Ok, Now I'm confused after reading about filters....Not sure why but I have always heard that you should NEVER buy a Fram oil filter, maybe some time in the past one burst and cooked a motor and they got a bad rep, really not sure how that got started but now I see that you guys think the Fram Ultra is the best......I have been using Mobil 1 M206 for my 5.3 Chevy pickup because it's a longer than stock filter and I can always find one.....I have also bought a Wix XP in the longer size because they have a full synthetic media but from reading another post about Wix X P vs M1 it said the Wix is only 50% efficient at 30 microns so I would really like to find out number one, how Fram got such a bad reputation and number two, is the Fram Ultra now the best on the market?......Great forum, have learned a lot from being here a short time.....Thanks!
