We establish sufficient conditions for the linear differential equations of fourth order

$ (r(t)y'''(t))' =a(t)y(t)+b(t)y'(t)+c(t)y''(t)+f(t) $

so that all oscillatory solutions of the equation satisfy

$ \lim_{t\to\infty}y(t)=\lim_{t\to\infty}y'(t)=\lim_{t\to\infty}y''(t)= \lim_{t\to\infty}r(t)y'''(t)=0, $

where $r:[0,\infty)\to(0,\infty),a,b,c$ and $f:[0,\infty)\to R$ are continuous functions. A suitable Green's function and its estimates are used in this paper.
