The steps for changing engine oil and oil filter are: 1. Remove the drain plug and drain the engine oil; 2. After draining, clean the drain plug; 3. Install and tighten the drain plug; 4. Loosen the oil filter with an oil filter wrench; 5. Apply engine oil to the O-ring of the new oil filter; 6. Hand-tighten the new oil filter onto the oil filter bracket; 7. Use the oil filter wrench to tighten the filter an additional three-quarters of a turn. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It consists of base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while the additives compensate for and improve the deficiencies of the base oil.
