What is the Oil the has the most ZDDP in it , Rotella and Delo have been modified as of January 2007 with less Zinc.
One of the oils I can come up with that has the most Zinc in it is the "brad penn" oil , are there any other oils that are good for older "flat tappet" engines or are there additives to add to the new oil. I am looking for Zinc levels above 1400 , thanks.
