What is 5W-30 and 5W-40?

5W-30 and 5W-40 refer to the viscosity grades of engine oil. The 'W' stands for winter, indicating the oil's performance in cold temperatures. The numbers before the 'W' indicate the oil's viscosity at low temperatures, while the number after the 'W' indicates its viscosity at high temperatures.
