they have to provide an MSDS sheet with their oils. this sheet lists all of the ingrediants in their product. them telling ,they can't tell you is pure BS!!!
it's required , period!!! STP has red bottle out, they state it has more ZDDP in it, regardless, todays motor oil will require an additive. GM has pulled their EOS, they have a new product,#12345501 ,cam& lifter prelube.
