Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Check Oil Level

Remove the dipstick, wipe it clean, and reinsert it.
Pull the dipstick out again and check the oil level.
- If low, add the appropriate grade of oil as specified in the owner's manual.

3. Inspect for Leaks

Visually inspect the engine and undercarriage for signs of oil leakage.
Clean any oil-stained areas to help identify new leaks during the next inspection.

4. Replace Oil Filter (if necessary)

Locate the oil filter and use an oil filter wrench to remove it.
Apply a thin layer of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten it according to specifications.

5. Test Oil Pressure

Remove the oil pressure sending unit using the appropriate socket.
Install an external oil pressure gauge in its place.
Start the engine and observe the pressure reading while at idle and at higher RPM.
- A reading below the manufacturer's specifications indicates an issue with the oil pump or internal engine wear.

6. Reassemble and Check

If the oil pressure is normal, reattach the oil pressure sending unit.
Reconnect the negative battery terminal.
Start the engine and monitor for any warning lights.
