2012 Silverado LT 5.3L Active Fuel Managemet



I recently purchased a used well maintained 2012 Silverado LT crew cab 1500 4WD with a 5.3L aluminum engine 6-speed tranny, 3.42 gears. The vehicle had 32k miles on it, and I have owned for approximately 60 days and now has 36k on it.


I am curious, did GM fix the oil consumption issue with the valve cover baffle, and nozzle in oil pan by 2012 ? My motor uses "a little oil" (approx 1/2 qrt in 3000 miles) but I am not alarmed yet. The oil I am using and have used in all my vehicles is Mobil 1 5W-30 syn (dexos cert).


I did not find out about the AFM and oil consumption issues until after I bought the truck, and while the truck runs smooth, transition between V4 and V8 is flawless....wondering if I am either lucky or the issues just haven't kicked in yet....


Do you have any insight as to when Chevy introduced the "factory fixes" as standard in the Gen IV engines....
