The best oil for the Jeep 4.0


This is a reply email I got from Shell when I asked about ZDDP content of the new formula Rotella
Thank you for your interest in Shell products.

Our Rotella T4 15W-40 (CK-4) contains about 1200 ppm of zinc and 1100 of phosphous. These are the components of the ZDDP for anti-wear protection.
Rotella T4 15W-40 (CK-4) is generally recommended for older flat tappet cam motors.

Do not buy STP oil treatment for the purpose of Zinc or ZDDP additive. I made this mistake after reading the 15oz bottle stating it's first ingredient is Zinc.
I later found out from STP there is only 5ppm of ZDDP
