Interesting reading.  I had long suspected that there were only a few manufacturers making all the filters under different names.  Turns out that this guy's investigations agree with my hunch.

I was also surprised to learn that Napa filters are just a Dana/Wix with special paint/labeling.  Its really disturbing when they have two grades of filter, one which is ostensibly higher quality/more expensive, and there is no discernible difference between the two except the paint on the can.

If you dont want to take the time to read the whole series of web pages, here's the scoop - this guy is an an electrical engineer who set out to determine which filter was best for his various cars.  Apparently it set him on a multiyear quest to buy every filter for the engines he had, pull them apart, make some observations and measurements and comparisons.  In the course of this, over 9 years, he compiled a whole lot of evidence indicating that many of our strong brand-name-recognition filters (like Fram) are no different than some other less known brands, because they are all manufactured by just a few entities.  There are a few outliers in there, tho....like the Mahle filters which Porsche uses...he really seemed enamored of those.

I bought one of these things last year and I have been cutting open my filters to see what's inside.  That tool works great and it makes it very easy to cut them open in only a minute or so.  Hadn't really found anything until I cut open the filter on my white jeep a couple of months ago.  It was a Mopar filter; M-90 I think.  The paper filter element had come loose from the bottom and there was a gap big enough to stick your thumb through. I would guess that most of the oil was bypassing the filter element.  I only had a 4,000 miles on that filter, but I think it had been in there about 2 years.

Rebadging is pretty much the norm in a lot of products we buy.

it's the same with batteries too. only a few manufacturers that get rebranded. I bought an advance auto platinum battery because its made by odyssey.

I read somewhere that the only lead-acid battery manufacturer left in US of A is Exide, located somewhere near Tri-cities Tennessee.  Nearly every lead acid battery sold in US for automotive use is an Exide battery.  I can't cite the article, its escaped my memory....
