Since Bob has been out for a while not much has been said about the Schaeffer products. With the reduction in ZDDP, wonder what Schaeffer will use to mitigate less AW capabilities. Or do they have ingredients not shown in VOA's.
I don't know how this effects Schaeffer's current product line.
However, I ran an analysis on some Schaeffer's 15w-40 run 6000 miles in an old 4.3L Jimmy.
It showed <10 ppm on barium and <10 ppm antimony. The test was done by John Deere Mar 2003.
