Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- Socket set
- Oil filter wrench
- Oil catch pan
- Funnel
- Torque wrench
- Gloves
Parts Required:
- New engine oil (5W-20 or as specified in the owner’s manual)
- New oil filter
Ensure the vehicle is on a level surface and the engine is cool.

2. Drain Old Oil

Sub-step 1: Lift the vehicle using a jack and secure it with jack stands.
Sub-step 2: Place the oil catch pan under the oil pan.
Sub-step 3: Remove the drain plug using the socket set and allow the old oil to completely drain into the pan. Reinstall the drain plug and torque it to the manufacturer's specifications (typically around 30 ft-lbs).

3. Replace Oil Filter

Sub-step 1: Use the oil filter wrench to remove the old oil filter. Be careful as it may still contain some oil.
Sub-step 2: Prepare the new oil filter by applying a small amount of new oil to the rubber gasket.
Sub-step 3: Install the new oil filter by hand, tightening it until snug, then an additional 3/4 turn.

4. Add New Oil

Sub-step 1: Remove the oil filler cap on top of the engine.
Sub-step 2: Use a funnel to pour in the new engine oil, checking the owner's manual for the correct capacity (usually around 4.5 quarts).
Sub-step 3: Replace the oil filler cap securely.

5. Check for Leaks

Sub-step 1: Start the engine and let it run for a few minutes.
Sub-step 2: Turn off the engine and visually inspect the oil filter, drain plug, and oil pan for any signs of leaking oil.
Sub-step 3: Check the oil level using the dipstick and add oil if necessary.
