You can do an engine flush if you know that your car was well maintained. Most common burning oil is because of carbon build up on on the oil control rings and the holes get stuck with sludge due to the high heat in that area.
If it's not well maintained, or you don't know the history, the safer option is to actually just change oil more often. Maybe every 2.5k miles, drain and refill. Should help wash the crude out.
Higher viscosity doesn't help if the oil rings are blocked.
