Solution

1. Preparation

Gather the following tools and materials:
- Oil filter wrench
- Socket set
- Oil drain pan
- Funnel
- New oil filter
- New engine oil (5W-20 or as specified)
- Rags or paper towels
Ensure the vehicle is parked on a level surface and the engine is off and cool.

2. Lift the Vehicle

If necessary, use a jack to lift the vehicle and secure it on jack stands for better access to the underside.
Safety Warning: Ensure the vehicle is stable before working underneath.

3. Drain the Old Oil

Position the oil drain pan under the oil pan.
Remove the drain plug using a socket wrench; allow the old oil to completely drain into the pan.
Once drained, replace the drain plug and tighten it to the manufacturer's specified torque (typically around 30 ft-lbs).

4. Replace the Oil Filter

Use the oil filter wrench to remove the old oil filter. Be cautious as it may contain residual oil.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter by hand, turning until it is snug (do not overtighten).

5. Add New Engine Oil

Remove the oil filler cap on top of the engine.
Using a funnel, pour in the new engine oil. The capacity is typically around 6-7 quarts (check the owner’s manual for exact specifications).
Replace the oil filler cap securely.

6. Check Oil Level

Start the engine and let it run for a few minutes.
Turn off the engine and wait for a few minutes before checking the oil level with the dipstick.
Add more oil if necessary to reach the proper level.
