What is SP engine oil?
1 Answers
SP engine oil introduces two new test items: low-viscosity oil (5W30, 0W20) testing and timing chain wear testing. The main functions of SP oil are as follows: 1. During high-speed engine operation, the timing chain links and pins are prone to wear, causing gradual chain elongation and potential failures. 2. With a density of approximately 0.91×10³, engine oil provides lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. 3. Base oil is the primary component of lubricants, determining their fundamental properties, while additives compensate for and enhance the performance of base oils, imparting new characteristics, making them an essential part of lubricants.
