Can engine oil brands be switched?

It is possible to switch brands, but it is important to note that the type of engine oil should not be changed. For example, if the vehicle previously used fully synthetic oil, it is essential to continue using fully synthetic oil after switching brands. This helps minimize the engine's adaptation time and ensures optimal engine performance. Engine oils are categorized into three types: the first is conventional mineral oil, the second is semi-synthetic oil, and the third is fully synthetic oil. Conventional mineral oil should be replaced every 5,000 kilometers or six months. Semi-synthetic oil should be replaced every 7,500 kilometers or nine months, and fully synthetic oil should be replaced every 10,000 kilometers or one year. When changing the engine oil, the oil filter should also be replaced simultaneously.

Changed the oil brand? I have a lot to say about this. The key to our car's oil lies in the specifications, such as the API and SAE ratings printed on the bottle. If the new car manual specifies 5W-30 full synthetic oil, then you can choose any brand as long as it matches. However, don't mix old oil from one brand with new oil from another right away, as residues might cause deposits and clog the engine. I often help friends with their cars and recommend checking the manual before each oil change—just pick a reliable brand, as most decent-quality oils are compatible. Remember, regular oil changes are more important than the brand; don't delay to avoid engine damage. Overall, switching brands flexibly is fine—it saves money and is convenient.

When it comes to switching engine oil brands, I've been driving a taxi on the streets for over 20 years and have tried all kinds of brands—it's really no big deal. The key is choosing the right viscosity. For example, if the car specifies 5W-40, don't randomly switch to 0W-30. I've used big names like Shell and Mobil, and also tried some smaller brands—as long as they're properly certified, there's nothing to worry about. In real-world driving, I've never encountered any issues, and it even saves some money. The only thing to watch out for is not switching too frequently to avoid the oil system getting unsettled. When changing the oil, take the chance to check the filter to ensure everything runs smoothly. At the end of the day, engine oil is there to protect the engine—the brand isn't a dealbreaker. As long as it meets the standards, feel free to switch.

When I first bought my car last year, I was also concerned about the brand of engine oil. Actually, it's perfectly fine to switch between brands as long as the label matches your car's requirements. Nowadays, many online stores offer affordable and convenient engine oil options. I've purchased different brands of semi-synthetic oil from JD.com and had no issues. Just remember to check the SAE rating on the bottle before each oil change—don't just guess. After switching brands, my car still runs smoothly with no noticeable difference. However, don't go for extremely low-quality oil just to save money, as it might increase fuel consumption. Regular maintenance is what truly matters—don't get too hung up on brands.
