What is the method for checking the engine oil level?

[VonAngelina]

Method for checking the engine oil level: Choose a flat road surface, turn off the engine and wait for 15 minutes, then check using the dipstick. Before checking, remove the dipstick and wipe it clean with a tissue, then reinsert the dipstick until the handle is securely fixed in the guide tube. Finally, remove the dipstick, hold it horizontally, and observe the oil level. If the level is exactly at or below the "add" mark, you should add more oil. Engine oil is often referred to as the "blood" of a car, as it serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of the lubricant, determining its basic properties, while the additives compensate for and improve any deficiencies in the base oil's performance, imparting new characteristics and making them an essential part of the lubricant.
