What is the ILSAC motor oil standard?

ILSAC motor oil standard is an organization that certifies the specifications of lubricant products. Introduction to ILSAC specifications: ILSAC has established gasoline engine oil specifications including GF-1, GF-2, GF-3, GF-4, GF-5, as well as the GF-6 specification introduced according to the latest fuel economy regulations. Introduction to ILSAC: International Lubricant Standardization and Approval Committee; Similar to ACEA and API, it is also an organization that certifies lubricant product specifications. It was jointly established by the American Automobile Manufacturers Association (AAMA) and the Japan Automobile Manufacturers Association (JAMA), with its certifications issued by the American Petroleum Institute (API).
I think the ILSAC oil standard is crucial for car maintenance. I remember when I was younger and drove a modified car, I always used regular oil. Later, a friend introduced me to the ILSAC GF-6 standard, saying it was developed jointly by major automakers in the U.S. and Japan, specifically designed for fuel economy and engine protection. It has that starburst certification logo, ensuring the oil reduces friction and improves engine efficiency—like GF-6A and GF-6B, which are tailored for different vehicle types. Now, I always choose this when changing oil, and I feel like fuel consumption has decreased a bit, and the car runs smoother. Using the wrong oil can cause faster engine wear and expensive repairs. So, I suggest fellow car owners check for the ILSAC logo on the bottle when inspecting their oil and avoid cheap, off-brand products.
As an ordinary car owner with kids at home, I pay special attention to the reliability of automotive lubricants. The ILSAC standard is an internationally established regulation primarily aimed at making engine oil more fuel-efficient and protective for engines. It has grades like GF-5 or GF-6. Every time I go for maintenance, I ask the mechanic to use oil with this certification because it has passed fuel economy tests, allowing me to drive a bit farther per liter of fuel. It also reduces emissions, making it environmentally friendly. If the oil doesn't meet the standard, problems might not be visible in the short term, but over time, it can damage the engine, leading to costly and time-consuming repairs. My experience tells me that buying a certified product saves money and hassle in the long run, without compromising family safety.
