If using AMSOIL AND the AMSOIL EAO Series filter, depending on PRoduct, you can go Up To 25,000 miles or 1 Year under normal driving conditions in unmodified engines. Possibly longer if using oil analysis.

If you are using a wet gauze type filter, you may have to cut the oil changes back.. garbage in-garbage out type thing.
