When we talk about SP in engine oil, we are referring to the grade standard of the engine oil, which represents the quality and performance of the engine oil. SP is one of the engine oil grade standards established by API (American Petroleum Institute) and is currently one of the most popular engine oil grades.
In the API grade standard, SP represents the quality and performance of gasoline engine oil and is the highest grade of engine oil. It consists of two parts: S and P.
The S part represents the oil’s fuel economy, low-emissions performance and durability. These properties are important indicators of modern engine oils because they directly affect the engine’s fuel efficiency and emission levels.
The P part represents the high temperature resistance and lubrication properties of the engine oil. It ensures that the engine oil remains stable when the engine is running at high temperatures and can provide adequate lubrication and protection for the engine.
Therefore, SP in engine oil refers to gasoline engine oil that meets the highest level requirements in API grade standards. It has excellent fuel economy, low emission performance, durability and high temperature resistance, and can provide comprehensive protection and stable operation of the engine.
The importance of SP in engine oil is self-evident. In modern engines, the role of engine oil is not only lubrication and cleaning, but also important tasks such as reducing fuel consumption, reducing emissions, and extending engine life. Therefore, using engine oil that meets SP standards can ensure the best running condition of the engine, improve fuel efficiency, reduce emissions, and extend the service life of the engine.
How to choose the right SP engine oil? First, we need to consider the price and quality of the engine oil. Generally speaking, the price of SP engine oil will be higher than other grades of engine oil, but its quality and performance are correspondingly higher. Secondly, we need to consider the brand of engine oil and applicable models. Different brands and models require different types of SP engine oil. Therefore, when choosing engine oil, we need to understand our own car model and needs and choose the SP engine oil that suits us.
In short, SP in engine oil refers to gasoline engine oil that meets the highest level requirements in API grade standards. It has excellent fuel economy, low emission performance, durability and high temperature resistance. In modern engines, using engine oil that meets SP standards can ensure optimal engine operation, improve fuel efficiency, reduce emissions, and extend the service life of the engine. When choosing SP engine oil, we need to consider the price and quality of the engine oil, as well as the brand and applicable models, to ensure that we choose the SP engine oil that is most suitable for our vehicle.
