Is it okay to add half a liter less engine oil?

[HaleyLynn]

Adding half a liter less engine oil is not acceptable. Insufficient oil will lead to poor lubrication and cause wear on engine components, while excessive oil will increase operational resistance. The functions of engine oil: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and act as a shock absorber for the engine. It is often referred to as the 'blood' of a car. How to check engine oil: After adding oil, start the vehicle and then turn it off for 3 minutes before checking. This is because changing the oil also requires replacing the oil filter, which initially contains no oil. Starting the vehicle allows oil to flow into the filter. Turning off the engine for 3 minutes ensures the oil settles in the oil pan for a more accurate reading. Remember not to check the oil level on a slope, as the tilt of the vehicle will cause the oil in the pan to tilt as well, resulting in an inaccurate measurement.
