The Importance of Oil Caps
Oil caps, also known as oil filler caps, play a crucial role in maintaining the health and longevity of your car’s engine. They allow you to add oil to the engine when it’s running low, and they also provide a way to check the oil level. But what happens when the engine is hot? Should you remove the oil cap to check the level, or should you wait until the engine has cooled down?
