Can I Change the Brand of Engine Oil for My Car?
2 Answers
It is not recommended to frequently change the brand of engine oil for your car, but it is not absolutely forbidden. As long as the replacement oil is from a legitimate source and the specifications are correct and qualified, it will not harm the car or its engine. Engine oils of the same specification have identical performance. Always purchase engine oil through official channels and avoid using low-quality or unknown-brand oils, as poor-quality oil can affect the engine's lifespan. Precautions when changing to another brand of engine oil: 1. Ensure the old oil is thoroughly cleaned. First, drain the old oil as much as possible, then add a small amount of new oil or a dedicated engine cleaning oil for flushing. 2. For older cars with significant sludge buildup, it is advisable to disassemble the engine to clean the sludge before changing the oil. This not only ensures better lubrication but also helps restore engine performance. 3. After maintenance, perform another inspection.
I've personally tried switching engine oil brands several times without major issues. But you need to be cautious - make sure the new oil specifications match your vehicle's requirements, such as viscosity and API rating aligning with factory recommendations. When driving an older car, I switched from mineral to synthetic oil while keeping the same 5W-30 viscosity, resulting in stable performance and better lubrication. Different brands may have significantly varied additive formulations - mixing oils might be okay for short-term use, but for long-term, I recommend completely draining the old oil before adding new oil to avoid compatibility risks. After changing, listen for abnormal engine sounds and check oil pressure to ensure no strange noises or leaks. Additionally, synthetic oils generally offer better quality and compatibility. If you frequently drive in city traffic, choosing a reputable synthetic brand will provide better durability. In summary, brand switching is possible, but take it step by step - don't make abrupt changes.
