In this paper we are concerned with the oscillatory behavior of solutions of two general classes of second order nonlinear neutral differential equations. The obtained results improve and extend some known criteria in the literature. Two illustrative examples are given to justify our results. Recently a notable interest in obtaining sufficient conditions for oscillation of different forms of neutral differential equations increased due to the importance of this class in many applications in science and technology.
