Changing it yearly or every 15,000 miles may be a good recommendation in general. However, inspecting your filter regularly and changing as needed is the best practice.

Keep them on the road with Mobil 1™ High Mileage synthetic motor oil. In 1998, Mobil sued Castrol over the discovery that Castrol was processing conventional oil and calling it synthetic. At the time, Mobil 1 was still created mobil 1 full synthetic using a true synthetic basestock, which is more expensive. Mobil lost the lawsuit, and, as a result, the definition of ‘synthetic oil’ became looser. In response, Mobil downgraded their process to the less expensive process.
