Can Different Engine Oils Be Mixed?
1 Answers
Different engine oils should not be mixed. Engine oil is used to maintain the operation of the engine, cooling and lubricating its components, and is also a crucial means to ensure the normal operation of various moving parts in the vehicle, reduce operational resistance, lower temperature, and minimize wear. Improper use of engine oil can not only shorten the engine's lifespan but may even lead to engine failure. The type of oil a car should use is related to the engine's compression ratio, and the oil grade should be chosen within the range of the engine's compression ratio. The gasoline grade has little to do with the quality of the gasoline itself; the gasoline grade represents its anti-knock properties, with a higher grade indicating better anti-knock performance. The anti-knock property is determined by the amount of octane added to the gasoline. The fuel grade refers to the octane number and is unrelated to the amount of impurities in the gasoline.
