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

[DeTessa]

For the first free maintenance at a car 4S dealership, original equipment manufacturer (OEM) engine oil is typically used. In fact, OEM engine oil is produced by oil manufacturers according to the requirements of the car manufacturers. The first maintenance period for a new car is usually determined by either the mileage or the specified time interval, whichever comes first. Therefore, if the time interval is reached but the mileage is insufficient, the first maintenance should still be performed. Otherwise, the 4S dealership may claim that the standard has not been met, resulting in the information not being recorded in the nationwide warranty system, leading to the loss of warranty coverage. Precautions for the first car maintenance: In addition to changing the engine oil and oil filter, the first maintenance includes a comprehensive inspection and diagnosis of the vehicle's condition and usage. Typically, the first maintenance items are free of charge. If the technician recommends services not included in the first maintenance, the car owner should inquire whether there will be additional charges before deciding whether to proceed. As long as the new car undergoes its first maintenance at the 4S dealership within the specified period, it will still be eligible for the three-guarantee service even if subsequent maintenance is performed elsewhere. However, if the new car owner fails to have the first maintenance performed at the designated 4S dealership or the manufacturer's authorized service station within the specified mileage, any issues that arise with the car, even within the warranty period, may require the owner to pay certain repair costs.
