Pre-1997 amount was 1600ppm.
Brad Penn oil is 800ppm.
=====================
Billy, where did you get your figures from?
>From the Brad Penn website:
The Brad Penn. Penn Grade 1. High Performance Oils contain the higher level
of anti-wear (ZDDP - zinc dialkyldithiophosphate) and enhanced film strength
so critical to proper high performance engine protection. The Penn-Grade 1.
oils "typical" 1,500 ppm Zinc (Zn) and 1340-1400 ppm Phosphorus (P) content
provide the needed anti-wear protection to critical engine parts, such as
piston/cylinder walls, roller cams under heavy valve spring pressure and
especially those that employ a solid "flat tappet" type system.
