I've been using one of Amsoil's 0w-30 oils for several years but switched to their new Dominator series. I don't have any back-to-back comparisons but am sure there are ET and wear benefits over others, especially conventional oils. I did notice a big jump in oil pressure when I went from 0w-30 to 10w-30, especially through the lights. But it settled down to a more comfortable level when I put in their 5w-20.
Amsoil has several high zinc oils out, including their Dominator series, in a variety of viscosities.
