What Vehicles Are Suitable for SL Grade Engine Oil?
1 Answers
Engine oil SL refers to the grade of the engine oil, and its suitability for specific vehicle models depends on the owner's personal choice. Engine oil SP represents the quality grade of the oil. SG, SJ, SL, SM, and the subsequent SP are all grades for gasoline engine oils, with SP being the highest grade currently available for gasoline engines. The higher the grade of the engine oil, the better its various technical indicators, which can significantly extend the engine's lifespan, prolong oil change intervals and maintenance cycles, and reduce vehicle maintenance costs. The difference between engine oil SN and SP lies in the thickness of the oil at a certain temperature, or its viscosity (phosphorus content). Below is a detailed introduction: 1. SN engine oil has a relatively lower phosphorus content; moreover, when comparing the viscosity of SN and SP oils, SP has a slightly higher viscosity value. 2. This indicates that SP's oil film is stronger than SN's, providing better protective performance. Additionally, SP offers stable improvements over SN in terms of noise reduction, fuel consumption, and acceleration performance.
