Yeah I don't understand the thought of avoiding SkyActiv OEM oil filters either. If they're getting "custom-made" Wix 57002 filter (or Napa 7002 made by Wix) that may make some sense but Wix/Napa filter usually is more expensive than SkyActiv OEM filters. SkyActiv-G requires "high-flow" oil filter. High-flow filter usually makes filtering efficiency suffer with higher micron ratings. But those high-flow SkyActiv filters have 15-micron media rating which are also high efficiency filters! I don't know why some here even endorse 30-micron Mobil 1 filter calling it a quality filter?Good info here, yrwei52, as always. The only reason I call the MV filter cheaper is the wrench stamping on top, it's inconsistent as hell. Been through a half dozen of these things already and sometimes the filter wrench will fit and sometimes it won't. I've cut a few open myself and the insides fit the bill. I've always used OEM, they're fairly inexpensive so I don't understand why people think they're getting a better deal with aftermarkets. And yes, having no ADBV makes sense, thing is upside down so where do people think the oil is going to go?
Again, I'll quote an SAE paper on oil filter efficiency from GM engineer David Staley: Compared to a 40 micron filter, engine wear was reduced by 50 percent with 30 micron filtration. Likewise, wear was reduced by 70 percent with 15 micron filtration.
Between currently available 2 SkyActiv OEM oil filters, I feel 1WPE-14-302 Thai filter is better made than PE01-14-302A-MV Mexican filter. My Mazda dealer always carries both SkyActiv OEM oil filters. Thai Denso filter is available online, and Mazda dealers can always order one for you within a day with a correct part number if they don't stock it. Blame it on Mazda North American Operations who discontinued excellent Japanese Tokyo Roki filter which makes many SkyActiv owners wonder.
