2012 Silverado LT 5.3L Active Fuel Managemet

Question

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....

 

Thanks

 

Tony
