Sinopec gas stations provide engine oil with value-added tax invoices, which are generally genuine. The classification of gas stations and methods to distinguish genuine engine oil are as follows: Classification of Gas Stations: Sinopec gas stations are divided into two types: one is directly operated stations, where all assets and personnel belong to Sinopec. The other type is joint venture stations, where the assets are usually owned by individual proprietors, with Sinopec and private parties holding shares. Methods to Distinguish Genuine Engine Oil: Legitimate engine oil manufacturers provide various anti-counterfeiting verification methods, such as anti-counterfeiting labels, QR codes, product serial numbers, special markings, official websites, customer service hotlines, SMS verification, etc. These methods can also be used for verification.

As a seasoned driver with over a decade of experience, I often purchase engine oil at gas stations. Generally speaking, most of them are genuine products, especially at major brand stations like Shell or Mobil franchises, as they collaborate directly with manufacturers, ensuring reliable supply channels. When buying, always check if the packaging is intact and the labels are clear to avoid counterfeit products. I remember once buying oil at a small stall to save money, only to experience increased engine noise. The issue was resolved after switching to genuine oil. Now, I always insist on buying from trustworthy places for peace of mind and safety. The quality of engine oil directly affects the engine's lifespan, so being cautious is wise. You can also regularly check the viscosity of new oil using a dipstick. Protecting your car is a fundamental principle of driving—don't risk major losses for minor gains.

As someone who has researched car maintenance, I believe the engine oil at gas stations is usually genuine at authorized stations, as major stations have supplier authorization certificates and anti-counterfeiting labels. Well-known brands often have QR codes on their bottles for verification. However, be cautious with some private merchants, as there may be a risk of counterfeit products. Fake oil tends to appear cloudy and lacks clarity, feeling rough when applied. Choosing authentic engine oil for vehicle maintenance is crucial to avoid engine wear. I recommend checking brand reputation and consulting professionals before purchasing, as maintaining engine efficiency is a long-term investment.

Having driven for many years with a focus on saving money, I find that the engine oil at gas stations offers good value for money and is usually genuine. Opting for mainstream brands provides more peace of mind. For example, I've purchased it multiple times at local chain stations at reasonable prices, and my car runs smoothly. However, be cautious of extremely low-priced options as they might be adulterated. I once heard from a friend who bought cheap oil and ended up with soaring fuel consumption and costly repairs. Protecting the engine relies on good oil, and regular checks and changes are key.
