Don't forget about howard coleman's oil thread on ZDDP from last year. That is another thread you guys should read if you're willing to post this thread out to 7 pages.

both Mobil 1 EP 15w-50 and Amsoil 20w-50 have high zinc dosages, another reason I use them

Mobil 1 15w-50 has 1200 ppm

according to BITOG, independent VOAs have confirmed the higher dosage

Amsoil claims "heavy treatment of zinc" but does not give a concentration

Valvoline VR1 20w-50 is apparently 0.14%
