Is a bigger oil filter better?


Recommended Posts

I did an oil change this pat weekend. I noticed that the filter was smaller than a soda can. I've been reading on these forums that there are "longer" filter options. My initial thought is "Longer filter means more filter material and more filter material means better filtering." So is there a reason I wouldn't buy the longer filters? Besides the little extra oil it would need?

 

BTW: I've been using Bosch or Mobile1 filters.

Bman - Purolator makes a model, I believe PL14610, that is the exact same spec but 1/2" taller than their spec'd model for the LGT, PL14612.

 

As far as I can tell, they are identical except for that 1/2" difference. I've run both without issue.

 

The extra 1/2" would hold maybe an extra ounce of oil, a bit more filtering capacity, and help cool down the overall oil sump by maybe 1 degree :)

 

Personally, I see no reason not to use it, but I'm still running OEM filters too alot of the time. I don't have a preference, except that I'll buy the bigger filter when I have a chance.

Not sure if this has been covered here, but supposedly Wix introduced a new oil filter for Subaru that supersedes their old 51365 part number.

 

The new filter is 57712 and features the correct OEM bypass valve pressure spec of 23psi.

 

Another option anyway!

Interesting...I tried a couple Wix filters in the past, but they cost more than OEM so I went back to Subaru.

 

I hear that.

 

Plain labeled Wix filters are not only tough to find, they tend to be expensive.

 

You pretty much have to buy Napa or Carquest house brand oil filters to get a Wix/Affinia.

 

I guess Napa's new Subaru filter will have the 57712 p/n.

I've been using the mazda rx8 tokyo roki filters. They are the same price as an oem subaru filter, same bypass pressure, but bigger. I probably wouldn't go out of my way to get them, but the mazda dealership is much more convenient for me than the subaru dealership.

I've got 2 AutoZone shops near me and an Advanced shop a little further. I'm kinda left with whatever they have on their shelves: Bosch, M1, STP....? Of the ones I saw I think Bosch is the best choice?

My 09 is using the Amsoil EA15K13 I believe. I have it written down at home, in my Amsoil file.

 

HAMMWERDOWN recommended I use it. I believe it is longer the other filter spec'd out by Amsoil.

305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).  CHECK your oil, these cars use it.

The Amsoil filters with EA15k are 15k mile filters. :)

This. Mazda dealer is closer. Filter is a bit longer and has more girth. Costs me about 8 bucks I think.
