How many liters of oil should be added to the Mercedes 274?

[VonMila]

Mercedes 274 can add about 7L of engine oil. Engine oil: Engine oil is a necessity for every car engine, a lubricant created to extend the engine's lifespan. However, it's not the case that the more engine oil you add, the better. The amount should be added according to its specific capacity, and the condition of the engine oil should always be monitored. Fuel saving: It is not recommended to open windows for ventilation when driving at high speeds; it's better to use air conditioning for cooling. Regularly check the tire pressure and wear level. Insufficient tire pressure and severe tire wear will both lead to increased fuel consumption. Driving with windows open consumes more fuel. When the speed is below 80km/h, opening windows is indeed more fuel-efficient than using air conditioning. However, when the speed exceeds 80km/h, the significant wind resistance caused by open windows makes it less fuel-efficient than using air conditioning.
