In the present paper we have studied the Sitnikov problem when extended to four body problem with all the primaries as oblate bodies. Here all the three primaries are moving in the circular orbit in the xy plane and fourth particle is moving along the z-axis. First we found the condition to maintain the equilateral configuration of the system, then we determined the equation of motion of the system. Using the Floquet theory, we found the Stability region of the motion depending on oblateness parameter.
