I don’t know where all of the noise is coming from for the 7.3 since I haven’t had one. When I had a 6.0, I added the factory hood insulation “liner” and starting running Rotella Synthethetic. The combination got rid of a lot of noise.
Btw, the Onan propane generator that many of us have also got quite a bit quieter when I changed the oil to synthetic.
YMMV.
My engine ran quieter running biodiesel rather than straight dino diesel with friction modifiers after the ULSD was released. So I would guess the pump and injectors did contribute to it.
