    And not from the rear tires! From the exhaust. Started the cat up to go to lunch today and there was a big cloud of blueish/gray smoke behind me. Anyone else seen this? The car has 575 miles on it so not just burning stuff off the pipes. Followed break in to a "t".............

    I haven't heard of this. Does it do it every time or just once?

    This happened with mine when they started it up on the show room floor. I figured it was just because it was new. Hoping it is now. Here is a video of the smoke at startup, it's the gray HC. Is this similar to yours?

    Yep- Just like that. Except mine is a couple months and 500+ miles. Has yours done it anymore? It just didn't look good!

    Honestly... I don't think that is anything... just moisture condensation in the exhaust. If there is blue smoke that is generally oil... so watch the dip stick. Really though... I don't think that is anything to worry about.;)

    Mine did it a couple of time around 300 miles. Check the oil at fill ups I check on my second tank of fuel and it was almost 1 quart low

    image.jpeg All of my MOPARS due this and usually after they have been sitting awhile. My mechanic theorizes oil in exhaust valve train (and not the expert) which causes this. And I can honestly say I have a bunch of new stuff and my previous 2015 SRT 6.4 Challenger and Charger did the exact same thing. And it usually seems to happen after my vehicles have sat for awhile. My Jeep Rubicon and Cherokee as well as my 2016 Ram 6.4 does the same. And if you sit your car for to long you will hear the upper valve train making a ticking sound. Usually takes a good 15-30 minutes for it to go away. Hope this helps. And no my Diesel 3500 does not do this. And yeah my Harley's do it also. Oil and gas what can you say

    I have not checked. I just got it Friday and it has rained all week so I haven't driven it yet.

    It is good to read some of the thoughts that it is nothing as I originally thought it was because it sat for awhile. I was also thinking because it hadn't had a chance to get to our operating temp between all the startups. I will keep an I on it.

    My '15 SRT 392 car did the same thing randomly. Just traded it in so i never pursued it. Im thinking its fairly normal. The new HC hasnt done it yet but i have almost exactly the same miles as you right now. I do keep an eye out for it though considering the last car did it. Time will tell.

    Blueish exhaust means oil is being burned, I would continue to monitor it and your oil level.

    I am not a mechanic but isn't this what any pcv system on a vehicle promotes? The ability of the lost oil vapor to be returned back to the intake and eventually burned up by the engine? I may not truly understand the other posts I have read, but I am thinking that it is for this very reason that others on here recommend a catch can. Supercharged engines have a higher ability to push the oil back so a catch can prevents a majority of the oil return.

    By the way, I am a bottle blonde. :D
