Actually, they may have used the wrong oil this time. I asked my dealership if they use the Pennzoil ultra platinum 0W 40 oil. They said they don’t know. “We just put what comes out of the hose.” I asked this question to the technician, the service manager, and the parts manager. None of them could answer me. So perhaps you got a thicker oil, which could actually be harmful. I don’t know.did my first oil change 700 miles ,its been 6 months , ine had that normal hemi noises at idle , after the oil change totally quiet ,anyone else notice this after the first oil change?
