Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to ensure safety while working.

2. Inspect and Tighten Components

Oil Filter:
- Locate the oil filter and check for proper installation.
- If loose, tighten it using an oil filter wrench. Ensure it is snug but do not over-tighten.
Oil Drain Plug:
- Locate the oil drain plug under the oil pan.
- Use a socket set to check if the oil drain plug is tight. If loose, tighten it to the manufacturer's torque specification (usually around 25-30 Nm).

3. Check for Leaks

Inspect the oil drain plug and oil filter area for signs of fresh oil.
If leaks are found, replace the faulty component (either oil filter or drain plug) and ensure proper sealing.

4. Complete Oil Change (if necessary)

If oil level is critically low or if leaks are extensive, perform a full oil change:
- Remove Old Oil:
  - Place an oil drain pan under the oil pan, remove the drain plug, and allow oil to fully drain.
- Replace Oil Filter:
  - Remove the oil filter using the oil filter wrench and install a new filter, pre-filling it with new oil.
- Add New Oil:
  - Replace the drain plug, tighten to the specified torque, and fill the engine with the correct amount and type of oil (consult the owner's manual).

5. Final Checks

Reconnect the battery.
Start the engine and let it idle for a few minutes.
Check for any leaks around the oil filter and drain plug.
Turn off the engine and recheck the oil level using the dipstick, adding oil if necessary.
