The produts you posted only has 2 times EPA tolerance Zinc additave, not enough to protect flat tappet cams and lifters.

Zip.
I have no idea why a 95 or newer engine would need it either?
But anyway I was told break in oil has too much zink to run in regular oil, thats why its "break in" oil.
I was going to run Comp Cam break in oil but not recommended to run all the time.
