Odd puff of smoke from exhaust on startup - sometimes - 2006 C230
If I start the car and move it to the street, then come back in a few minutes and start it again to put it back in the drive, I sometimes/usually get a puff of bluish-white smoke from the exhaust as if the car is burning oil. It doesn't seem to matter if the car is hot or cold, the trigger seems to be several starts and stops of the engine in a short period of time without much actual driving.
I am original owner and this car has basically done this from day one. I've asked a few dealer folks, but never really got a straight or consistent answer from any of them. I'm curious if anyone else has experienced this and if it is indicative of a problem or just the car burning off stored vapors or something that it would normally burn off while driving...

How much oil does the car use?
