I agree. I've never had any issues with oil filters, even cheap ones. I've never had an engine wear out or quit from lubrication problems. I get rid of cars for reasons other than engine failure.
I know filters probably vary in the quality of filtration. Maybe Mazda's higher pressure oiling system precludes the use of ultra fine filters. Makers of the premium filters like Fram Ultra, etc , don't make an oil pressure appropriate version specifically for the Skyactive. But I might not use them anyway because I change the oil so frequently.
I would think any of the Mazda filters a dealer supplies for use while under warranty does an adequate job, maybe more than adequate if you use high quality oil and change it frequently. I guess you have to be careful getting aftermarket filters that might fit the threads but not have the right specs.
Wix 57002 is made for Skyactive and I've had Wix recommended by more mechanics and shop people than any other brand. They have them at O'Reilly's and Autozone but not Walmart.
