Around the 1100 ppm - just a tad light on for my liking, I prefer a minimum 1200 ppm.

Someone posted a chart showing zddp levels of various oils, unfortunately I don’t have much luck with the search function so you’ll have to have a look around for it. But it showed that Valvoline VR1 is one of the best for zddp.

And one of the best oils for other reasons too
