Default Oil Filter Comparison 51365, 57356, Blue "Six Star", Blue OEM 12A

Thought I would post up the differences in some commonly used oil filters.

Any ideas who is making & relabeling the Six Star filter?
As well as any of its specs?
It has Subaru part #15208AA060 printed on it.

I can cut this one open after I change it out at the next oil change.
Count pleats, measure surface area, ect....
Justin at allwheeldriveauto has a good article on the differences in subaru oil filters over the years.
Subaru Service Seattle: Subaru Oil Filters Explained - Seattle Subaru Repair
He also has a good picture of that six star cut open next to one that looks like a dealer 12A.
Subaru Repair Seattle Oil Filter | Flickr - Photo Sharing!

I am liking the look of that six star more and more, real end caps, large surface pleat area.
Would like to know some more information on it though.
I will be returning the 51365.

Feel free to copy this over and fill in any information that is missing.
As well as add some additional filters if you wish.

WIX Part # 57356 or WIX Part # 51356 is the best bet.

Has the best filtration spec (best material) and only slightly less volume than the big blue one in your picture. More volume is better as there is more oil available to cool/lubricate, but the difference is probably less than 6oz of oil.

WIX 57356 is only $4.86 at rockauto.com and just a couple dollars more at NAPA. On RockAuto.com look under Mazda RX-8 Grand touring 1.3L 1308cc R2 FI (4)

Dumb question: will the 51356/57356 fit the new 4-bangers with the tighter exhaust clearances? My wife's car is a 2011 OB 2.5.

Also, it appears numbers 51356 and 57356 are being used interchangeably... on the WIX site the specs are almost identical (different paint on shell, different application list, but size and features are same). Which is the recommended PN?

Thanks for the link to your thread.
Yeah I would have to agree phatvw, the 57356 is a very good filter.

I would get whichever one is cheaper; its the same filter, just different paint/packaging. Dunno about fitment on the 2010+ models, but no problem on 2000-2009. My guess is that it won't be a problem on 2010+ either.

The 51356 is the small filter for the newer cars...I think its the 51334(?) that's equivalent to the "six star". I have both of them at the house...one for the OBW and the other for the FXT.

I did run a 51365 on the FXT for a stretch...its a touch longer than the 51356 and had better numbers.

Hey steved that 51334 looks close to the same dimensions but definitely not constructed the same.

That is the filter I run on my outback...

I didn't say the "six star" was a Wix, only that it is equivalent to the 51334, not the 51356/51365 which are significantly smaller in diameter. I have all three Wix variants sitting on my shelf at home and have used them on both my Subarus.

Default Wix filters

They have recently changed the listing for most 4 cylinder Subarus to 7712. Great company and made in America. I have toured the factory and they are all about quality control. Napa number is 7712, the wix number is 57712. They also stand behind their product 100%. They have a constant temperature room just for their measuring tools, test dyes, machines, and filters from first to last in a filter run. Buy American when you can!
