Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical short circuits.

2. Inspect Oil Level and Quality

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check oil level; top off if low.
If oil appears dirty or contaminated, proceed to the oil change.

3. Change Oil and Filter (if necessary)

Tools Required: Socket set, oil filter wrench, funnel, oil catch pan.
Sub-steps:
1. Place an oil catch pan under the oil pan.
2. Remove the oil drain plug and allow the old oil to drain completely.
3. Replace the drain plug and tighten to manufacturer's torque specifications (typically around 20-25 lb-ft).
4. Use the oil filter wrench to remove the old oil filter.
5. Apply a thin layer of new oil to the gasket of the new filter.
6. Install the new oil filter by hand-tightening it securely.
7. Add the recommended type and amount of new engine oil through the oil fill cap.

4. Reconnect Battery and Clear Codes

Reconnect the battery terminals ensuring they are tight.
Use the OBD-II scanner to clear any error codes from the vehicle's computer.

5. Final Inspection

Start the engine and let it idle for a few minutes.
Check for leaks around the oil filter and drain plug.
Ensure the check engine light is off.
