    Four months ago I bought a 2009 Mazda CX-7 with 91,000 miles (turbocharged.) I noticed since the weather got colder, the car is blowing a lot more smoke out of the exhaust pipes in the morning. But when I run the car later in the day - not much smoke. I did research and found excessive smoke out of the exhaust on a turbocharged car could indicate turbo failure. But the engine sounds fine and has good performance. Should I be worried or just being paranoid? I plugged in the OBDll code reader and it said, "No Codes."

    Like regular exhaust smoke. Can hardly see it at all in the daytime. But a bit white.

    Sounds like moister burn off. You get more as it gets colder out.
