The Amsoil Dominator is not an extended drain formulation. But it's going to be very resistant to oxidation with all that ZDDP. So a 5000-6000 mile service interval should be fine. For street use however, the higher TBN Z-rod, or 10w-30/40 motorcycle oils (TBN > 11.0), might be even better choices.

My suggestion is to look past bottle labels and study the chemical/physical properties of the lubricant you're considering for a particular application....
