What grade is SPGF6 engine oil?
2 Answers
SPGF6 is an S-grade engine oil. Engine oil grades are typically classified by viscosity and quality. The functions of engine oil are: To reduce friction and high temperatures. To minimize gas leakage and prevent external contaminants. To protect components from contact with water, air, and harmful acidic gases. To cushion the pressure rise in engine cylinders. To flush away dirt generated on component surfaces. The method for checking engine oil is: Park the vehicle on a level surface. After 10 minutes, pull out the dipstick. Hold the dipstick perpendicular to the ground to check the oil level. Signs that engine oil needs replacement are: Checking the oil viscosity - if there is no viscosity, the oil needs to be changed. The oil color turns black. Excessive black particles, metal shavings, or carbon deposits in the oil. The oil has an unusual odor.
API SP GF-6 engine oil is a combination of the latest automotive oil standards. Simply put, it refers to oil that meets the API SP grade while also complying with the ILSAC GF-6 specifications. API SP is the latest gasoline engine oil service category, primarily improving engine protection, reducing deposits and wear. GF-6 emphasizes fuel economy, lower oil consumption, and reduced emissions, making it more environmentally friendly. GF-6 is further divided into GF-6A and GF-6B categories: the former is suitable for standard viscosity oils used in most vehicles, while the latter is specifically designed for ultra-low viscosity oils like 0W-16, enhancing engine efficiency. I often see car owners using this type of oil during repairs because it is compatible with modern turbocharged and hybrid vehicles, extending engine life and maintaining performance. When selecting oil, always check the owner’s manual recommendations to ensure suitability, and avoid switching oils arbitrarily to prevent damage to engine components.
