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 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.

Eventually every filter reaches some point where it causes enough of a pressure drop to restrict airflow. Fuel economy, performance and emissions begin to deteriorate and get progressively worse until the dirty filter is replaced. So inspection at the same time you change your oil would be a good practice. I’ve had my 1998 Ford F150 with a 4.6L SOHC V-8 since new. Crank and cam journals were void of wear and we went back with standard sized bearings.

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. Regardless of the mileage or time, a filter should be replaced before it reaches the point where it creates a significant restriction to airflow.
I can provide images of this engine when it was torn down. Engine is now rebuilt and ready to go back in my truck. Had I taken better care of my cooling system it would never have blown the head gasket.
