Jeff is right about conventional oak flooring; however, some oak flooring is chemically treated for stability and, although it is unlikely that the flooring you are talking about is, since you don't know the source as he does, it is worth checking out.

"Acrylic Impregnated Wood is More Stable
Acrylic impregnation marries the properties of wood with the plastic technology developed in the early 50's. Using the absorption ability of wood, two chemicals in solution are forced into the dry wood fibers completely saturating the wood. An outside force is then used to combine the two chemicals (polymerize) into solid acrylic (plastic). This chemical reaction takes place throughout the thickness of the wood. The resulting wood floor product has increased density, hardness, ( see HARDNESS Table of Wood Floor Species ) and wear resistance; and coloration can be inserted uniformly through the thickness of the wood. The acrylic fills the fibers and deters moisture absorption, thereby providing increased dimensional stability. These floors do not require "refinishing," in the pure sense of the word, since the acrylic finish is throughout the thickness. Surface treatment performed occasionally will reveal a brand new floor!
Up to this point the properties discussed have pertained only to solid oak floors, one piece of wood through its thickness. Hold on, because now we're going to take those properties and use them as we change direction entirely."
