Is the "blood" of your beloved car up to standard?

On the late-night highway, the oil warning light suddenly lit up on a BMW. Ms. Li's hands gripping the steering wheel were sweating coldly. There were still 30 kilometers to the nearest service area... Such thrilling moments often stem from the blind spots in the understanding of the "blood" of cars - lubricants. Today, we will unveil the little-known quality code of the Changning Imported Lubricant Agency industry.

The maintenance bill of Mr. Zhang's Mercedes-Benz 4S store shows that the price of the original factory-designated lubricant is three times that of similar products on the market. This is not brand premium, but imported lubricants have three core advantages:

• Molecular Stability: The viscosity attenuation rate of BASF base oil from Germany is less than 5% at a high temperature of 150℃.
• Cleaning Efficiency: The additives from Lubrizol in the US can reduce the formation of carbon deposits by 90%.
• Environmental Protection Standards: The lubricant certified by ACEA C5 can double the lifespan of the three-way catalytic converter.

Through the market research of Zhongshitong, we found that consumers often fall into the following cognitive traps:

• Mistakenly equating the API SN level with the quality standard (actually it needs to be combined with the ILSAC GF-6 certification).
• Believing that high-viscosity oil provides better protection (modern turbocharged engines actually need 0W-20 low-viscosity oil more).
• Ignoring the exclusive certification systems of automobile manufacturers such as BMW LL-04.

In the face of 30% of counterfeit imported lubricants on the market, the technical director of Zhongshitong suggests:

• Scan the QR code on the barrel body to trace the customs clearance document number.
• Check whether the anti-counterfeiting teeth on the barrel lid are intact (the genuine product has 12 consecutive saw teeth).
• Freezing test: The genuine product remains amber and transparent at -30℃.
• Request the electronic version of the MSDS (Material Safety Data Sheet).

With the full implementation of the China VI B standard, the lubricant industry is facing a technological reshuffle:

• The low-ash formula (SAPS ≤ 0.5%) will become a mandatory requirement.
• The market share of bio-based lubricants is expected to increase by 200%.
• Blockchain technology will enable the whole-process traceability from the refinery to the engine.
