Havoline SL Mo-160ppm, B-30ppm Havoline SM Mo-400ppm, B-60ppm MC Semi SL Mo- 0ppm, B-30ppm MC Semi SM Mo-230ppm, B-50ppm It seems that solving the problem of decreased levels of ZDDP while meeting SM specifications was not to difficult to solve. Increase Mo by approximately 230 ppm and increase B by approximately 30 ppm in each of these formulations! Motorcraft semi levels of Mo and B are approximately 80% of Mobil EP levels. My point, none. Just an observation.
