I currently use Mobil1 5w-30 in my 08 Silverado with a Mobil1 filter, but I am thinking about going to a Wix at my next oil change. I'm not sure if it really matters between the two filters, but is one filter better than the othe when running Mobil1 oil? Should I stick with the Mobil1 or go with the Wix? Are their filter capabilities equal? The Wix is quite a bit cheaper than the Mobil1 and if it filters just as good or better, then I'm gonna go with that one. What oil filters do you guys/girls use?
