The recommended frequency for oil changes has evolved with advances in engine technology and oil formulations. Here are the key guidelines:
- For most modern cars using conventional or synthetic blends, oil changes are typically recommended every 5,000 to 7,500 miles
- Cars using full synthetic oil can often go longer, sometimes up to 10,000 to 15,000 miles between oil changes
- Older cars or those driven under severe conditions (such as frequent short trips, extreme temperatures, heavy towing, or stop-and-go traffic) may require more frequent oil changes, often around every 3,000 to 5,000 miles or every 6 months
- If you drive very little, most manufacturers recommend changing the oil at least once a year , regardless of mileage
- Always follow your vehicle’s owner manual recommendations, as oil change intervals can vary by make, model, and engine type. Many newer cars have oil-life monitoring systems that alert you when an oil change is due based on actual driving conditions
- Using the correct oil grade and quality as specified by the manufacturer is important for maximizing oil life and engine protection
In summary, for most drivers, an oil change every 5,000 to 7,500 miles is appropriate, with longer intervals possible for synthetic oils and newer vehicles, while more frequent changes are needed under severe driving conditions or for older cars
