Thick white smoke at start up/copper high in oil analysis

My 7.3 has always had a little white smoke when starting in the cold, seems to be progressively getting worse. Haven't driven it in 10 days and today when I started it, it was around 45 degrees out and blew quite a bit of white smoke. I replaced the GPR with a rancor one a few months back, the GPs were replaced last year with Motorcraft. Injectors are stage 2 from Rosewood and have less than 10k on them. I was running 5w40 mobil oil and it had around 5500 (blackstone said the copper was a little high at last analysis) so I changed that today back to Rotella 15w40 that I've previously run. Fuel filter has around 5500 miles on it. Would the thinner oil cause the smoke? and would the high copper content in the oil be a concern the turbo might be on its way out?

i'd say, if its cold thee ,the 5w/40 is what you wanna run. The copper level, i'd chaulk that up to a turbo rebuild, soon in ur future.
