Reply to "Amsoil xl 7500"

I'm not comfortable with saying that AMSOIL would have to downgrade their formulations to meet API.

A. Phosphorus is not the only way to built a strong additive package, though it happens to be a relatively cheap way.

B. Last I checked VOA's of ASL and ATM Amsoil showed under 1000ppm phosphorus anyway, so they'd be under the API cap.
