Solution

1. Preparation

Tools Required: Engine oil, oil filter wrench, socket set, oil drain pan, funnel, mechanical oil pressure gauge.
Ensure the vehicle is on a level surface and the engine is cool.

2. Check Oil Level

Sub-steps:
- Open the hood and locate the dipstick.
- Remove the dipstick, wipe it clean, and reinsert it.
- Pull it out again and check the oil level; it should be between the minimum and maximum marks.
If low: Add the recommended oil type gradually through the filler cap.

3. Inspect for Leaks

Sub-steps:
- Visually inspect the oil pan, oil filter, and seals for any signs of oil leakage.
- If leaks are found, replace the faulty components (e.g., seals or gaskets).

4. Test Oil Pressure

Sub-steps:
- Disconnect the oil pressure sending unit wire.
- Install the mechanical oil pressure gauge in place of the sending unit.
- Start the engine and observe the pressure reading; it should be within manufacturer specifications (typically 20-60 psi at idle).
If pressure is low: Investigate further for potential causes like worn engine bearings or oil pump failure.

5. Replace Oil Filter (if necessary)

Sub-steps:
- If the oil filter is clogged or dirty, use an oil filter wrench to remove it.
- Lubricate the rubber gasket on the new filter with fresh oil and install it.
- Tighten according to manufacturer specifications (usually hand-tight plus ¾ turn).
