I'm with you. I bought my z71 2016 12,000 miles ago. I have scoured the Web and have not been able to find any reason to believe gm has fixed this. Or even can. I was very concerned that when I get a few miles on that my oil would start disappearing. I was kinda like I'll wait and see. At 10 k miles and on my second oil change I had a 1/3 of a quart that was just gone and cannot be accounted for??? I said screw it and I ordered a tuner and shut afm off.
I will keep an eye on it and see how this progresses. But I can say I'm getting a consistent 2.5 mpg better ( on highway) in gas milage anyway so...
