Solution

1. Preparation

Gather Tools and Materials:
- Oil filter wrench
- Socket set (for oil drain plug)
- Oil catch pan
- Funnel
- Rags for spills
Safety Precautions:
- Ensure the vehicle is parked on a level surface.
- Allow the engine to cool for at least 30 minutes before starting the oil change.

2. Drain Old Oil

Locate the Oil Drain Plug:
- Position the oil catch pan under the oil drain plug.
Remove the Drain Plug:
- Use the appropriate socket to loosen and remove the oil drain plug.
- Allow the old oil to completely drain into the pan.
Replace the Drain Plug:
- Once the oil has drained, clean the drain plug and re-install it, tightening to the manufacturer’s specified torque (usually around 25 Nm).

3. Replace Oil Filter

Locate the Oil Filter:
- Use the oil filter wrench to loosen the old oil filter.
Remove the Old Filter:
- Ensure the rubber O-ring comes off with the filter.
Prepare the New Filter:
- Apply a small amount of new oil to the rubber O-ring of the new filter.
Install the New Filter:
- Hand-tighten the new oil filter in place, following manufacturer instructions (typically 3/4 turn after contact).

4. Add New Oil

Select the Correct Oil:
- Refer to the owner’s manual for the recommended oil type and capacity (typically 5W-30).
Add New Oil:
- Use a funnel to pour the new oil into the engine through the oil fill cap.
- Add the required amount (usually around 5-6 quarts).
Check Oil Level:
- Wait a few minutes, then use the dipstick to check the oil level. Add more oil if needed.

5. Final Checks

Start the Engine:
- Allow the engine to run for a few minutes and check for leaks around the drain plug and oil filter.
Check Oil Level Again:
- After running the engine, recheck the oil level with the dipstick and adjust if necessary.
