Dealer installed a black oil filter for 3.6L on my OB13 2.5L in the latest oil change. I believe it is a mistake.
Should I keep it and wait for the next oil change?
Or ask the dealer to reinstall the right one for me NOW?


BTW, I have another question about oil filter.
For 2013, the part number for 2.5L on the manual is 15208AA12A
However, on subaruonlineparts.com, the part number is 15208AA15A
:(
So, confusing!

On page 11-14 of my 2013 Outback Owners manual and of the 2013 manual on the Subaru website:
Model: 2.5 L Oil Filter Color: Blue Part Number: 15208AA15A Amount of Rotation: 7/8


Take your car back and have them install the correct oil filter. They won't learn from their mistakes if they are never corrected on it.

Could you please check the part number on your filter. If it is
15208AA130, and is black made by Tokyo Roki Co, Japan, then it is the correct part number that is given as the replacement filter for 2.5L FB engine in Forester. I believe that this filter is compatible with 2.5L FB engine in your car, even though it may not be listed on your manual.

If the part number is 15208AA031, then it is the oil filter for 3.6R engine, which is also black in color and made by the same company as above, and, of course, you do need to take the car back to the dealer.

While the dealer did install the incorrect filter (should have been the 15208AA15A), that filter is currently unavailable. The correct filter being used as of right now is the 15208AA160.

Please make sure the parts department is aware that they are giving out the incorrect filter.

15208AA130, and is black made by Tokyo Roki Co, Japan, then it is the correct part number that is given as the replacement filter for 2.5L FB engine in Forester. I believe that this filter is compatible with 2.5L FB engine in your car, even though it may not be listed on your manual.
The 15208AA130 is correct for early 2011 FB engine Foresters and BRZ only. In late 2011 and for 2012-2013 FB engines, the correct filter is 15208AA160.

I was under the impression that 15208AA130 being used as the replacement for factory filter 15208AA160, and, they are compatible.

By the way, 2011 Forester has FB25 engine and BRZ has FA20 engine and they are different (with bore and stroke).

So, FB25 engine in 2013 Outback is different from FB25 engine in Forester? I thought that they are the same.

Nope, the 130 (fat filter) and the 160 (skinny filter) according to Subaru are separate listings. To make it more confusing, Subaru says that the 2011 only using the 15208AA130 can be interchanged with the 160, but the 2012-2013 must use the 160 only. Can they be interchanged? More than likely.

You are correct that the BRZ has a different engine. The 130 is the Subaru spec'd filter for it.

We haven't figured out why the Outback and Legacy got this taller filter (015) and the Forester has the shorter one (160). It's a mystery to us.

According to Subaru, the 130 has not been superseded to the 160 because it is supposed to have applications in future models. We shall see.

Pure speculation: (the Internet's specialty!)

Maybe the filter factory can't make enough of either model to satisfy production needs for both cars, so they put size A on one car and size B on the other. It often boils down to something that simple.

I think it is due to location of manufacturing. Forester is made in Japan and comes with Tokyo Roki filter (similar to Impreza) and Legacy and Outback are mode in US, so, they are fitted with Honeywell sourced 15208AA15A filter. I would imagine that SOA will in future, replace all 15208AA160 filters with 15208AA15A like the way that they did with 15208AA12A filter over 15208AA100.

That is very likely. Subaru does silly things (cost effective-wise) like this quite often. It's almost as if SOJ is telling SOA "Use x amount of the JDM parts before going to other sourced parts exclusively."

This too is speculation :17:

People know that, at least for older 2.2 and 2.5 l engines, the blue filter superseded one or more black filter part numbers when it came to the market. But the black filters are still being sold, and preferred by many.
Also, the short filter is specified for turbo models where it has to clear the exhaust, but is generally interchangeable with long filters on naturally aspirated engines.

Before this latest introduction of new filters, SOA had only two. The 15208AA12A blue Honeywell filter, and the 15208AA031 black Tokyo Roki filter. The 12A is spec'd for all 4 cyl engines (turbo or non), the 031 for 3.0 and 3.6 engines. All of the old Tokyo Roki black 4 cyl filters have not been available for years.

Can you use the 031 on a 4 cyl? Yes, if there is clearance.

I confirmed that at my 2013 owners manual.

I can see that as being quite plausible.
Re: 2010-2012/15208AA12A vs. 2013/15208AA15A both 24psi/M20x1.5 AFAIK, is there a performance diff?

Could you please check the part number on your filter. If it is
15208AA130, and is black made by Tokyo Roki Co, Japan, then it is the correct part number that is given as the replacement filter for 2.5L FB engine in Forester. I believe that this filter is compatible with 2.5L FB engine in your car, even though it may not be listed on your manual.

If the part number is 15208AA031, then it is the oil filter for 3.6R engine, which is also black in color and made by the same company as above, and, of course, you do need to take the car back to the dealer.
I checked it is a black 15208AA160.

Sorry, I made a mistake, it is not a 3.6L filter , but it is a black. So I had thought it is for 3.6L instead of 2.5L without careful double check.

So,I can keep this filter on my car, right?

But, IT IS confusing!!!

I do have enough clearance to fit 031 filter on my 08 Outback (naturally aspired engine) with turbo style exhaust manifolds. I am, however, concerned that heat in exhaust manifolds with this filter may heat up oil in the filter causing detonation issues in the engine. What do you think? If I use an oil with higher viscosity, and, in cold weather this may be OK, I guess, but, I do not have any scientific study to back my claim. (I need a heat transfer analysis.)

I think that additional filter material in 031 should not cause an issue for the oil pump as bypass valve is supposed to open up at 23PSI in both filters. Please correct me if this statement is wrong.

You can...maybe. The reason SOA has superseded the 15A to the 160 is because certain batches of 15A filters are being sent back because they can leak. One of the Subaru parts vendors posted it on the forum today. I'll see if I can find it.

Not that I'm aware of. It could be nothing more than Subaru felt the filter should be taller so it is easier to get more of your hand on it to turn it.

Here's a black 4-cyl. filter in a vendor's store, Black OEM Oil Filter 6 pack + Crush ring Non-Turbo 2012 2013, SubaruGenuineParts.com
As to running H6 filters on 4-cyl. engines, it seems there's nothing wrong with that (but not the other way around). This is a circa 2003 quote from Endwrench, found on clubwrx:

Subaru H-4 engines come from the
factory with an OEM P/N 15208AA060
oil filter. The same part number is used
for replacement. H-6 engines come
with an OEM P/N 15208AA031, and
S0A5165109 is used as a replacement.
Both filters have the same physical
dimensions as far as threads, O-ring,
and bypass valve opening pressure (23
p.s.i.) are concerned. However, the H-4
filter has 141 square inches of filtration
surface, while the H-6 filter has 201
square inches of filtration surface.
The H-4 filter should not be used on
the H-6 engine. Using the H-4 filter
may cause it to become contaminated
faster and allow the bypass valve to
open, allowing unfiltered oil to circulate
through the engine.
