The frequency at which you should change your car's oil depends on several factors, including the type of oil you use, your driving habits, and the manufacturer's recommendations for your specific vehicle. However, a general guideline for most cars is to change the oil every 3,000 to 5,000 miles (4,800 to 8,000 kilometers) or every 3 to 6 months, whichever comes first.
Modern vehicles often use synthetic oil, which can typically last longer than conventional oil. If you're using synthetic oil, you may be able to go up to 7,500 to 10,000 miles (12,000 to 16,000 kilometers) between oil changes, but it's essential to consult your car's owner's manual for the manufacturer's specific guidelines.
Your driving habits can also affect the oil change interval. If you frequently drive in severe conditions, such as extreme heat or cold, stop-and-go city traffic, or off-road driving, you may need to change the oil more often. Some cars come equipped with an oil life monitoring system that will give you a more precise indicator of when to change the oil.
To ensure the best care for your vehicle, it's a good practice to follow the manufacturer's recommendations in the owner's manual and have your oil changed regularly at a trusted mechanic or service center. Regular oil changes are essential to keep your engine running smoothly and prolong the life of your car.
