Why Can't the QR Code on Castrol Engine Oil Be Scanned?
3 Answers
If the mobile app's database doesn't have it, the QR code won't scan. Many things can't be scanned with a phone. You can check on the China Article Coding Center website. If it's not there, it might be counterfeit. Differences in packaging: Genuine Castrol engine oil packaging has vertical line textures on the barrel, resembling fine lines, with distinct edges at the bottom transition area. Counterfeit oil packaging feels noticeably granular, with smoother transitions at the bottom. Differences in bottle neck craftsmanship: Genuine products have finely crafted bottle necks with no flaws, and clear joints are visible. Counterfeit oil has rough craftsmanship, with no visible sealing lines but visible untreated residual materials. Differences in bottle caps: Genuine Castrol oil has a foil seal at the cap with clear text on the foil, tight sealing, and a protective pad inside the cap. Counterfeit oil may have foil but lacks text, has weak adhesion, and no protective measures inside the cap.
A few days ago, I bought a bottle of Castrol engine oil, but the QR code wouldn't scan after multiple attempts—possibly due to a dirty label or an uncleaned phone lens. When oil stains or dust block the code, scanning becomes ineffective. I found that gently wiping it with a cloth before scanning helped significantly. Strong or weak lighting can also affect focus, so try realigning in a shaded area. Outdated apps or incomplete permissions may cause failures too; updating WeChat's scan feature worked for me. Unstable networks can slow QR code connections to backend servers—switching to mobile data might help. The worst-case scenario is fake products with invalid QR codes. I always buy from authorized stores to prevent engine damage from counterfeit oil. Safety first: if issues arise, contact Castrol's customer service immediately to verify authenticity.
Failed scans of Castrol QR codes are quite common. I think the QR code itself might be printed blurry or have creases, making it hard to see and scan. Improper phone settings, such as having auto-focus turned off, can reduce the camera's recognition ability—I solved this by adjusting the camera mode. Environmental lighting can also be an issue; strong reflections may obscure the label, so trying from different angles multiple times helps. Poor app compatibility or system maintenance in the background can temporarily prevent scanning—I’ve experienced this and found it worked fine when trying again another day. Counterfeit products often have invalid QR codes, so it’s important to check the packaging’s anti-counterfeiting marks and verify information on the official website. As someone who regularly maintains my car, using genuine oil is crucial for extending the vehicle’s lifespan.
