In this paper some new sufficient conditions for the oscillatory behavior of second order nonlinear neutral type difference equation of the form
$$
\Delta\left(a_n \Delta\left(x_n+p_n x_{n-k}\right)\right)+q_n f\left(x_{\sigma(n+1)}\right)=0
$$
where \(\left\{a_n\right\},\left\{p_n\right\}\) and \(\left\{q_n\right\}\) are real sequences, \(\{\sigma(n)\}\) is a sequence of integers, \(k\) is a positive integer and \(f: \mathbb{R} \rightarrow \mathbb{R}\) is continuous with \(u f(u)>0\) for \(u \neq 0\) are established. Examples are provided to illustrate the main results.
