You will have to carry out an accurate oil consumption test and report back if you want an informed opinion.
What colour is the "smoke"
Brand, and a change in oil viscosity might help as would installing a catch can.
If you are getting excessive blue smoke on cold start up then that would suggest worn valve stem oil seals or worm valve guides.
Excessive blue smoke on hard acceleration would suggest worn pistons, rings, or bores.
Once you report back with the oil consumption numbers, further recommendations will follow.
Are you running OEM cats, sport cats, or decats?
Also with the ambient temperature being a bit cooler, you can expect extra exhaust emissions.
