Does engine oil exceeding six months have a significant impact?
1 Answers
The impact is not significant, but in principle, it should not exceed one year. The specific duration should be based on the maintenance manual. Below is some information about engine oil: 1. Composition: Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives are an important part of lubricating oil. 2. Types of engine oil: The winter oil grades under the SAE lubricating oil viscosity classification are 0W, 5W, 10W, 15W, etc. The symbol W stands for winter, and the smaller the number before W, the lower the low-temperature viscosity and the lower the applicable minimum temperature. The summer oil grades under the SAE lubricating oil viscosity classification are 20, 30, 40, 50, with larger numbers indicating higher viscosity and higher applicable maximum temperatures.
