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.
For example; if you have a SAE 10 motor oil it will flow like a 10W at the colder temperature. But at 210 degrees it will be a SAE 10 giving us a 10W-10 or SAE 10 viscosity rating. Obviously this is good at cold start up, but terrible at engine operating temperature especially in warmer climates.he numbers without the W are all tested at 210Â° F or 100Â° C which is considered an approximation of engine operating temperature. In other words, a SAE 30 motor oil is the same viscosity as a 10w-30 or 5W-30 at 210Â° (100Â° C).
