Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Allow the vehicle to cool if it has been recently driven.

2. Check Oil Level

Open the hood and locate the dipstick.
Remove the dipstick, wipe it clean, reinsert it, and remove it again to check the oil level.
If low, proceed to top up the oil if necessary and identify the source of consumption.

3. Inspect for Leaks

Visually inspect the engine and undercarriage for any signs of oil leaks.
Use a flashlight to inspect hard-to-see areas like joints and connections.
Apply a UV leak detection dye if necessary to trace leaks.

4. Replace Seals and Gaskets

If any seals or gaskets are found to be leaking:
- Use the appropriate tools to remove the failed seals/gaskets.
- Clean the mating surfaces thoroughly to ensure a proper seal.
- Install new seals/gaskets according to manufacturer specifications.

5. Oil Change (if necessary)

If the oil is contaminated or of the wrong type, perform an oil change:
- Drain the old oil and replace it with the recommended oil type.
- Replace the oil filter as well during this process.
- Refill with the appropriate amount of oil as specified in the owner’s manual.
