Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and turn off the engine.
Allow the engine to cool down if it has been running.

2. Check and Add Oil

Step 1: Open the hood and locate the oil fill cap.
Step 2: Remove the oil dipstick and wipe it clean.
Step 3: Reinsert the dipstick fully and remove it again to check the oil level.
- If the oil level is low, proceed to the next step.
Step 4: Add the correct type of engine oil (refer to the owner’s manual for specifications) through the oil fill cap.
Step 5: Wait a minute and recheck the oil level to ensure it is within the recommended range.

3. Change the Oil and Filter (if necessary)

Step 1: Drain the old oil by removing the oil drain plug using a socket wrench.
Step 2: Allow the oil to completely drain into a suitable container.
Step 3: Replace the oil filter using an oil filter wrench; ensure the old filter O-ring is removed.
Step 4: Install the new oil filter, ensuring it is tight but not over-torqued.
Step 5: Reinstall the oil drain plug and torque to the manufacturer’s specifications (usually around 25-30 lb-ft).
Step 6: Fill the engine with the new oil as mentioned in Step 2.
