Turbo-related oil smoke is caused by oil getting past the shaft seals. One contributing factor in this is that the oil return from the turbo can get coked up, as this is where the oil is at its hottest exiting the turbo. This causes a restriction in the return. There comes a point where the restriction is sufficient to cause pressurized oil to build up in the turbo - when this happens the oil has to go somewhere, and it goes out through the shaft seals.
Mobil 1 0w40 is a thin 40-weight. Chances are that you have a restriction in the oil return that is enough to block the thicker (when cold) 5w30, but the 0w40 can get through.
