The combined use of experimental viscosity ratios together with ab initio calculations for helium has driven significant improvements in the description of dilute gas transport properties. Here, we first use improvements made to ab initio helium calculations to update viscosity ratios measured for H2, Ar, CH4, and Xe by May et al. [Int. J. Thermophys. 28, 1085 (2007)] over the temperature range of 200–400 K, reducing the uncertainties of the data to 0.055%, 0.038%, 0.067%, and 0.084…
