Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Oil pressure gauge
- Socket set
- Oil filter wrench
- Drain pan
- Safety gloves and goggles
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Top Off Oil Level

Remove the dipstick and wipe it clean. Reinsert it and then remove it again to check the oil level.
If the oil level is low, add the manufacturer-recommended oil type to the engine until the level is adequate.

3. Replace Oil Filter

Using the oil filter wrench, remove the old oil filter. Be cautious as it may still contain oil.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter and tighten it by hand, then give it an additional 3/4 turn.

4. Change Engine Oil

Place a drain pan under the oil pan and remove the oil drain plug using the socket set.
Allow the old oil to fully drain out. Replace the drain plug and torque it to the manufacturer's specification (typically 25-30 ft-lbs).
Pour new oil into the engine through the oil filler cap using the manufacturer-recommended oil.

5. Test Oil Pressure

Connect the oil pressure gauge to the oil pressure sending unit.
Start the engine and monitor the oil pressure reading. It should be within the manufacturer's specified range.
If pressure is still low, further investigation into the oil pump or internal engine components may be necessary.
