Solution

1. Preparation

Gather tools and materials: oil, oil filter wrench, socket set, torque wrench, and a new oil filter.
Park the vehicle on a level surface and allow the engine to cool.

2. Drain Old Oil

Sub-steps:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench.
3. Allow the old oil to completely drain into the pan.
4. Replace the drain plug and torque it to the manufacturer's specification (typically around 20-25 Nm).

3. Replace Oil Filter

Sub-steps:
1. Use an oil filter wrench to remove the old oil filter.
2. Apply a small amount of new oil to the rubber gasket of the new filter.
3. Install the new oil filter and hand-tighten it securely (do not over-tighten).

4. Add New Oil

Sub-steps:
1. Remove the oil filler cap.
2. Using a funnel, pour the recommended oil type (usually 0W-20 or 5W-30) into the engine, referring to the owner's manual for the correct capacity.
3. Replace the oil filler cap securely.

5. Check for Leaks

Sub-steps:
1. Start the vehicle and allow it to idle for a few minutes.
2. Inspect the oil drain plug and filter area for any signs of leaking oil.
3. If no leaks are found, turn off the engine.
