On July 1, 2026, the new national standard GB 11121-2025 for gasoline engine oil will be officially implemented, fully replacing the old standard that has been in use for 19 years. This update aims to address the rapid development of engine technology in recent years and provide more precise protection for the new generation of engines.
What do car owners need to pay attention to?
What has the new national standard updated?
The biggest change in the new national standard is the introduction of multiple high-performance specification levels such as SP, GF-6A, GF-6B, etc., to meet the demanding requirements of current mainstream turbocharged direct injection (GDI) engines. At the same time, it decisively removed outdated levels such as SE and GF-1, eliminating outdated performance standards. After this adjustment, the total number of gasoline engine oil quality grades under the national standard has been expanded to 14, forming a clearer and more modern gradient.
The implementation of GB 11121-2025 is an important symbol of China's lubricant standards aligning with international advanced levels. For car owners, this means they can enjoy oil products that are more compatible with modern engine technology, provide more comprehensive protection, and are more energy-efficient and environmentally friendly. Just remember the three key steps of "checking grade, selecting viscosity, and recognizing new standards" to make the wisest choice for your car.
