In the paper we offer criteria for oscillation of the even order delay differential equation %
      ![Rendered by QuickLaTeX.com \[y^{(n)}(t)+p(t)y(c t)=0\]](https://www.carpathian.cunbm.utcluj.ro/wp-content/ql-cache/quicklatex.com-b83c98c21f67870ca3e49bdcb09bf966_l3.png)
We provide detail analysis of the properties of this equation, we
offer necessary and sufficient conditions for oscillation of studied equation and we fulfill the gap in the oscillation theory.
