93 Grand Am

I just purchased a grand am. I had the top end seals replaced due to a oil leak. Now the check oil light comes on and off. Any one have any idea what would cause this? Any and all information will help.

This seems to be a widespread occurrence in models from 92-95, I know that my '93 does the same. The sensors they put in our cars aren't very good. I don't pay much attention to it.

I had a person look at it and the connection to the sending unit are just dirty. I was told to ignore it. Thank you for your reply.
