Narrative:
During cruise flight; the right engine oil quantity went to zero. We also observed higher than usual oil temperature and lower than usual oil pressure. Neither oil temperature nor pressure ever entered cautionary range or exceeded any limits. Referred to flight manual irregular procedures; limits; QRH (drift down) procedures; and engine out profiles. In addition; we informed dispatch and maintenance. As all this took time and since no limits had been exceeded we had now flown close to a sufficient divert airport. Thus we decided to land as a precaution. Approach and landing uneventful on 35L. We shut down the right engine during taxi in.
