How Much Engine Oil Should Be Added During Each Maintenance?

Each maintenance requires adding 3.5 to 4.5 liters of engine oil. The requirements for adding engine oil are: 1. The amount added should not exceed the upper mark and should not be below the lower mark; 2. When changing the engine oil, the oil filter should also be replaced simultaneously; 3. Pay attention to checking the oil level, and if any deficiency is found, it should be replenished promptly. Engine oil is the lubricant used by the engine, composed of base oil and additives. The additives can compensate for and improve the shortcomings of the base oil's performance and endow it with certain new properties. The function of engine oil is to lubricate and reduce friction in the engine, assist in cooling and temperature reduction, seal and prevent leaks, prevent rust and corrosion, and act as a shock absorber, earning it the reputation as the 'blood' of the car. Lubricant base oils are mainly divided into two categories: mineral base oils and synthetic base oils.
The amount of oil added during each maintenance varies by vehicle model, so don't just guess. I've driven both compact Japanese cars and large SUVs. Generally, smaller car engines have a capacity of around 4 liters—for example, the Honda Civic specifies 4.2 liters. Mid-size SUVs like the Highlander require over 5 liters. Never rely on intuition; the manual spells it out clearly. Once, I rushed and didn't check, ending up adding an extra liter. The engine noise increased while driving, and the oil light flickered. The mechanic said excessive oil pressure accelerates part wear. Always check the dipstick level: after parking and letting the engine cool, the oil level should be between the high and low marks. Oil quality matters too—choose the right viscosity grade. Full synthetic oil can last over 8,000 km. Regular oil and filter changes are the core of maintenance—ideally every 5,000 km or six months. Safety first: the manual is your compass. Saving trouble is better than saving money.
