G'day,
As noted in a previous message I intend to use Mobil 1 15W-50 in Double
Trouble. Unfortunately I decided to do so AFTER I had purchased two five
quart bottles of Rotella T Synthetic 5W-40 (Blue Bottle). I will try and
exchange it at Wal-Mart next summer when I go back to the USA next year but
in case they won't I will use it. I wanted to make sure it has the required
amount of ZDDP so I sent an email to Shell Technical Support. Below is their
response.

Rob,
Yes, Rotella T has 1200 ppm zinc and is fine for your older engine.

Hi,
I have a 1975 Olds Toronado with a 455 cubic inch engine. The engine is
standard and has a flat tappet cam. I have been advised that I should use an
oil that has at least 1200 PPM of ZDDP. I have been advised that Shell
Rotella T Synthetic 5W-40 contains 1200 PPM ZDDP would you please confirm
that.
I do not need to know the actual level a simple yes or no will be fine.
Thank you,
