Hi Brian, 

If your car does not have a service indicator, then it needs an oil service needed every year or 15,000km (9,320 miles) and a more thorough service needed every two years or 30,000km (18,641 miles). Otherwise, go by the indicator, though it should be serviced every two years at a minimum in that case.
