Amsoil vs. Kubota Super UDT2

[Williy]

When I change motor oil I always try to
fill the filter with oil even if its sideways
at least its half full

Used to but don't bother now as the oil pump will fill it really quick anyway. On my class 8 diesel I do because the filters are vertical and they hold quite a bit of oil.
