Wondered if anyone else has experienced this or has an opinion. This has happened twice under the same circumstances. In the morning I start the car and run it long enough to move it from the driveway to the street, so my roomate can get out. A little while later I go to leave myself and when I start the car a good amount of white smoke comes from the exhaust. It doesn't continually smoke, just one cloud of it when the car is started the second time and I don't observe anything out of the normal in the running of the engine. Again, I've only noticed this on those occasions of starting it briefly to move it and then again a little later to be on my way. Any thoughts are appreciated.
