Lucas Oil brand around here. I tried it with a giant pucker factor on my 440 that had already been broken n and had some miles on it. It was added to Mobil1 full synthetic oil. It's about the same price as Brad Penn or Penn Grade as it's called these days. So, I'll just use the Penn Grade synthetic blend.

Yep, VR1 here as well. It has the ZDDP in it. I have heard diesel oil has the zinc in it as well.
I have the Shell brand.

The additive is used at break in then use a high(for today) zero content oil after that.
STP reduced the amount of zinc a while back and Iirc added molybdenum (moly).

I recently cleaned out a shed for a friend and came across 8 quarts of 10w 40w unopened, which I was told was around 30 years old.
I wonder if it has a higher amount of zinc

Porcelain in the oil? No way, man....NOT in any of my engines.

I think, much like conventional motor oil, it has been reduced, but not eliminated.
I add a bottle of ZDDP Plus to Rotella T5, just to be on the safe side.
