What are the substances in engine oil?
1 Answers
Engine oil contains substances that are carefully proportioned additives blended by engineers. Engine oil, also known as engine lubricant, consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant and serves the following functions: 1. Cooling and temperature reduction; 2. Sealing and leak prevention; 3. Cleaning and purification; 4. Shock absorption and cushioning; 5. Lubrication to minimize wear; 6. Rust and corrosion prevention; 7. Component protection. The method for changing engine oil is as follows: 1. Use a jack to lift the vehicle, locate the drain plug, and loosen it to drain the oil; 2. Remove the oil filter, place a container beneath it, and drain the old oil; 3. Install a new oil filter and add fresh engine oil.
