Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Allow the engine to cool down before beginning work.

2. Check Oil Level

Remove the dipstick, wipe it clean, and reinsert it fully.
Remove the dipstick again and check the oil level; add oil if low.
Use the recommended oil type (e.g., 0W-20 synthetic oil).

3. Inspect for Leaks

Visually inspect the oil pan, filter, and seals for any signs of oil leakage.
Clean any leaks found and replace damaged gaskets or seals.

4. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter hand-tight and ensure no leaks.

5. Change Oil

Drain the old oil by removing the oil drain plug (use a socket wrench).
Allow the oil to fully drain into a suitable container.
Reinstall the drain plug and tighten to the manufacturer’s specifications (typically 30 lb-ft).
Add new engine oil through the oil filler cap using a funnel.

6. Test Oil Pressure

Attach a mechanical oil pressure gauge to the oil pressure sending unit.
Start the engine and observe the gauge reading; it should be within the normal range (typically 20-60 psi at idle).
If readings are low, further inspection of the oil pump and engine internals may be needed.
