When I sleep at night I habitually massage my face with oil and then sleep but when I get up in the morning for namaze fajr and I do wuzu with the oil on my face and legs. If I dont do it my namaz will get qaza. So can you please tell me that if my wuzu is correct and my namaz is correct? Or can we do wuzu with oil on my face ?

Oil is usually absorbed and the little that remains is usually not a barrier to wudhu. However if you would like to clean, just a quick wash with soap will remove the extra moisture remaining that may be a barrier.
