Interesting. I had always thought (courtesy of my dad) that re-oiling oak work surfaces every year or so was a necessary evil. And one of the main attractions of corian etc.!
I would prefer a non drying non toxic oil for a countertop/tabletop. You may have to renew it periodically, but in my view the beauty of wood is how it ages, including the scars, and this kind of oil will be easy to reapply without having to refinish.
Never really messed with it tbh, seems long for a not very durable surface.
Furniture maker colleague uses osmo waterproofing stuff then polyx on oak worktops. I’d use fiddes but generally avoid making wooden worktops anyway.
