I remember when Purolator came out with the PureONE about 15 years ago. They started the war of the 'better' oil filter. 20 micron 99% efficiencies. Synthetic or Synthetic blend media, it was all new. In a world where tin can filters were $2-3, where the (edit - mod) said 96% at 40 microns was good: here was a product that seemed head and shoulders better and cost 2-3x as much.
Mobil jumped in on the game next, and came out with a 20 micron filter that they shoved more media in with deeper folded pleats. They claimed 15k miles "extended" performance. I was in love and bought that one too. Never mind paying $10-$12 for an oil filter. These filters could take out anything down to very high efficiencies.
Now the only 20 micron left is the fram ultra. But this is the orange can company and they are all getting sloppy too. The youtube cut opens are showing many brands with sloppy globs of glue, sometimes chunks of glue on the RETURN side of the media, ready to flow right into your engine and plug a tight passage.
The legendary m1 is now a 30 micro ho hum efficiency. Multiple videos cutting them open show glue slopped on the bottoms and backsides of the end caps. Gone are the crimped end pleats, they just glue the end pleats together. Mobil expects us to pay $12.71 at walmart for my rav4 2021 filter.
I saw some other companies (orange) with glue stains on the backside of the media. And some people are finding these"louvre" steel center tubes have bad stamping and the "louvre" is mostly bent shut.
So I'm now just like (edit - mod)! I"m going with Supertech MPs. They at least have a silicon drainback valve, i can stick a flashlight in and look for glue on the wrong side of the media, and you know what? I think the nylon center support cage is fine. Helps me see defects and you know what else? It doesn't need to hold 50 pounds...just a few, so its fine.
ST MPs have 30 micron 99% ratings. Thats good enough, (edit-mod) same rating M1 makes at 2.5x the price. The oil filter world doesn't seem to want to spend the extra on legit 20 micron media. The whole filter world is run by Harvard MBAs, where they LITERALLY have a case study they teach that instructs students that it is usually easier to just convince people a product is better than actually make it better. None of this is even considered unethical by these vampire training colleges. Charge more, claim more, but supply with common quality or even junk. They make a fool out of every one who wants better and is willing to pay.
Lesson for me is: buy the cheap stuff and just watch for problems. The ST MP4967 i just bought was $5.50 at wallyworld. Fram and especially Mobil: Go pound sand.
