The final number, such as 20 or 30, represents the oil's thickness at operating temperature, balancing fuel efficiency with protective film strength. It offers a practical balance between cold-weather protection and thermal stability in hot climates.
The 5W prefix signifies the oil's cold-flow properties, ensuring it moves quickly through the engine galleries on cold starts, reducing wear during the most critical moment. Synthetic formulations offer better resistance to thermal breakdown, meaning they maintain their viscosity and protective qualities longer under the high temperatures generated by the 5.
