I recently saw an oil filter comparison on YouTube. I was going to post a link, but I see there are dozens of them, so look for yourself. Basically it concluded that Wix was the best and Fram the worst. I'm talking about regular filters, not fancy premium ones. That conclusion agrees with what I've heard over the years and I remember seeing bad reports about Fram for decades. Personally I stick with AC Delco (supposedly made by Wix) or Wix brand, when I can get them, but have used Fram when that's all the store had, with no adverse effects as far as I could tell. Opinions? Experiences?
