how often should you change your synthetic oil in months

Synthetic oil should generally be changed at least once every 12 months, even if the mileage interval has not been reached. Most modern vehicles recommend synthetic oil change intervals in the range of 7,500 to 10,000 miles, or up to 12,000-16,000 miles for some. However, a common safe recommendation is to change synthetic oil every 6 to 12 months to prevent oil degradation due to time, moisture buildup, or severe driving conditions. If the car is driven in severe conditions (extreme temperatures, short trips, towing, etc.), the oil change interval should be closer to every 6 months. It is best to follow the vehicle manufacturer's owner manual for specific guidance, but yearly changes remain a good general rule.
