Poor filter.
They tend to pool oil in them better, meaning low oil flow on startup. (Good ole cylinder #6 will love that.)
There's a great site that compares a lot of em somewhere. Fram did very poor. The Mazda one is very nice, especially for the 6 buck price.
Another common alternative is to use the Corvette ZR1 filter, which is larger and provide more filter area... good for those longer-term oil changes when you use synthetic oil.
As for brands, I have used Bosch and Mobil1 filters when I am feeling rich.
For those interested, the Bosch ZR1 filter that fits the MX6 is #3401, Mobil1 ZR1 filter = M1-207.
Where is this site that compares oil filters? I would really like to check this out for myself, since Ive been using FRAM for a while and I just trusted my dad that they were good.
Here's one page. I know there's another that deals in the Mazda filters. I think it may be on Probetalk somewhere, since odds are its someone there that did the tests. But this one at least illustrates the issues with Fram being less then good. Click here
see, Fram has the luxury of having good filters in the PAST. They stopped making their OWN and farmed them out and NOBODY Knows that. Now they are CRAP.
Their air filters are still good but oil is just Really bad
are the Mazda oilfilters and Ford oilfilters the same ones or are they different? if they are different are the Fords any good? Its a little harder to find a mazda service shop than a Ford shop IMO.

I think the discussion on the WalMart filter is that it is a Fram with a different paint job. What you think may be OK may be ruining your motor. www.bobistheoilguy.com

OEM mazda filters come with an anti drain back check valve eliminates dry starts, prevents oil from draining back into your crankcase during engine shutdown.
The only aftermarket 2.5 v6 filter with this valce that I know of is K&N part #hp-1010

ummm...every oil filter has an ANTI drain back valve.
Fram's doesn't work very well but...
It's to stop dirty oil from flowing backwards through the filter when car is off.
This valve has nothing to do with preventing 'dry starts'
I guess your right as far as other filters having the anti drainback vavle I was not aware of that. I was going by what a mazda service dept told me when I first purchased my 626 in 96.After reading fram.com and purolator.com this is only comes in applications that as required by vehicle manufacturer
but this is directly from fram.com:
Anti-Drainback Valve. Some oil filter mountings may allow oil to drain out of the filter through the oil pump when the engine is stopped. When the engine is next started, oil must refill the filter before full oil pressure reaches the engine. The anti-drainback valve, included in the filter when required, prevents oil from draining out of the filter. This anti-drainback valve is actually a rubber flap that covers the inside of the inlet holes of the filter. When the oil pump starts pumping oil, the pressure will unseat the flap. The purpose of this valve is to keep the oil filter filed at all times, so when the engine is started there will be an almost instantaneous supply of oil to the engine.
The oil draining back to the engine should not be an issue at all in our cars (at least the v6's, not sure bout I4) since the filter is mounted almost fully upside down. How in the world would that drain in that position?

Suffice it to say that probably all retail filters have the ADBValve, and it may or may not prevent oil from leaving the filter for the purpose of preventing dry starts. But doesnt it make sense to listen to the guys who cut open filters to see which ones work well and which to stay away from? You probably spend hundreds on two-tone vinyl so get off your wallet and get a good filter. It will only cost you $5 more for a great filter (I pay $3 for AC Delco or Purolator which are both held in high regard).
