Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery for safety.

2. Check and Top Off Engine Oil

Remove the oil filler cap.
Use a funnel to add the appropriate type of engine oil (refer to the owner’s manual for specifications) if the level is low.
Replace the oil filler cap securely.

3. Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Lubricate the rubber O-ring on the new oil filter with a bit of new oil.
Install the new oil filter by hand, ensuring it is tight but not over-tightened.

4. Change Engine Oil

Drain the old oil by removing the drain plug from the oil pan (use a drain pan to catch the old oil).
Allow the oil to fully drain, then replace the drain plug and torque it to the manufacturer’s specifications.
Refill the engine with new oil through the oil filler cap.

5. Test Oil Pressure

Reconnect the battery.
Start the engine and let it idle.
Use an oil pressure gauge to check if the oil pressure is within the recommended range (usually specified in the owner's manual).
