Whatever you use, just remember that more ZDDP is not better. Too high levels can create a corrosive condition.

From what I read and what Howard told me also is any corrosive issues is only with a super high amount. Like 50ppm. We dont even get close to that at 12-15-19 ppm
I like Chevron Delo, and chevron still shows the zinc/phosphorus amounts in the product data sheet. Shell doesnt. They are both great oils
