The zinc adheres to metal and is a barrier and protects against high pressure wear, Like timing chains & gears, valve stems , wrist pins, ring pressure on cylinders, crank journals, cam lobes, lifters, push rods, rocker arms, Etc. Any metal to metal contact!

New engines don't need as much, they have less metal to metal contact, Belts instead of chains, roller cams, etc.
