I think I'm going try your suggestion, get a Wix and maybe maybe a bit heavier oil, and see if makes any difference. I think the oil recommendation for my '01 5.3 is 5W-30 or 10W-30 and that is what has been used.
For the boat I use the FL1A and SAE 30 oil. That of course I change myself!
For what it's worth....
Changed my Tahoe oil/filter this past weekend, ended up with a Napa Silver filter as they didn't have a Wix for my application (not sure where the Napa branded filter lies in the quality scale or if it has the drainback feature). Also changed to 20W-50 oil. It helped, but didn't eliminate the noise issue. A bit strange, but now it starts and runs silently for about 30 seconds, then has 'the noise' for about a minute. It isn't as loud, nor for as long, as it was. Before, noise was apparent immediately upon startup. Sometimes I thought I had a diesel under the hood. Having an engine that is'full' of oil also probably helps as my rear main seal drips.
