I have used both Rotella T6 5w40 with and without archoil and Delo 400 LE 5w40 with and without archoil and I've never noticed any variation in the exhaust vapors cold or hot. Just an observation on my part but I don't believe the oil is your culprit. Maybe others on this site will have more helpful info.

What DTCs do you have? That may help identify the issue.

Diagnostic Trouble Code. A series of letters and numbers stored in the numerous computers in the vehicle. They denote issues that are identified and can help in identifying where a problem exists.
There are apps for smart devices that can read them, like Forscan when combined with a wireless adapter that plugs into your OBD port.
