School me - Do modern flat tappet cams/lifters need high-zinc oil?

Sadly it never was a lack of zinc in the oil that was killing cams.

All engine oil has zinc in it.

The amount of zinc was reduced but it was never eliminated.

If an oil has 800 ppm of zinc or if it has 1500 ppm zinc when it comes out of the bottle doesn’t change anything.

The difference is the oil with less zinc will run out of zinc sooner.

It’s that basic.

I think a typical oil today has 600 ppm. I think VR-1 is at 1400 ... but it's been a while since I looked and I don't go around quoting it so I may be wrong... lol. What I do know is my engines run great on it...
