In the current era of rapid development in the automotive industry, engine technologies are constantly innovating, and the requirements for lubricant performance are also increasing day by day. On March 31, 2025, API (American Petroleum Institute) and ILSAC (International Lubricant Standardization and Approval Committee) jointly introduced the SQ/GF - 7 engine oil standard, replacing the previous SP/GF - 6 standard.
SQ/GF - 7 Standard: Ushering in a New Era of Lubricants
The SQ/GF - 7 standard aims to meet the higher demands of modern engines for energy efficiency, environmental protection, and durability, achieving significant improvements in multiple aspects.
● Enhancing Fuel Economy: Through optimized engine and bench testing, the SQ/GF - 7 standard raises the requirements for fuel economy, helping to reduce vehicle fuel consumption and tailpipe emissions. This not only saves money for vehicle owners but also contributes to environmental protection.
● Strengthening Low - Speed Pre - Ignition (LSPI) Protection: The standard requires lubricants to provide reliable LSPI protection for the engine throughout the oil change interval, ensuring safe operation of the engine under low - speed and high - load conditions.
● Strictly Controlling Piston Deposits: The SQ/GF - 7 standard intensifies the control over piston deposits, reducing the formation of deposits in high - temperature environments, effectively extending the engine's service life, and lowering maintenance costs.
● Upgrading Wear Protection: For high - power - density engines, the new standard enhances wear protection for the timing chain, reducing abnormal wear and ensuring the stable operation of the engine's core components.
● Adding Seal Compatibility Testing: To ensure the compatibility between lubricants and engine components, the SQ/GF - 7 standard adds testing requirements for seal - compatible material types, avoiding failures caused by compatibility issues and improving the overall performance of the engine.
Kangtai's Active Response: The Path to Implementing the SQ/GF - 7 Standard
We carefully selected a variety of commonly available and newly launched gasoline - engine/hybrid passenger cars in the market, including models from American, Japanese, and domestic brands. The engines of these vehicles are all equipped with variable valve timing and gasoline direct injection technologies, enabling effective evaluation of the fuel economy and anti - wear performance of SQ/GF - 7 products under urban and highway driving conditions. By simulating comprehensive driving conditions including urban congestion, suburban roads, and highways, we comprehensively examine the lubricating performance of the products and their protective capabilities for the engine under different conditions.
1. Before the road test, a thorough inspection and maintenance of the test vehicle's engine were carried out to ensure it was in good working condition. The corresponding lubricant was added according to the product requirements, and the initial oil level and initial mileage were recorded.
2. During the road test, the vehicle was driven strictly according to the predetermined driving conditions. Professional vehicle data acquisition equipment was used to record parameters such as engine speed, load, oil temperature, and oil pressure in real - time. Meanwhile, the vehicle's tire pressure, braking system, and suspension system were regularly checked to ensure safe driving.
3. At regular intervals of mileage, engine lubricant samples were collected and sent to an analysis and evaluation center for analysis and testing. The analysis items covered the viscosity, acid value, base value, wear metal content, and pollutant content of the lubricant, so as to evaluate the performance changes of the lubricant during use.
Currently, Kangtai's road test work is progressing steadily. Multiple vehicle models have been successfully adapted. With the participation of a professional third - party road test company, the sample collection has become more scientific. The analysis and testing are conducted in cooperation with authoritative organizations such as SGS/Intertek, ensuring the reliability of the data. Through this road test, we will gain an in - depth understanding of the performance of SQ/GF - 7 products under actual driving conditions, providing a solid basis for further product optimization and market promotion.
In future research and development, we will continue to focus on product performance and are committed to providing more high - quality lubricant additive solutions for the automotive industry. The road test project is scheduled to be completed by April 30, 2025.
Let's look forward to it together.
