friend of mine just bought a 1500 Chevy from a used car lot, 171k miles, excellent shape and runs great, no leaks, not sure what kind of oil the previous owner ran. We were discussing oils and he was considering PP 10W30, due to the low noack, but its on the thin side for a 30, or Mobil 1 TDT 5W40, meets SN specs, which I've heard these Vortecs like 40 wt oils. either oil would be run the full duration of the OLM for as long as he owns it. Which would be better or will either suffice? A Napa Gold 1522 filter will be used.
2004 4.8 Chevy

I'm pretty sure they are like the SBC and they can take pretty much anything. In warm climates I would be going as thick as possible.
There are plenty of those engines getting abused everyday with the incorrect grade in the sump.

The 4.8 does not have AFM so run whatcha brung.
Our 04 Tahoe has the 5.3.. same basic engine as the 4.8. It likes 10w30 and i change it every 5k because in ours the olm does not work right.

I had the same truck except it was a 05. It got PYB and followed the OLM with Supertech Ecore filter. It can take anything with modern specs as long as you keep it topped off.
