Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, oil catch pan, rags
Gather necessary safety equipment (gloves, safety glasses).
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect for Leaks

Use the OBD-II scanner to check for any relevant error codes.
Raise the vehicle safely using jack stands.
Visually inspect the oil filter and oil lines for damage.
Look for oil puddles or stains on the ground and around the engine compartment.

3. Replace Oil Filter (if necessary)

Tools Required: Socket set, oil filter wrench
Remove the old oil filter using the oil filter wrench.
Lubricate the rubber gasket of the new oil filter with a bit of fresh oil.
Install the new oil filter by hand until snug; do not over-tighten.

4. Add Oil (if low)

Tools Required: Funnel
Check the owner's manual for the appropriate oil type and specifications.
Using a funnel, add the recommended oil type to the engine, ensuring not to overfill.
Recheck the oil level after adding oil and adjust as necessary.

5. Test and Monitor

Start the vehicle and let it run for a few minutes; check for any leaks around the oil filter and oil lines.
Monitor the oil level over the next few weeks to ensure consumption has returned to normal levels.
