Butter has everything that butter oil has, but also includes the non-fat solids.
I was on the WAP protocol, which recommends Butter oil + CLO, and it's fine to just take a high quality butter with CLO. The Butter oil is so expensive too! If you already have raw butter, that's the best, next best is grassfed. Even pasturized still gives you the precious K2 mk4, if you go for the more yellow-coloured butters.
I personally use Melrose CLO (100% natural A&D) with a New Zealand grassfed butter - nice and yellow! And it has helped sort out my teeth
My point is, unless you have dairy issues, use the whole butter
