1 Answers
API-SP is an SP-grade engine oil. Here is an introduction to engine oil: Methods for selecting engine oil: Naturally aspirated engines have relatively modest requirements for oil quality and can use mineral oil or semi-synthetic oil. If the owner's budget allows, fully synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more tightly constructed engine and operate under harsher conditions, requiring higher-performance engine oil with better fluidity. It is best to use fully synthetic oil. Functions of engine oil: Engine oil is something every car owner comes into contact with during vehicle use. Engine oil is referred to as the lifeblood of the engine. Without engine oil, the engine cannot operate normally. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat.
