Pennzoil is a type of oil that we use in cars to make the engine work properly. Just like how we need food to keep our bodies healthy, cars need oil to keep their engines healthy. Pennzoil is a special type of oil that has been made to do the job really well. It helps to reduce the amount of friction between the different parts of the engine, which can help the car run smoother and use less fuel. When we change the oil in our car, we can use Pennzoil to keep it running at its best!
