I was using Motorcraft filters on my jeep, but now I just got a 2011 Scion XB and motorcraft doesn't make a filter that crosses over to my application. I like to buy my oil and filters at walmart, but all they have besides motorcraft filters are fram filters. So, I have an Autozone next door to my work and will probably grab my filters there now. They have Bosch, Mobil 1, STP, Fram (Extra and Tough Guard), AC Delco, and K&N filters. I am running coventional oil ( I may stick with the new Valvoline Nxt Gen) and will change oil every 5,000miles. Which filter do you think would work the best for me?
