ZDDP article in Lubes n Greases

[supercity]

There is a very interesting article on ZDDP in the latest edition of Lubes n Greases. I will look forward to reading part 2. The Author insinuates that higher levels of ZDDP found in modern HDEO and vintage PCMO is not to give better wear protection over modern SN/GF-5 style lubes.

Very informative reading.

There is also an interesting article on page 6 that covers the history of oil makers making complaints about each others advertising. Includes a paragraph on the infamous Mobil vs Castrol fight over "what is synthetic".
