How much engine oil should be added for a 1.5L engine?

[HenryMarie]

1.5L engines are typically found in compact cars, which generally require approximately 4 liters of engine oil. The key is to ensure the oil level on the dipstick remains between the minimum and maximum marks. Engine oil serves as a lubricant for internal combustion engines, with its primary functions being to reduce friction and wear between moving components, as well as to remove sludge (a function of dispersants) and varnish (a function of detergents) from the engine. Engine oil is the lubricant used in internal combustion engines that power vehicles such as cars, motorcycles, lawn mowers, internal combustion engine generators, and many other machines. Within the engine, certain components move against each other, and friction converts kinetic energy into thermal energy, wasting otherwise useful power and wearing down these parts. This can lead to reduced engine efficiency and degradation, increased fuel consumption, decreased power output, and potentially engine failure.
