I'm not familiar with that engine and you dont have universal averages or what the average miles are but the Iron and Copper look outrageously high to me.

Is this a 0w20 specified truck? I'd think a 5w30 would be more appropriate for towing. Seems like a lot of iron/copper. I suppose the numbers are within universal average.

It is a Chevy V8, that explains the iron-wonder where the copper is coming from-does a 5.3 have an oil cooler?

Yeah, it's a 0w-20 specced truck with zero ambiguity about it. We might compare a run or two of magnatec 5w-30 and see how it likes it, but stuck with 20wt so far. This engine has a variable displacement oil pump and cylinder deactivation, but member gonefishing seems to have tried 5w-30 at some point with no apparent issues. I believe the truck is equipped with an oil cooler.
