Synthetic is an improvement over conventional and can provide better wear protection for Your engine, as well as last longer. On average You will need to change Your oil every 7,500 miles with synthetic and 3,500 to 5,000 miles with conventional. Check Your oil at least once a month to make sure that it is full and free of debris.
