I wrote to Valvoline with the following question;
1989 Jeep Comanche 4.0 with 100k miles. Looking for a good oil that contains enough zddp.

All Valvoline oils will contain enough ZDDP for this application, as high ZDDP is not required for a 1989 Jeep Comanche. All of our Valvoline products are suitable for use in this vehicle.

I have been told that my unit has flat tappets and should have at least 1200 ppm.

The 1200 ppm of Zinc is something that would be required for a high performance racing engine with an oversize cam application. Not sure who is supplying this information to you, but any stock flat tappet cam application, only requires around 800 ppm of Zinc for protection and approximately 730 ppm of Phosphorus, as Zinc itself will not serve the purpose. If you would like to use the highest Zinc content product we have, that would be our Valvoline VR1 Racing Oil, with 1300 ppm of Zinc and 1200 ppm of Phosphorus.
