Zinc Dithio-phosphate.

Identical to what ARP sells as lube for torquing studs and bolts. Also
available from GM dealers as "Engine Oil Supplement". Something like $7 for
7 oz.

Common part of the additive package in diesel motor oils, not so common any
more in gas engine oils because it has -some- effect on CATs.

Tends to make flat tappet cams and lifters live long happy lives.
