Which engine oil is more suitable for cars in winter?
2 Answers
In winter, engine oils with grades such as 0W, 5W, 10W, 15W, 20W, and 25W are more suitable for cars. The symbol 'W' stands for winter, and the smaller the number before 'W', the lower the viscosity at low temperatures, the better the low-temperature fluidity, and the lower the minimum applicable temperature. The larger the number after 'W', the higher the viscosity, ensuring more stable performance at high temperatures. Below is more information about engine oil: 1. Engine oil serves to lubricate and reduce wear, assist in cooling, seal and prevent leaks, prevent rust and corrosion, and provide shock absorption for the engine. 2. Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil, endowing it with certain new properties, making them an important part of lubricating oil.
I'm someone who enjoys delving into car maintenance. In winter when temperatures drop, oil fluidity is crucial. It's advisable to choose lower viscosity oils like 5W-30 or 0W-20—the smaller the first number, the better the low-temperature performance. These oils can quickly pump to all parts of the engine during cold starts, reducing wear and preventing hard starts that might jam components. Synthetic oil is more suitable for cold seasons as it's more stable than mineral oil and less prone to thickening. Don't overlook your owner's manual—it will specify the recommended oil type. Remember to check the oil level and condition each season. If it's aged or discolored, replace it promptly to avoid engine failure. A good winter oil change can keep your engine running smoothly throughout the season.
