Is Engine Oil Divided into Winter and Summer?
1 Answers
Engine oil is divided into winter and summer. Generally, winter engine oil has lower viscosity, while summer engine oil has higher viscosity. There is also all-season engine oil with moderate viscosity. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil's performance, giving it certain new properties, making them an important part of lubricating oil. The method for changing engine oil is: 1. Use a jack to lift the vehicle, locate the drain bolt, and unscrew it to drain the oil; 2. After removing the oil filter, place a container beneath it; 3. Replace with a new oil filter and add new engine oil.
