Can you give me step-by-step instructions on how to change the oil in a car?

1. Park the car on a level surface and turn off the engine.
2. Gather the necessary materials, including basic hand tools, fresh oil, and an oil filter.
3. Open the hood and locate the oil filter and oil fill cap.
4. Unscrew the oil filter and drain oil into a container.
5. Replace the oil filter and fill the engine with oil of the correct viscosity rating.
6. Replace the oil fill cap and check the dipstick to make sure oil is at the correct level.
7. Close the hood, start the engine, and check underneath the car for any oil leaks.
