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. Change Oil and Filter

Drain Old Oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug using a socket set and allow old oil to completely drain.
- Replace the drain plug and torque it to the manufacturer’s specifications (typically around 25 ft-lbs).
Replace Oil Filter:
- Locate the oil filter; use an oil filter wrench to remove it.
- Apply a small amount of new oil to the gasket of the new oil filter.
- Install the new oil filter, ensuring it is snug but not overtightened.
Add New Oil:
- Use the manufacturer-recommended oil type and viscosity (e.g., 0W-20 or 5W-30).
- Pour new oil into the engine through the oil filler cap using a funnel.
- Start the engine and let it run for a few minutes, checking for leaks around the oil filter and drain plug.

3. Verify Oil Pressure

After changing the oil and filter, use an oil pressure gauge to check the oil pressure readings; ensure they are within the normal range specified by the manufacturer.
