I like that their "in house" shows higher zinc then a neutral test lab
A few quotes straight from a big name lifter company last week on which oil to run .. "avoid any newer brad penn as the zinc is down considerably from it once was" .. followed by "if it says lucas oil on it .. its junk" . This call was after my engine builder suggested staying away from Brad Penn for lifter & cam life.
He was not a huge fan of vr1 (silver bottle) either unless you used cam shield Blackstone results of zinc 1300-1500ppm. Schaeffer was suggested which Blackstone found to be 1700-1900 ppm.
Here is another lab .. id love to see results of Brad Penn there if someone wants to send theirs in
