Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues during the repair.

2. Check Oil Level

Locate the dipstick and remove it.
Wipe it clean with a lint-free cloth, reinsert it fully, then remove it again to check the oil level.
If low, add the appropriate oil until it reaches the full mark.

3. Inspect for Leaks

Visually inspect the engine and oil pan for any visible oil leaks.
Clean any oily surfaces to help identify new leaks if necessary.

4. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Lubricate the O-ring of the new oil filter with fresh oil and install it.
Ensure it is tightened according to manufacturer specifications.

5. Change Engine Oil

Drain the old oil by removing the drain plug using a socket set; allow all oil to drain into a pan.
Replace the drain plug with a new gasket and torque to manufacturer specifications.
Pour in the correct type and amount of new engine oil as per the owner's manual.

6. Test Oil Pressure

Install a mechanical oil pressure gauge at the oil pressure sending unit location.
Start the engine and observe the oil pressure reading; it should be within the normal range (typically 20-60 psi at idle).
If pressure is low, the oil pump may need replacement.
