Fully reinsert the dipstick and remove it again.

Check the oil level by looking at the markings at the bottom of the dipstick.

Add or drain any oil as necessary.

Before driving anywhere, start the car and let it run for a couple minutes. While the engine is running, check underneath the car for any oil leaks. If oil is dripping from the drain plug you should first check for any cracks in the drain pan. If there are no cracks, tighten the drain plug.
