Chad, I dont see anything on that link that says they regulate anything...it looks to be a resource for filter manufacturers based in North Americe, and there are only a handful of manufacturers in North America these days.
As far as only a couple manufacturers...well, there are actually a lot.
Like this many:
AMS oil
Champion Labs
EMGO
Fram
Denso
Hastings
Hi Flo
K & N
Perf-From
Purolator
Toyo Roki
Vesrah
Wix
What most people who dislike Fram, me included, dont like about them is their cardboard innards.
You might want to do a search yourself about Fram filters and their construction vs EVERYONE else.
They (Fram) are the ONLY on who uses cardboard endcaps. Their filter media is also not the best, and not even close.
Why on earth would you pay the same amount or more to Fram when you could get a Purolator or AC Delco, or other much better made filter?
Oil can very well be the engines worst enemy. If it cant handle the soot and other buildup in the engine until its changes, it will leave it as deposits, which lead to accelerated wear. The oil has to be able to keep that stuff suspended between changes. The filter only removes the large particles, thats why your oil turns dark...its full of other "debris" that your filter doesnt take care of.
But oil is much easier than filters...just keep it clean.
Most oil is good enough, as are most filters.
At the very least, stick with name brand oil, and anything but Fram filters, although running a Fram is not likely to hurt anything.
Im not trying to start a big argument here, but Ive spent a ton of time looking at oil and filter info all over the place, and hate for people to be mis-informed about their decisions regarding either.
Here is some info on filters, though motorcycle related...
