Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative terminal of the battery to ensure safety.

2. Check and Update Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate oil type (5W-30 synthetic recommended) gradually and recheck.

3. Inspect for Oil Leaks

Visually inspect the oil pan, valve cover, and around the oil filter for any signs of oil leaks.
If leaks are found, determine the source and repair or replace the affected seals or gaskets.

4. Replace Oil Filter

Using an oil filter wrench, remove the old oil filter.
Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new filter, tightening it to the manufacturer's specified torque (usually hand-tight plus a quarter turn).

5. Change Engine Oil

Drain the old oil by removing the oil drain plug located at the bottom of the oil pan.
Allow the oil to fully drain into a suitable container.
Replace the drain plug and tighten to the specified torque (usually around 25-30 ft-lbs).
Refill the engine with new oil through the oil filler cap.
