I did a search and really didn't come up with much - everything I saw in the search was referencing older vehicles. How's the oil consumption with the 2019 3.0TT? Have they improved that situation any, or are they like the older 3.6's that consume almost as much oil as they do gas? Have they finally mitigated the PCV situation (which is probably where most of the oil goes) to where catch cans aren't really needed?

I have never had to add oil between changes. I used to check it often when I first got the car but now I never check it because it doesn't seem to burn any. I suppose something catastrophic could happen but that would be another story.

Thanks - that gives me some hope that oil consumption has been improved over the older 3.6's.

My 2010 consumed almost as much oil as it did gas.... Ok, maybe I'm exaggerating a little, but it did burn more oil than any other vehicle I've had, and from everything I've read, it's considered 'normal'.
