Hello. I just got my first oil change for my car and found out after the fact that they put on a Fram oil filter. I had asked for something else, but they told me (again, after the fact) that they only carried one kind of filter. I think that I can just take off the filter and put another one on. Is that right? And will having the Fram filter hurt anything if I leave it? I am trying to keep everything as clean as possible to avoid any stuck oil squirters. I had them use Mobil1 oil. If I need to change the filter, what should I replace it with?
