Apart from the FCHC (face-centered hypercube), Nasilowski's Pair interaction lattice gas (PI) is the only known lattice gas automaton for three-dimensional hydrodynamic simulations. Unfortunately, the viscosity of PI is not isotropic. In order to determine the degree anisotropy, we derive fluid dynamic equations for the regime of compressible viscid flow. From relaxation measurements of waves propagating in various directions we compute the physically relevant dissipation coefficients and compare our results with theoretical predictions. Although PI
shows a high degree of anisotropy, we define the mean value of the dissipation tensor as effective shear viscosity...
