Is the smoke BLACK, GREY, OR BLUE?
BLACK is not fully burned carbon. Your engine is running very rich.
Get a tune up, or have the fuel map checked/reprogrammed)
GREY is carbon deposits just old stuff (Normal)
BLUE is oil, something in your engine is worn out.
(Heavier oil could slow this down or special 'old motor' oil to help seals to seal up better.)
And WHITE smoke is usually water vapor. It could be a cracked block too...
And this is gas or diesel.. Just most gas cars do not blow grey smoke..(grey smoke is a standard diesel condition...) usually black or blue.. (or white)
