break in oil
To the best of my knowledge, no automotive mfr. today fills their vehicles with any special break-in oil (though I have heard a rumor that Honda does.) I have seen a bottle of Royal Purple that was labeled as a break-in oil, but think it was intended for newly rebuilt engines. The dealership changes mine and I always specify full synthetic Mopar, which I understand to be Pennzoil.
