I can hear like a rubbing sound

Hello, for rubbing sounds, you'll need to do a physical inspection to determine the source. No real guesswork can be done in this forum - you have to hear the noise and detect the source by searching for it visibly. The change oil light may be coming on to notify you that the oil should be changed. It can likely be simply reset once the service is performed as needed. There is unlikely any correlation between the rubbing sound and the light.
