What is the method for replacing the oil filter?

[RowanMarie]

Replacing the oil filter involves the following steps: 1. Remove the drain plug to drain the engine oil; 2. After draining, clean the drain plug and reinstall it, tightening it securely; 3. Use an oil filter wrench to loosen the oil filter; 4. Apply engine oil to the O-ring of the new oil filter; 5. Hand-tighten the new oil filter onto the oil filter bracket until the O-ring contacts the mounting surface, then use the oil filter wrench to tighten it further. The functions of engine oil include: lubrication, auxiliary cooling, cleaning, sealing and leak prevention, rust and corrosion protection, shock absorption, and anti-wear.
