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.
Regular 5W-20 pours at - 35 below 0. Cold starts (Summer and Winter) is where 80% of all engine wear occurs. It's to the motors advantage to allow the oil pump to force oil upstairs inside the oil galleries quickly. corresponds to the weight of the oil at operating temperature. 20 (or 30) corresponds to the weight of the oil when cold. Viscosity of oil reduces as the temperature increases. Think butter. So 5W20 and 5W30 are the same when the engine has reached its operating maximum temperature.
