Solution

1. Preparation

Gather tools and materials necessary for the repair.
Tools Required: OBD-II scanner, mechanical oil pressure gauge, socket set, torque wrench, oil catch pan.
Place the vehicle on a level surface and engage the parking brake.

2. Check and Adjust Oil Level

Remove the oil filler cap and inspect the oil level.
If the oil is low, add the appropriate type of oil (consult owner's manual for specifications).
Replace the oil filler cap securely.

3. Inspect and Replace Oil Filter

Using a socket set, remove the oil filter.
Ensure the old filter's rubber O-ring is removed with it.
Apply a thin layer of fresh oil to the rubber O-ring of the new filter.
Install the new oil filter by hand, ensuring it's snug but not over-tightened.

4. Change Engine Oil

Position the oil catch pan under the oil pan.
Remove the drain plug with a socket wrench and allow the old oil to fully drain.
Replace the drain plug with a new washer and torque it to the manufacturer's specifications (typically around 20-25 ft-lbs).
Add new oil through the oil filler cap, ensuring to use the correct oil type and amount as specified in the owner's manual.

5. Test Oil Pressure

Connect a mechanical oil pressure gauge to the engine's oil pressure port.
Start the engine and observe the oil pressure reading.
If the pressure is within the normal range, disconnect the gauge and proceed.
If the pressure remains low, further investigation into the oil pump or internal engine components may be required.
