The oscillatory behavior of the solutions to a differential equation with several non-monotone arguments and nonnegative coefficients is studied, and some new oscillation criteria are given. More precisely, sufficient conditions in terms of lim sup and lim inf are established, which essentially improve several known criteria existing in the literature. The results are illustrated by examples numerically solved in MATLAB.
