Normally I would not reply, but I don't want to ignore your direct question, or the other guy asking for "studies" of filters:
- Toyota has built engines that sludged the oil and died as young as 25000 miles and led to a class-action lawsuit (U.S. and multiple States v. Toyota). They also had minivans where the sidedoor could randomly open (leading to a recall).
- I own 3 Hondas so I love the brand, but I recognize they made some major blunders. They make bad auto transmissions, bad VCM engines, bad belt-driven CVTs, and use bad batteries in their hybrids.
- GM was caught in ignition coverups.
- Volkswagen was caught cheating on smog tests.
- So too was Ford about 15 years ago.
- Takata made junk airbags that ejected shrapnel at passengers, and virtually ALL oems used them. Why? Because OEMs are not perfect. Given all those examples, I fundamentally do not trust any corporation.
- IMHO ;-) :-D
FILTER STUDIES:

- And one other test I cannot find. The owner may have erased it.
Yes these are OLD tests so if you can provide newer ones, I would love to see them. I try to make the best choices using whatever data I can find (as I do on my engineering job). Data from these multiple sources show OEM filters, like OEM oil, is rarely the best you can buy.
