natural gas.
