I'm trying to see what filters most are running on their FBs with beehive cooler. I've been using bosch, but I get very different oil pressures with each change, perhaps some bad antidrain backs? I've read bad things about fram, but may chase down Mazda filters if they are available.

I use the same oil each time, but this change, it only fluctuates from 40 to 60ish from idle time 5-6k rpm, just yesterday before the change, it fluctuated between 20 to about 70-75. All guesses given the gauge doesn't have all the numbers.

Stays consistent throughout the change cycle.

Thanks

 

OE filters cheap for what they protect. Same PN for rotaries 1970 the 1994 and maybe even RX8s. This is what I always have used.
$7 well spent.

Thanks Stu, I'll try and find a Mazda compatible filter next change. I use only Honda on my Honda's and Motorcraft on my truck, hopefully there's something Mazda makes today will fit.

 

Then you bought the wrong truck... JK

 

B6Y1-14-302A is the genuine part.

B6Y2-14-302-P1 is a USA sourced part.

Wix is a good alternative as well

 

Perfect, thanks, I ordered 8 of them, that will last 4 years.

What, there's other makers of trucks? 😝

 

I use the Mobil 1 or the K&N filters. They are rated really well. Wix is ok and stay away from FRAM or anything they make as private labels for others,

 

I also normally use Mazda filters.I did order a Wix brand filter for my newest 10AE,but I won't have the oil in there too terribly long before I perform its second oil changed under my ownership.
