Gingster my sister had solid wood worktops, they were a nightmare with the constant rubbing down and oiling.
I agree with Oops if they are old style Formica probably best replace as once they are sticky they are finished.
Instead of oiling and rubbing down, clean all oil off solid wood worktops, sand them down, wipe carefully then give them three coats of good varnish, Preferably one recommended for sports halls wooden floors.
They can then be re-varnished every five or six years or so.
If you use the sports hall floor variety it can be water based rather than terpentine based - better for you, the enviroment and the food you prepare in the kitchen.
Although our generation survived a childhood of varnished kitchen tables, trays, floors and wooden staircases quite well all over Scandinavia. And varnish was assuredly terpentine based then.
