How many liters of engine oil should be added for a 1.5L engine?

1.5T displacement belongs to the small car category, and adding 4L of engine oil will fill it up, as long as the oil dipstick reading is between the minimum and maximum marks. Below are the functions of engine oil: 1. Reduce wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear of components, an oil film of sufficient thickness needs to be established between the two sliding surfaces to separate them, thereby reducing wear and extending mechanical lifespan. 2. Cooling: Engine oil helps the radiator cool the engine by dissipating heat away from the engine. 3. Sealing and leak prevention: Engine oil forms a sealing ring between the piston rings and pistons, reducing gas leakage and preventing contaminants from entering. 4. Shock absorption: When the pressure at the engine cylinder port rises sharply, it suddenly increases the load on the piston, piston skirt, connecting rod, and crankshaft bearings. This load is transmitted and lubricated through the bearings, cushioning the impact load.
I've driven 1.5L displacement cars a few times, usually requiring around 3.8 liters of engine oil, but it depends on the specific model. For example, the Honda Fit is roughly this amount. Too little oil can damage the engine, while too much may cause leaks or increased fuel consumption. I always refer to the owner's manual recommended values since there are significant differences between brands. During regular maintenance, I have the technician check the oil condition, and the oil change interval is recommended every 5,000 kilometers. I remember using 4 liters of full synthetic oil during the last oil change, and the car ran smoother. Keeping the oil clean while driving is very helpful for extending engine life. Before long-distance trips, I also check the dipstick to ensure the level is between the marks.
