What Type of Engine Oil Should Be Added in Northern Winters?
1 Answers
In northern winters, SAE 0W engine oil should be added, such as 10W40, 5W40, or 0W40 models. The SAE viscosity classifications for winter engine oils are: 0W, 5W, 10W, 15W, 20W, and 25W. The symbol 'W' stands for winter, and the smaller the number before 'W,' the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. Northern winters are relatively cold, so it is advisable to choose engine oil with slightly lower viscosity. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of lubricating oil, determining its basic properties, while additives compensate for and improve any deficiencies in the base oil's performance, making them an essential part of lubricating oil.
