Synthetic back to Conventional Oil

I was told the prior owners used synthetic (Mobil One) but I have no proof. I would prefer to switch back to conventional and run 5w-40w (I live in metro Detroit). I searched old posts but didn't really find a clear answer or maybe there isn't one, just a matter of preference. Any current opinions?
