I have always filled the filter then poured out the oil that doesn’t soak in. I don’t think it matters. My mechanic doesn’t prefill. Can’t imagine that there’s any harm either way.

So I emailed Amsoil to ask for its position on this subject. They responded and recommended to prefill whenever possible depending on the orientation of the filter.
