In this paper we are concerned with the oscillation of third order nonlinear delay differential equations of the form r 2 t r 1 t x ' ' ' + p t x ' + q t f x g t = 0 . We establish some new sufficient conditions which insure that every solution of this equation either oscillates or converges to zero.
