New sufficient oscillation conditions involving lim sup are established&amp;nbsp;using an iterative method. The conditions obtained by this method achieve a marked&amp;nbsp;improvement on all known conditions, requiring at the same time far fewer iterations&amp;nbsp;to determine whether all solutions of the considered equations oscillate, than the&amp;nbsp;other known conditions. Examples, numerically solved in &lt;em&gt;MATLAB&lt;/em&gt;, are provided to&amp;nbsp;illustrate the results and the improvement achieved.&lt;br /&gt;
