How to Identify National VI Standard in Engine Oil?
2 Answers
National VI emission standard is marked with the Roman numeral "Ⅵ". When purchasing a new car, the dealer will provide an acceptance form, which must indicate the vehicle model, color, emission standard, engine number, and chassis number. For older vehicles, the complete vehicle model can be checked on an environmentally friendly website. Below is an introduction to National VI: 1. Introduction: The National VI standard for motor vehicle pollutant emissions, abbreviated as "National VI", is a standard formulated by the national authorities to prevent environmental pollution caused by the use of compression-ignition and gas-fired fuels in vehicles, protect the ecological environment, and safeguard human health. 2. Purpose: The fundamental purpose of switching to "National VI" vehicles is environmental protection. According to strict environmental regulations, drivers will eventually face the most stringent emission standards in history, which are reflected not only in vehicle exhaust emissions, engine displacement, and vehicle drive forms but also at the strategic level of sustainable development. This indicates that large-displacement engines will soon become history.
When I previously drove a China VI emission standard vehicle, I was often troubled by engine oil compatibility issues. To determine if the oil meets China VI standards, the most straightforward method is to check the certification label on the oil packaging bottle. China VI vehicles typically require low-ash engine oil to avoid clogging the gasoline particulate filter (GPF), so look for ACEA C-standard series like C2, C3, or API SP grade. These labels are usually clearly printed on the side or back of the bottle. Don't just focus on the brand—major brands like Mobil and Shell offer different specifications. Additionally, checking the owner's manual is the most reliable approach, as it will specify the recommended oil type and grade. Some websites or apps also allow you to check oil certification information by entering the brand and model. Using the wrong oil may lead to increased fuel consumption and emission issues, so I always double-check before each oil change. In short, paying attention to these details when purchasing in-store or online can save you a lot of hassle.
