Zinc and Phosphorus levels for popular oil brands

I started doing my own research after reading that one major thing unique to motorcycle oils is that they contain higher levels of Zinc and phosphorus in order to combat high RPM friction issues.

Not sure if this info is useful to anyone, but I thought I'd share. These are UOA's from other individuals (mostly from "bob is the oil guy"). I am going to find a few more oils to compare to, some more data inputs (will help with accuracy), and possibly a few automotive brands as well. If anyone cares to see the averages after I am done, please let me know.

Zinc average for Rotella Syn 5w40 - 1315
Phos average for Rotella Syn 5w40- 1132

Zinc average for Mobil 1 MX4T - 1556
Phos average for Mobil 1 MX4T - 1320

Zinc average for Redline 10w40 - 1321
Phos average for Redline 10w40 - 1089

Zinc average for Amsoil 10w40 - 1334
Phos average for Amsoil 10w40 - 1144

A real quick comparison from 1 automotive brand:

Mobil1 5w20 - 6,728mi. / '04 Mazda3 2.3L 4-cyl
Zinc - 684
Phos - 614

As you can see, motorcycle oils have a significant amount more of the Zinc/Phos additive. One thing to note is that the Rotella (not motorcycle specific) also has very high levels that are compariable to your expensive motorcycle specific lines.
