What is the oil called for the first car maintenance?

[SanTalia]

For the first car maintenance, standard original equipment manufacturer (OEM) oil is used, without any special designation. Whether it's the first maintenance or subsequent regular maintenance, this type of oil is employed. "OEM engine oil" is essentially engine oil products manufactured by oil companies according to the requirements of automobile manufacturers. Introduction to car maintenance: 1. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. 2. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing.

I just had my first maintenance at the 4S dealership, and they used genuine OEM oil with the car logo directly printed on the packaging. The technician told me that the first maintenance is crucial for a new car, and it's essential to use oil with the right viscosity, such as 5W-30 fully synthetic oil. Why not use mineral oil? Because the engine of a new car is still in the break-in period, fully synthetic oil has better cleaning properties to flush away metal debris and provides superior high-temperature protection. Remember to ask the service staff to show you the oil container—some shops might secretly downgrade to semi-synthetic oil. Also, after the oil change, make sure to drive at high speed for about half an hour to ensure the oil film evenly coats the components.

I've seen too many cases of improper oil usage during the first maintenance at repair shops. The gap in a new car's engine is only 5 microns, so ultra-fine molecular oil must be used. The mechanic taught me to look for the GF-6A label on the oil can, which is the latest anti-oxidation standard. Pay special attention not to exceed the manual's specified oil change volume. For example, the Audi EA888 only needs 4.7 liters - adding an extra half liter can actually damage the catalytic converter. For the first 500 kilometers after the initial maintenance, avoid stomping on the accelerator to allow full grinding between the piston rings and cylinder walls. Remember to bring a magnet for the drain plug during the next maintenance - if it attracts iron filings, it indicates good break-in.
