Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool if it has been running.

2. Check and Top Off Engine Oil

Sub-steps:
1. Open the hood and locate the dipstick.
2. Pull the dipstick out, wipe it clean, and reinsert it fully.
3. Remove the dipstick again and check the oil level; it should be within the marked range.
4. If the oil level is low, remove the oil filler cap located on top of the engine.
5. Using a funnel, add the appropriate type of oil (consult the owner's manual for specifications) slowly to avoid overfilling.
6. Recheck the oil level after adding oil and ensure it is within the optimal range.

3. Inspect for Leaks

Sub-steps:
1. Visually inspect the oil pan, oil filter, and engine seals for any signs of leaks.
2. If leaks are found, identify the source and necessary repairs (e.g., replacing gaskets or seals).

4. Change Oil and Filter (if necessary)

Sub-steps:
1. Gather tools such as a socket set, oil filter wrench, and oil catch pan.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the oil drain plug and allow old oil to drain completely into the pan.
4. Replace the oil filter using an oil filter wrench.
5. Reinstall the drain plug with the correct torque specification.
6. Fill the engine with new oil (consult owner's manual for capacity).
7. Start the engine and let it run for a few minutes, then check for leaks around the oil filter and drain plug.
