How Much Engine Oil Should Be Added During Car Maintenance?

[BrynleeLee]

How much engine oil should be added during car maintenance varies depending on the model and displacement of different engines. The specific quantity should be determined based on the oil dipstick inspection standard of the vehicle's engine. The standard for adding engine oil to a car engine is: the oil level should be between the upper and lower limit marks on the engine's oil dipstick. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines. The primary functions of engine oil are to reduce friction and wear of moving parts and to remove sludge (one of the functions of dispersants) and varnish (function of detergents) from the engine.
