[LeKinsley]

0W40 engine oil can be used in summer. Here are the specific details about the engine oil: 1. Usage range and advantages of 0W40 engine oil: Whether in low or high temperatures, 0W40 engine oil has a higher viscosity, which provides excellent protection for the engine. Therefore, 0W40 engine oil is suitable for all seasons. The number 40 after the 'W' indicates the oil viscosity at 100°C. 2. Engine oil can be classified by viscosity grade or by quality grade: The best quality is fully synthetic oil, followed by semi-synthetic oil, and lastly mineral oil. Additionally, the name of the engine oil variant will indicate its viscosity grade at both high and low temperatures. The number before the 'W' represents the oil's viscosity at low temperatures, with a smaller number indicating higher viscosity. The number after the 'W' refers to the viscosity index at high temperatures, where a larger number indicates higher viscosity and better protective effects of the oil.
