Good Afternoon Dave
Thank you for your enquiry re ZDDP.
I can confirm that this oil is suitable for the Flat Tappet Engines, also I have attached confirmation that you can most definitely use our Trident 10w40.
The Zinc contents are as follows :
Zinc - 1098 ppm
Phosphorus - 997 ppm.
Hope this helps
Kind Regards
Colin
