    Brief oil smoke on startup with 2.0T. Anyone else?

    Since I have remote start, I typically get out of my house and while walking to the car I activate remote start and then unlock the door, get in and drive away (I like the engine noise, what can I say?). I notice a little puff of what seems to be blue smoke (not moisture) that lasts about 1-2 seconds and then goes away. I know I would never have noticed this if I started the car while inside since it's light enough to disappear about 3-4 inches away from the tailpipe. The car has 6k miles and already had the oil changed once (during the CUE update). Otherwise, no funny smell, no performance issues I can see, etc. Any one else notice this?

    Hello Yplus,

    I see that you are reaching out to the community to see if anyone else is experiencing the concern. If you are still concerned, I would suggest taking it to the dealership to have them look at it. If you would like any assistance with working with the dealership, I would be more than happy to assist you. Send us a private message if that is the route you choose to pursue. Thank you very much for your time.

    I think it's a bit of soot/particulates. Look in your tail pipes, they will be black with soot/black particulates. I've had two GM 2.0L SIDI Turbos and this is normal in my experience.

    Yes, I find the tailpipes unusually sooty, and any 2.0Ts I have seen seem to be like that. I say "unusually" in comparison to other cars I have owned.
    M5eater and M5eater like this.

    I think you guys are on the right track. Yes my tailpipe is pretty sooty as well. I actually stared at my tail pipes while activating remote start and it did look like it was actually a little puff of soot, almost like a diesel engine, but it goes away pretty quickly, less than a second.

    Thanks for the help and comments!

    Cool Re: Brief oil smoke on startup with 2.0T. Anyone else?

    I have noticed soot on my tailpipes and think it is normal, though i have not seen smoke. Every week or so I clean the soot off with a wet wipe or moist rag. I noticed similar sooty deposits on a 2013 Ford Escape with the 2.0 Ecoboost that I rented last summer. I am beginning to think this is a normal feature of a direct injection turbos. I don't think it's a problem.

    Not sure where you live or where you park your vehicle--I have not seen any smoke from your car.

    I've got sooty tailpipes too, but they wipe up easily to a shine

    It's normal with a lot of F/I turbo cars.
