What is the National VI Engine Oil Certification Standard?

[LenaFitz]

Automobile manufacturers stipulate that National VI models equipped with particulate filters must use medium/low ash engine oil, such as the ACEA-C series, GM-dexos1 series, VW50800/50900 series, etc. The relevant information about engine oil is as follows: Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is often referred to as the 'blood' of a car. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives compensate for and improve the shortcomings of the base oil, imparting new characteristics. Additives are an essential part of lubricating oil.

The China VI engine oil certification standard is primarily designed to meet the stringent requirements of China VI emission vehicles, demanding oils with low ash and low sulfur content to reduce particulate emissions and protect after-treatment systems like GPF particulate filters. As someone who regularly maintains vehicles, I've noticed it emphasizes that oils must comply with API service levels such as SP or CK-4, or ACEA classifications like C5/C6, which help prevent clogging and maintain engine longevity. Conventional oils with high ash content can increase maintenance costs and emission pollution over time, so I recommend car owners carefully check the certification labels on bottles to ensure compatibility. Regular replacement of such oils can also save fuel and extend vehicle lifespan, especially for new cars—don’t overlook this to save hassle and effort.

I often deal with car maintenance. The China VI oil standard, simply put, requires cleaner oil with lower ash and sulfur content compared to older standards. In terms of certifications, common grades include API CK-4 or SP, and ACEA C5, which aim to protect the emission system from clogging and reduce malfunctions. If you drive a China VI vehicle, using the right oil can save you a lot on repair costs. Just pay attention to the product certification information when choosing oil. Avoid using low-quality oil, as it can accelerate part wear. Proper maintenance also leads to more environmentally friendly emissions and a smoother, hassle-free driving experience.

As an environmental advocate, I believe the core of China VI oil certification is to promote low-SAPS (low sulfur, ash) oils, such as C5/C6 standards, to reduce exhaust pollution. These certifications are managed by organizations like API or ACEA, ensuring the oil does not harm emission control equipment. Using it not only benefits the environment but also saves on maintenance, contributing overall to air quality control.

I've been driving a lot in recent years, and the China VI engine oil standards are more stringent, requiring low-ash formulations that are compatible with emission systems. Certifications include API SP, CK-4, or specific OEM brand levels to prevent GPF clogging. When selecting oil, check the label certifications and avoid using non-standard oils just to save money. Regular oil changes can prevent performance degradation. Maintenance for China VI vehicles is more critical, and using the right oil ensures a quieter and more efficient engine.

The China VI engine oil certification is designed based on emission regulations, focusing on low-ash oils such as C5/C6 grades, which protect the aftertreatment system and reduce clogging issues. The certification involves API or ACEA standards, and selecting engine oil should match the recommendations in the vehicle's manual. Using such products during maintenance enhances vehicle power and reduces emissions. Don't overlook the details—incorrect oil can lead to frequent malfunctions. Using certified oil for maintenance ensures peace of mind.
