Abstract This study examines the oscillatory behavior of advanced differential equations, a crucial aspect for understanding how physical and engineering systems change over time. This paper establishes new oscillation criteria for a class of noncanonical nonlinear second-order differential equations with advanced arguments. An iterative approach is used to derive sufficient conditions that ensure the oscillation of all solutions, extending existing results and reducing restrictions on the coefficients. The results are supported by Euler-type equations and numerical examples, demonstrating the applicability and effectiveness of the obtained criteria.
