If they had used pictures of the actual years they were discussing article could be more credible. When I bought my 99 it had 42k and my uncle says upon inspection, that engine is knocking. 122k mile later, it’s still knocking lol

We have 130K+ on our 2013 5.3 and she's still running great.
Pretty sure the oil pooling/PCV issues had been resolved by the 2013 model year.
She doesn't consume any oil and the plugs were all a nice tan color when I changed them back at 100K miles.
Installed a dongle back around 60K miles that plugs into the OBD2 port and electrically locks-out the cylinder cancellation.
Runs as a V8 all the time with much better drivability.
That along with religious Mobil-1 full synthetic oil/filter changes every 4K miles has worked well so far.
