Consider the first-order nonlinear retarded differential equation x'(t) + p(t) f (x(tau(t))) = 0, t >= t(0) where p(t) and tau(t) are function of positive real numbers such that tau(t) = to, and tau(t) = infinity. Under the assumption that the retarded argument is non-monotone, new oscillation results are given. An example illustrating the result is also given.
