What does the free maintenance of 4s shop include?
Free maintenance in most 4s shops includes free oil change and some necessary vehicle inspection.
Engine oil is the blood of the engine. Without engine oil, the engine can't run normally.
Engine oil has many functions in the engine, not only for lubricating the engine, but also for cleaning, sealing, buffering, rust prevention and heat dissipation.
When the engine is running, the engine oil will form an oil film on the surfaces of the components in the engine, thus avoiding the direct contact between the components in the engine and causing friction.
If the engine uses engine oil for a long time, its performance will decrease, which will aggravate the wear of the engine.
So be sure to change the oil on time.
Replace the oil filter at the same time every time the oil is changed.
The oil filter element is an important part of the engine, and its function is to filter the oil.
If there is no oil filter, the oil will become dirty after a period of use, which will also affect the normal lubrication of the oil.
When you buy the oil filter, you must choose the genuine products of big brands. Don't underestimate this part, because it is closely related to the oil change cycle of the car.
For cars, when you use the car, you must maintain it on time, because daily maintenance is very important.
Only timely maintenance can keep the car in good condition, and genuine accessories and engine oil must be used during maintenance.
