Oil Filter Recommendation for Subaru FB20D and Honda K24Z3 J35Z8 J35Y6

[bimmerdriver]

The vehicles are 2021 Subaru Crosstrek, 2008 Honda Accord, 2015 Honda Odyssey and 2017 Honda Pilot.

Amsoil recommends EA15K13 for all four engines. This filter has 11-17 psi bypass pressure.

WIX recommends 57055 for the Crosstrek. I would be using the XP version. This filter has 27 psi bypass pressure. I also looked at Fram and their recommended filters have 9-15 psi or 11-17 psi. I'm wondering why the WIX filter has such a high bypass pressure. Is there any advantage to a higher bypass pressure?

WIX recommends 57356 for the Honda engines. I would be using the XP version. This filter has 8-11 psi bypass pressure. This is in line with the Amsoil filter.

All things being equal, is there any reason to not get the Amsoil filters for all of these engines?

Since you're in Canada, you can get Full oil filters at Napa. They seem to be phasing them out in the US.

So, for the Subaru, get the Full 2-OSB007
For the Hondas, get either the Full 2-OHD004 or the Fram PH7317 which is basically an A02 anyway. If you want something better, get one of the higher 7317 filters

I know it's tempting to consider one filter for all these engines because the Subarus often fit the same Honda filters, but Subarus typically have different bypass specs on the filters that might preclude commonizing.


Bypass pressure isn't a better or worse thing, it's just want a carmaker recommends for their engines and what a filter maker puts in their filters on account of that recommendation. Usually when there's a higher bypass spec, it's because that filter is referenced for an application that recommends it.

If you are staying on top of maintenance, then filter bypass spec doesn't really matter because it should rarely to never open. The lower the bypass spec, the shorter-lived the filter can be. The higher the bypass spec, the more pressure loss the filter can generate before going into bypass.

The only downside to Amsoil filter IMO is cost. They of course do not make their own filters, so there's a good chance particular PNs are available from the actual maker for less cost. That said, filter cost is not a major operating expense, so get whatever you want and enjoy it. $10-$20 for a filter is a tiny rounding error compared to the fuel you will burn over the life of that filter.

As for Honda filters, we have a whole thread going surveying what is out there and deep diving on some of them.

One luxury afforded by Honda's long-time use of the same filter fitment for almost all their engines is that it allows a more in-depth examination of the many different filters that fit. Since 1999, only the S2000 and Acura NSX have used filters other than the common xx7317(Fram)/xx14610(PL)/xx51356(Wix). The NSX used an M22 filter interface that has never been used on a Honda product since. It is out of scope for all subsequent discussion.

I'm hoping this thread can be sort of a "one stop shop" for reference information and will be bumped or updated as the zeitgeist of filters changes...

The short version of that thread is: get a PGI premium filter (MicroGard Select or Carquest Premium) or a Pentius and just get on with life. They are both superbly made, highly efficient filters at very reasonable prices.

Thank you for the reply.

I searched and found that the bypass pressure of the OE Subaru oil filter is 23 psi, so while Amsoil and Fram offer filters with quite a bit lower bypass pressure, the WIX filter is a bit higher.

I agree with your point that the bypass pressure should only matter if the oil isn't being changed frequently enough. That's not the case here.

The best price I can get for the WIX XP and Amsoil filters is almost exactly the same.

The part number for the WIX filter in the referenced thread seems to be incorrect, according to the WIX website. I found 57356, not 51356. The only difference between them, according to WIX, is that the 57356 has a burst pressure of 363 psi, whereas the other has no rating.

WIX recommends 57055 for the Crosstrek. I would be using the XP version. This filter has 27 psi bypass pressure.

I'd like to see the debris sloughing rate on a Wix XP with 27 of dP across the media.

As Zee implied, it is highly recommended to avoid the Wix XP version of the 57055. The Napa Gold 7055 is the same filter and likely cheaper. The 7055 actually has the correct bypass ratings for the FA/FB engines but is 4psi higher than recommended for EJ engines, which will not be an issue. I’ve got some C&Ps on the 7055, and use them on my 07 Impreza because of price and performance balance. Sure there are better filters (synthetic media), and sure most of them are significantly more expensive for minimal return over the 7055.

But, for the love of God, please do not start another Subaru bypass valve pressure discussion! Use the search function (or maybe @kschachn may assist!) because there are at least a dozen threads on this from members who don’t search. They all end the same way… it may matter when using OEM filters, but millions of engines with correct (>23psi) and “incorrect” (8-13psi) filters have run hundreds of millions of miles and it’s highly unlikely either one is responsible for a single engine failure.

Neglect is almost always the true root cause of issues.

Beck/Arnley claims to have teh correct bypass spec for Subaru. The Ecogard/PG and clones also do. The Full brand filters are most likely OE spec, too.

Full is made by Siam Filter, a major OE supplier. Almost every oil filter made in Thailand, OE or aftermarket, comes from Siam/Full.
