This talk summarizes the present state of molecular gas observations of Palomar Green quasi-stellar object (PG QSO) hosts in the local (z < 0.3) Universe. Thus far, ˜ 1/3 of the sample of ˜ 60 hosts have been detected in CO(1to0), with CO luminosities and line widths comparable to those measured for local ultraluminous infrared (IR) galaxies. A few CO detections are of QSO hosts with narrow lines, suggestive of nearly face-on molecular disks. Further, a few hosts which are featureless (elliptical-like) in optical and near-IR light are observed to be rich in molecular gas, which is indicative of them being late-stage mergers as opposed to gas-poor elliptical galaxy hosts. The CO detections are not limited to lower mass hosts; the hosts of CO-detected PG QSOs span the complete range of absolute H-band magnitudes (MH = -23.5 to -26.5 mag). Finally, the various ways in which the star formation rates of QSO hosts have been estimated in recent years is discussed.
