The Feenberg scaling procedure, as applied to Rayleigh-Schrödinger perturbation theory, is not size consistent; i.e., the energy error E(AB) - E(A) - E(B) is nonzero if A and B are two different, noninteracting subsystems. The magnitude of this size inconsistency of the Feenberg scaling is determined and analyzed.
