In the Chinese market, there are numerous engine oil and motor oil brands, including well-known international names and domestic manufacturers such as Mobil, Castrol, Shell, Great Wall, Lopal, and OEM motor oils from BYD and others.
However, due to the size of the market, counterfeit engine oils and motor oils have become a major concern for both car owners and repair shops.
Fake oils not only reduce lubrication effectiveness but can also cause engine wear, motor overheating, and shortened component lifespan, posing serious risks.
Therefore, learning how to distinguish genuine oil from counterfeit products is essential — and finding a reliable supplier is the most important step.
Many types of engine-oil bottles exist on the market, but not all of them are genuine.
Today, a large number of counterfeit oils imitate the appearance of well-known brands.
From the bottle color, cap design, printing quality, to the outer packaging box — counterfeit products can look almost identical to the real ones.
However, no matter how similar the bottle looks, if the oil inside is fake, it will cause long-term damage to the vehicle.
❗ Why is fake oil so common?
• Counterfeit factories can produce “fake bottles” at extremely low cost
• Mass-producing fake bottles is cheaper than collecting used genuine bottles
• Therefore, counterfeiters will not spend money on real bottles or authentic anti-counterfeit coding systems
This means:
Even if a bottle looks exactly like the real one, it may still contain low-quality or harmful oil.
How to Identify Genuine Engine Oil / Motor Oil
Most Chinese engine-oil and motor-oil brands now use anti-counterfeiting systems. Common verification methods include:
1️⃣ QR Code Scan (initial check)
Scanning the QR anti-counterfeit code on the bottle lets you view basic verification information.
👉 However, note: fake QR codes are cheap and easy to reproduce, so this cannot be the only basis for authenticity.
2️⃣ Phone Verification (the most accurate method)
Almost all big brands have an official phone-verification system.
Provide the bottle’s code to customer service — this gives the most accurate and authoritative authenticity result.
This is currently the most reliable method available.
3️⃣ The code must match the query result
A genuine bottle’s anti-counterfeit code and batch code must:
✔ Match the brand’s official query result
✔ Correspond to the correct model and product line
✔ Not show duplicate verification records
Possible fake-oil signs:
• Code not found
• Query result does not match
• Code and oil model do not match
• Same code checked multiple times
These are all common indicators of counterfeit oil.
4️⃣ The biggest flaw of fake bottles: codes never fully match
Counterfeit factories will not:
• Spend money to recover genuine used bottles
• Develop authentic brand-level coding systems
• Synchronize batch codes with official databases
This means:
Checking the code is one of the fastest and most reliable ways to identify fake oil.
