I will be switching to doing my own oil changes, does anyone use factory oil filters or does everyone use something else? I will be using Pennzoil Ultra performance Oil on the Hemi but I have always used Mobil 1 products on fleet vehicles. Never had an issue so I was thinking about using Mobil 1 filters? Also, I have seen people say hand tight on the oil filters, but there again I have always used a tool to loosen and tighten them. Any information would be greatly appreciated.
