Solution

1. Preparation

Tools Required: Oil catch pan, socket set, wrench set, oil filter wrench, new oil, and oil filter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Check and Top Off Oil Level

Remove the oil filler cap located on top of the engine.
Using a funnel, add the appropriate type and amount of engine oil if the level is low. Refer to the owner’s manual for the correct oil specification.
Replace the oil filler cap securely.

3. Change Engine Oil and Filter

Tools Required: Oil catch pan, socket set, oil filter wrench.
Position the oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the old oil to drain completely into the pan.
Replace the drain plug and torque it to the manufacturer's specifications (usually around 25 Nm).
Use an oil filter wrench to remove the old oil filter. Ensure the rubber O-ring comes off with the filter.
Install a new oil filter, applying a small amount of new oil to the O-ring for a good seal. Tighten by hand only.
Refill the engine with new oil through the oil filler cap.

4. Reset Oil Light

Use the vehicle’s menu or OBD-II scanner to reset the oil light after topping up or changing the oil and filter.
Follow the specific instructions for your model to clear the oil warning light.
