Answer 1:

Oil does freeze. Oils (depending on what kind of oil you are talking about) typically consist of long carbon chains. Thus, they are "floppy" and do not form nice crystalline solids when they freeze (like water does) however, they do undergo a liquid to solid transition at low temperatures.

Answer 2:

Oil does freeze; the freezing temperature is just fairly low. Oil is often composed of more than one kind of oil, of which the lighter kinds evaporate off, leaving the heavier kinds with a higher melting temperature behind (i.e. tar). This kind of oil freezes. Salt does not dissolve in oil.
