What I use to pull now: What I used just before getting the Sierra: LOL - I call this one "Sledication"

That's a very reasonable reply. At the same time, widespread issues would likely result in manufacture adjustments for corrective measures. A manufacturer doesn't have to perform a recall unless it hits a threshold ratio of affected cases to unaffected, so I suppose one would have to offer an ounce of trust that GM isn't trying to get around the alleged issue, certainly if they're continuing to offer AFM on brand new engine designs. There are probably a lot of variables we're not aware of, but I tend to think the ratio of satisfied truck buyers is significantly higher than that of dissatisfied buyers. I mean, is there some sort of grand expectation that perfection is a minimum requirement? In my case, people asked me what engine I had. When I replied with the 5.3 nobody has said anything but, "Good choice." The majority say because it'll give greater overall satisfaction over the 4.8 - and less overall daily-driving cost than the 6.2 (I suppose they generally mean in gas consumption - but that's subjective as well). I have no opinion on oil consumption or engine issues as I have only 4,700 miles on mine. So far, so good. *Steps off soapbox
