I miss my 800. That thing was a driver's truck. The 4 speed and 3.73s were perfect, it handled better, and was much easier to maneuver than this 2013 tank lol. If the 2000 hadn't been rusting away I'd still have it.

My oil level hasn't dropped at all from 90 miles when I bought it new a few months ago to about 4000 miles, when I dumped the factory oil. This also included an 1800 mile round trip at interstate speeds. Of course, it only has 4000 miles but there was literally no noticeable drop in oil level on the dipstick. I do notice a metallic "tink, tink, tink" echoing off the building when I'm sitting in a fast food drive-thru, for example. My 2000 never did that. Perhaps its just the nature of the AFM lifters? I remember reading about "The Hemi Tick" when I looked something up a couple years ago for a friend with a 5.7 Hemi with DOD and that it was normal....

After reading through all 22 pages of this thread, things sorta blend together but did I not see any 2012's or 2013's with issues? Looking to possibly buy a new 2013 so just doing some research. My 2000 Sierra w/5.3 uses maybe half a quart in 5000 miles, if that.

I have very harsh engagement into reverse and also 2-3 and 3-2 shifts. I thought the trans could be the problem but with the front driveshaft removed, it mostly goes away. Also, driving the truck for more than 1/2 hour usually results in a lessening of this clunking/harshness.
