Currently in PCMO's

Synergyn " both 30wts and the 15w-50 "
Mobil 0w-30R
Citgo 10w-30 Ultra Life dino

all over 1400 ppm

Castrol Syntec 10w-40 comes in right at 1300 ppm

If your speaking of OTC oils only

Citgo Ultra Life
Mystik Gasoline Formula 5w-30
Motorcraft 30wts

all over 1200 ppm for now

The question might be what oils have the lowest zinc/phos

Pennzoil yellow bottle
Valvoline All Climate

and on and on

what about castrol gc0w30 or mobil 1 15w50, where do they stand
