What does SP/GF-6 mean for engine oil?
2 Answers
GF-X grade is an engine oil quality certification standard established by the International Lubricant Standardization and Approval Committee. This standard places greater emphasis on fuel economy, hence generally requiring lower viscosity. The number following GF is generally considered to correspond to national emission standards, with GF-6 commonly referred to as China VI. Function of engine oil: The engine is an indispensable part of a vehicle, and engine oil is an essential component for the engine, highlighting its crucial role in automobiles. Timely replacement of engine oil: Regarding engine oil requirements, each vehicle model has its own compatible oil specifications, which can be found in the car's user manual. If the engine oil has been used for an extended period, it is imperative for the owner to replace it promptly. Prolonged use causes the oil's viscosity to decrease, leading to a corresponding reduction in lubrication effectiveness. This diminishes the oil's ability to lubricate and protect the engine, underscoring the importance of timely replacement.
When I first encountered this topic, I found it a bit complex. SP/GF-6 engine oil refers to the latest generation of oil standards. SP is established by the American Petroleum Institute (API), specifically designed for gasoline engine protection, offering better resistance to wear and reduced carbon buildup. GF-6 is a fuel economy standard set by the international organization ILSAC, used in conjunction with SP. This combination is suitable for modern vehicles, such as those with turbochargers or start-stop systems. After using oil labeled SP/GF-6, I noticed the engine runs quieter and fuel consumption is lower. The recommended maintenance interval is to check every 5,000-7,500 miles. When changing oil, look for the certification label on the packaging and prioritize this new standard oil. Older versions like SN/GF-5 can easily cause low-speed pre-ignition issues, while upgrading can extend engine life and avoid repair troubles. As a car owner, I believe regularly using SP/GF-6 oil is a wise investment—it saves both hassle and money.
