How Much Engine Oil Should Be Added During Regular Car Maintenance?

Generally, about 4 liters of engine oil is added during regular car maintenance. Engine oil is the lubricant for the engine. To ensure the car's performance, the engine oil needs to be replaced periodically, and the replacement interval depends on the oil's effective lifespan. 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. Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life.
I maintain my car quite often and have noticed that the amount of engine oil required actually varies by vehicle. For most models, adding 4 to 6 liters during an oil change is usually sufficient, depending on your engine size and type. Small-displacement cars may only need 4 liters, while larger SUVs often require around 6 liters. Remember to completely drain the old oil before refilling, as residual oil can affect the performance of the new oil. I recommend making it a habit to check the owner’s manual first to confirm the exact amount—it’s all clearly specified there, so don’t cut corners. After adding the oil, don’t rush to drive. Start the engine, let it run for a few minutes, then turn it off and check the dipstick. The oil level should be between the min and max marks to be considered correct. Incomplete draining or overfilling can lead to leaks and engine contamination, while insufficient oil can cause component wear and shorten engine life. During regular maintenance, also check for aging seals to avoid major repair issues down the line.
