Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before starting work.

2. Check and Top Off Engine Oil

Tools Required: Oil dipstick, funnel, correct type of engine oil.
Remove the oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate oil type as specified in the owner's manual until it reaches the full mark on the dipstick.

3. Replace Oil Filter

Tools Required: Oil filter wrench, drain pan, new oil filter, and oil.
Place a drain pan under the oil filter location.
