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.
Why does a car's engine get hot? Why does a car's engine get hot when it is running? A car's engine is not efficient. The engine works by converting chemical energy in the form of fuel to the mechanical energy (work) that drives the wheels and makes the car move. But only about 20 to 30 percent of the chemical energy is actually converted to mechanical energy.
