How many liters of engine oil does the Tiida need each time?

Tiida requires approximately 4L of engine oil each time. Hazards of overfilling or underfilling engine oil: Overfilling engine oil can affect the normal operation of the crankshaft. It can also increase the vehicle's fuel consumption. When the crankshaft journal runs to the bottom dead center, it will hit the oil and create resistance, affecting normal operation, which is not allowed. Insufficient oil, not enough for circulation and lubrication, is also unacceptable, as it will accelerate wear on internal engine components and cause engine damage. Method for measuring engine oil level: To check if the engine oil level is sufficient after adding oil, refer to the dipstick. The dipstick has two marks, one for the maximum level and one for the minimum level. The normal oil level should not be above the maximum mark or below the minimum mark. The oil level should be between these two marks for normal operation.
