> Cold oil lubricates better.

By this logic a solid would be the best lubrication, which it clearly isn’t.

If you had solid oil -- i.e., wax -- between your moving parts, metal would not be touching metal, so no wear, but the force needed to move the parts would be large. With cold but not solid oil, the effect is similar, but less.
