[Penelope]

As long as they are genuine products, engine oils from 4S stores and external sources are the same regardless of where they are purchased. Below are explanations of the differences between 4S store engine oil and external engine oil, along with some precautions: Differences between 4S store engine oil and external engine oil: Engine oil purchased externally is more likely to be counterfeit or of unverified quality, whereas 4S stores operate under the manufacturer's standard operating model, ensuring that the engine oil is generally genuine. However, due to the higher labor costs for maintenance, budget-conscious car owners often prefer external repair stations for servicing. Precautions when changing engine oil: Therefore, consumers should not worry excessively about the quality of 4S store engine oil, as genuine engine oils are of the same quality. It is important to remember to change the oil filter when replacing the engine oil and to inspect the vehicle's condition during maintenance, such as checking for any undercarriage damage or oil leaks.
