Solution

1. Preparation

Tools Required: Clean rag, funnel, oil container
Ensure the vehicle is parked on a level surface and the engine is off. Wait for the engine to cool if it has been running.

2. Check and Add Oil

Locate the Dipstick:
- Open the hood and find the engine oil dipstick (usually marked with a yellow or orange handle).
Check Oil Level:
- Pull the dipstick out and wipe it clean with a rag.
- Reinsert it fully and remove it again to check the oil level. It should be between the “minimum” and “maximum” marks.
Add Oil if Necessary:
- If the oil level is low, locate the oil fill cap (marked with an oil can icon).
- Use the appropriate oil type (typically SAE 5W-30 or as specified in the owner’s manual) and pour it into the engine using a funnel.
- Check the level again with the dipstick to avoid overfilling.

3. Inspect for Leaks

After adding oil, inspect the engine and undercarriage for any signs of oil leaks.
If leaks are found, identify the source and proceed to repair as necessary.

4. Change Oil and Filter (if necessary)

Gather Tools:
- Socket set, oil filter wrench, oil catch pan, new oil filter, and fresh oil.
Drain Old Oil:
- Remove the oil drain plug and allow the old oil to fully drain into an oil catch pan.
- Replace the drain plug and torque to the manufacturer's specifications.
Replace Oil Filter:
- Use an oil filter wrench to remove the old oil filter.
- Apply a bit of new oil to the rubber gasket of the new filter and install it.
Add New Oil:
- Repeat the process of adding new oil as detailed in step 2.
