What kind of engine oil is used for the first maintenance at a 4S shop?

Most first maintenance services use mineral oil or semi-synthetic oil provided for free during the initial service. Precautions for the first car maintenance: 1. Inquire about costs for items not covered in the first maintenance: Besides changing the engine oil and oil filter, the first maintenance includes a comprehensive inspection and diagnosis of the vehicle's condition and usage. Typically, these services are free. If the technician suggests services not included in the first maintenance, the owner must ask whether there will be charges before deciding to proceed. 2. Maintenance must be done at the designated 4S shop: As long as the first maintenance is performed at the 4S shop within the specified period, the warranty will remain valid even if subsequent maintenance is done elsewhere. However, if the owner fails to take the new car to the designated 4S shop or an authorized service station for the first maintenance within the specified mileage, any issues that arise, even within the warranty period, may require the owner to bear certain repair costs.
