2010 Nissan Versa Oil lighting

I bought a new versa in May. In the past month and a half I have but quite a few miles on it (over 1700), with moving to another state. Before I moved I did go into the nissan service station because my check engine light came on (I did not put the gas cap on properly). They did a check of the car and everything was ok. Recently my oil light came on. It would come and then come off a couple minutes later. I put oil in the car but the oil light came on again. What should I do?
