The other day when I posted an oil usage problem, either Lanny or Leon responded saying Phram was a bad oil filter to be using. But it was not stated WHY it is not 'the filter of choice'. Why is the Phram not the filter to use?

Thanks much Cissy Cissy

Mainly because they spend all their money on advertising instead of R&D to make the filters better. Probably someone here can connect you to an actual comparison test. I keep hearing that Mazdas factory unit is quite good.

Because they have relatively little filtration material inside, no check valve to prevent them draining back into the oil pan when the engine is off, and generally inferior quality of manufacture. They spend a fortune on advertising

Hmmm.... sounds like it's finally time for someone to actually disassemble a Mazda filter, 'spec' it out, and see how they really stack up in terms of internal hardware, surface area, etc. Then we can actually evaluate it against the data posted on all the other brands in the 'filters webpage'. Anybody care to venture a guess as to who actually manufactures the Mazda filter?

If you went to the meetings of your local Miata club as a proper Miata owner should, you would have seen one dissected. Poorly made paper junk.
