Should EA888 use 5W30 or 5W40?
1 Answers
EA888 uses 5W40 grade engine oil. Compared to 5W30 and 5W40, they have the same low-temperature flow performance, but different high-temperature performance. 5W40 has higher viscosity and better high-temperature protection performance. From the HTHS index perspective, Volkswagen requires this indicator to be greater than 3.5, and 5W40 engine oil's HTHS value can meet this requirement. Below is relevant information about engine oil: Function of engine oil: Engine oil can lubricate and reduce wear, assist in cooling, seal and prevent leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is known as the "blood" of the car. Choosing the right engine oil and changing it regularly can maintain the engine in good condition and extend its service life. Choosing engine oil: When selecting engine oil, it's not about choosing the most expensive one, but rather selecting the appropriate oil based on the characteristics of the car's engine and usual driving habits. It can be categorized by the oil used in winter and the oil used in summer. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to high temperatures, there's no need to choose engine oil with a better low-temperature viscosity grade.
