Nippon Denso Toyota Filter not the new Fram.
Japanese built 4 cylinder engines appear to get High Moly 500 ppm + Break-In Group I Oil. I would run this out for awhile
US Built V6 and V8 engines appear to get a Normal Group II production oil with modest levels of Moly.
If your 4 cylinder is Japanese Built I would run it 6 months or 2000 mi which ever occurs first. If you want to dump it sooner, first make sure the oil is at full operating temp and do a full throttle blast from 2000-5000 rpm in third gear (second for a automatic) and then let the engine decelerate against the gear back to 2000 rpm. Repeat five times. Let Cool. Then do the same thing again taking the engine to 6000 rpm. This should ensure the rings are fully seated before dumping the break-in oil.
