Butchers Block drying out even after using mineral oil?

Hi all, I have an end-grain Acacia Wood butchers block, and I want to learn how to take care of it. The care instructions say “hand wash with warm soapy water and towel dry promptly to best preserve wood periodically apply butcher block or mineral oil to preserve finish and prevent wood from drying out”, but I’ve applied mineral oil multiple times and it appears to be looking pretty dry and light in color after some time. I can’t tell if it’s actually dry or if i’m just not experienced enough to know what it should look like, and I don’t want to over-oil it. Every time I get any bit of moisture on it, it creates a light spot, which makes me think it’s not sealed well enough, but wiping the area again with some water and drying it immediately seems to be enough to get rid of it.

I’ve found a lot of products online with an oil and a wax component, is the wax necessary to help seal it? They’re quite expensive, but I feel like a lot of those are just cash grabs, and food grade mineral oil by itself is dirt cheap.
