I've heard that I should get my car's oil changed every 3,000 miles or so. What does this mean, and why is it important?

The oil in your car needs to be changed regularly because it can become contaminated with dirt and debris from the road, which can reduce its lubricating properties and cause engine damage if not properly addressed. Additionally, changing the oil regularly helps keep the engine clean by removing old oil and replacing it with fresh oil. This will help prevent engine wear and tear and extend the life of your vehicle.
