Mag 1 oil.

Went down to my local corner store to get a quart of oil. They carry mag 1. I picked out 10-30 as I was looking at it I read the back. It say it now has a zddp additive package. Its cheap at 3.69 a quart. Has anyone had experience with mag 1 oil or know the zddp levels. I'm considering switch to it. Instead of an additive.
