Just use good name brand oil and add zinc. I use valvolene high mileage semi synthetic since my motors are old and worn out. And add Camshield zinc additive. Since the motor is fresh I’d just use regular valvolene 10w30 and add zinc. In case you’re not aware they took out the highly effective zinc compounds out of oils due to catalytic converter damage since modern engines all have roller cams. Flat tappet cams need the zinc compounds
