I haven't paid much attention to filters for a while. Maybe because I have just been buying the OEM oil filters. I've noticed that now days Fram oil filters are many times suggested for use when someone askes about what oil and filter to use. A while back (10 or 15 years, I guess), Fram was the red headed step child around here. It was to be avoided. So has Fram's quality gotten that much better, or has the general quality of the other aftermarket filters gotten worse to the point that Fram looks good now? I just installed a Walmart Fram (whatever the middle tier of the lineup is) on my wife's Seltos. Supposedly good for 15,000 miles.
