As most of you DIY owners know, Mazda in their infinite wisdom decided to source their current 2.5 Turbo oil filters from Thailand, instead of the original Tokyo Roki units from Japan. Other manufacturers have done this in the past, Toyota went to Thai sourced filters some years ago (denoted by...

Not liking the latest Mazda 2.5T oil filter after reading this article. What are most people using? Definitely not Fram I hope. Wix 51365? Mobil 1. M1-108a ? I crossed that mobile filter into Wix and discovered Wix now makes 57002 which has the correct 15 micron rating and correct higher 11-14 psi bypass spec, and no drain back valve. Supposedly the 57002 was made specifically for the skysctive G engine. I normally would just go with the Mazda but there is a lot of chatter that filter might not be the best. And yea yea, I know all about not giving Mazda a reason to void my warranty by using a crap oil filter. I am looking past that. I want to find a filter that will be my engines “forever filter”
Nobody knows better than Mazda engineers. They came out specs and manufactured the OEM oil filter to meet ALL required specifications for engines they designed. OEM oil filters will always be better than any aftermarket oil filters, period.
You’ll see all aftermarket oil filters use “one-size-fit-all” approach to save their cost. A single aftermarket oil filter will be listed for dozens or even hundreds of engines as long as it fits.
Wix 57002 and the Napa equivalent came out many years ago claimed to be designed to meet exactly the specs for SkyActive-G 2.0L and 2.5L. Now they claim the same Wix 57002 is also for Mazda’s 2.5T whereas Mazda uses a different OEM oil filter with different specs. Anyone with a common sense can tell the Wix 57002 can’t have “dual” specs to meet both 2.0L/2.5L and 2.5T!
Just stick with Thai made OEM 1WPY-14-302 Denso oil filter that’s the best oil filter available for your 2.5T in the US and you’ll be fine.
Or you can get the same Japanese made Tokyo Roki PY8W-14-302 oil filter installed in factory for your 2.5T from partsouq.com in UAE (also on eBay), and you can get it within a week like you order parts from US online sellers.

Just avoid those confusing OEM “Value” oil filters used by Mazda dealers for lower cost such as PY8W-14-302-MV and PE01-14-302A-MV from Mexico.
