Okay, in a month I will be leaving for college. Since I will be going out of state I will have to leave my car at home. During that period it will be driven little since both of my parents have their own cars. I am expecting my sister to be driving it but she still has to get her license. It's an 04 Civic. Before I leave I will be changing the oil and filter. At first I was thinking of dino oil and whatever brand filter I have right now and do and oil change in the winter when I come home. But right now Advance Auto has M1 oil filters on sale for less than $8 so I was thinking of getting a couple and doing a 10k oci with either M1 5w-30 or Penzoil Platinum 5w-30 since the manual says its ok for normal service with dino anyways so I thought a synthetic would be more than adequate. Would Penzoil Platinum be able to handle a 10k oci or should I go with the M1? Also, I am not very familiar with M1 filter numbers so I was wondering if someone could tell me what fits on my Civic. Lastly, would anyone recommend against doing a 10k oci for my situation?
