How often should I change my engine oil?

For a modern car driven mostly in city conditions, the general recommendation for changing engine oil is typically every 5,000 to 7,500 miles (8,000 to 12,000 kilometers) or roughly every 6 months, whichever comes first. However, this interval can vary depending on your vehicle’s make and model, the type of oil used, and your specific driving habits. City driving often involves frequent stops, idling, and lower speeds, which can be harder on engine oil compared to highway driving. This “stop-and-go” pattern can cause the oil to degrade faster, so sticking to the lower end of the recommended interval (around 5,000 miles or 6 months) is usually wise. Also, if you use conventional oil, more frequent changes may be needed compared to synthetic oil, which generally lasts longer and performs better under stress. The best approach is to consult your vehicle’s owner’s manual for the manufacturer’s recommended oil change interval. Many modern cars also have oil life monitoring systems that alert you when an oil change is necessary based on real driving conditions. Following these guidelines helps ensure your engine stays well-lubricated, runs efficiently, and avoids premature wear.
