Break In Oils and Zinc

[Chargerguy74]

It's been raining a lot and I've been inside comparing break in and other high zinc oils lately after getting a great deal on some Lucas SAE 20W50 Racing Only oil and Lucas Hot Rod & Classic oil. The Lucas site is really good for listing their oil and additives zinc and phosphorous contents, other brand's sites, not so much. Anyway, when I was searching the forums prior to my cam break in I found a lot of threads asking what oil to use for flat tappet cam break in. I came across this site while trying to find out what the Comp break in oil had in it, and they list a few along with the amounts of zinc and phosphorous in them, so I just thought I'd share:

Things may have changed a bit since 2011 though when this was written.
