What is the China VI Engine Oil Certification Standard?
2 Answers
Automobile manufacturers stipulate that China VI models equipped with particulate filters must use medium/low ash engine oil, such as ACEA-C series, GM-dexos1 series, VW50800/50900 series, etc. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and dampen vibrations in the engine. It is hailed as the "blood" of automobiles. 2. Composition: Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of base oil performance, endowing it with certain new characteristics, making them an essential part of lubricating oil.
As a veteran driver with over a decade of experience, I know that with the introduction of China VI emission standards, engine oil also needs to be upgraded. The China VI oil certifications mainly include ACEA C-series standards like C2 or C3, as well as API SP level, all designed for low ash content requirements. Specifically, the ash content must be controlled around 0.5% to 0.8%, and sulfur content below 0.3%, so that it doesn’t produce too much ash to clog the Gasoline Particulate Filter (GPF) after combustion. I once used regular oil, and the GPF got clogged, costing me thousands in repairs—it was heartbreaking. Now when changing oil, I always check for the ACEA C or API SP label on the packaging to ensure compatibility with China VI vehicles. This not only protects the engine and after-treatment system but also reduces fuel consumption and pollution, giving peace of mind about compliance. In short, don’t try to save money by using the wrong oil—it benefits both the car and the environment.
