[DeTomaso] ZDDP - is this stuff any good?

[fresnofinches at aol.com]

 The ZDDPlus website makes it hard to find the ppm levels created when using their product, but an obscure 'LINK' button takes you to a tech report that provides this information.


 This link will go to a link for a pdf file that shows ppm levels of phosphorus in 5 quarts of oil in relation to the ounces of ZDDPlus used.

>From this chart, 4 ounces (one bottle) would bring phosphorus levels up above 1200ppm in a typical Pantera ten quart (actually around 9 quarts) oil pan.

Since ZDDPlus has higher a concentration of zinc to phosphorus, it follows the zinc levels would also be brought up into the 'safe' range.
