I will relay their answer.

It seemed to me a couple of years ago it was easy to find Shell Oil touting their ZDDP content on their web site. Not so today.

I sent this to shell on 12/03/11

"There are a lot of questions having to do with ZDDP in oils for classic/antique engines. which products that Shell sells have ZDDP in them?"

This came to me on 12/5/11;

"Dear Sir,

All of our Rotella multigrade oils have the higher levels of ZDDP
necessary for older flat tappet cam engines.
