[@nickknee3515]

Never thought an hour long video on Subaru oil filters would be so interesting, great job on keeping me enthralled and interested. I've always run Wix/ Microguard filters on my 04 N/A EJ25 Subaru, and this vid just gives me alittle extra piece of mind that I'm using a pretty good quality filter. Thanks for going through all the pain staking cutting and explaining and $ you had to spend to give us people some extra knowledge on what is better for our Subies.

57:00 for the conclusion. Wix/Wix XP (same as NAPA Gold or Platinum) are the best all-around American-made filters readily available at stores, and they are more affordable than AMSoil, Royal Purple, and dealer filters.

Wix makes their filters in Mexico, they are an American brand though.

[@cassial777]

I read that the reason subaru filters are shorter than the mazda filter is because the exhaust pipe on the turbo models runs very close to the filter. they made it smaller to add some distance in an attempt to keep the exhaust from heating up the oil and re-circulating the heat back into the motor.

I have been using Fram a long time, at least 33 years (since we got our first local Walmart). I've put them on vettes, cadillacs, everything I've owned except a mercedes (couldn't find one for it). I put them on the same daily driver for 26 years, over 60 oil changes. The car wasn't using oil when I sold it. I put one on my new Subaru for it's very first oil change. I have also used nothing but synthetic oil since it first came on the market. That being said, I will probably be using Wix or Purolator in the future. Thanks for the video. It was enlightening.

Years ago I read a post on an Audi user forum. The poster went through a very similar process including measuring the square cm of the filter media. What I remember for sure from his findings was that the Fram orange label has the smallest filter media and the Wix and Bosch filters were tied for the largest amount of filter media. After watching this fine video I'll be sticking with the Wix.

[@blazetownsend8785]

You helped me expand what filters I feel comfortable using on my 96 Subaru. And convinced me you avoid the Subaru USA made filters. (Which I never used anyways.) On the Wix filter, I know that the bypass on those push on the spring inside the assembly and oil will pass through the holes. Apparently it's set up like that so you don't flush contaminates from within the filter back into your car. Personally, I have been using Mobile 1/Penzoil Platnium HE for a long time (Seriously, I think they are the same exact filter!.) I would also get the Purlator Boss or Ones. But you opened me up to Mahle and Carquest Premium.

[@rangersmith4652]

I don't know why Subaru stuck with the Tokyo Roki filter for the 3.6, but I'm happy they did. That's what I'll continue using.

[@apicars1287]

TLDR: wix xp or Mazda filter is the best and better than OEM. The OEM filter doesn't even meet the OEM requirements and no other filter does expect wix XP and Mazda.

[@apicars1287]

@Brandon Kilian by pass valve at 25psi and cardboard end caps with synthetic filter and metal clipping it together. Otherwise known as OEM

[@apicars1287]

@Brandon Kilian not to my knowledge. I personally have access to STIs as I'm a Subaru technician.

[@apicars1287]

So the Subaru OEM filter is a Fram Tough Guard which doesn't meet Subaru's own backpass valve pressure specs???...

[@infotechsailor]

I'm sure that the blue OEM frame built has a stiffer spring but that may be it.. I've seen on forester forums it did test at 23psi but still would rather go with black Tokyo roki or Mazda filters any day than use the crappy cardboard end caps

[@richh1576]

Subaru and other engine builders DO NOT MAKE oil filters, they buy their filters from many of the various filter ''foundries" who specialize in private label filters for the automotive aftermarket. With such aftermarket there is NO guarantee of meeting spec. from filter lot to filter lot nor from originating foundry to foundry, especially from Chinese filter foundries. Look at (and know) the UPC 'bar codes' on the packaging for the country of origin. Te be sure ANY automotive aftermarket oil filter meets specification search the internet for domestic 'filter look up' / conversion reference .... then µM removal rating, then sq. ft. surface are of filte media, then rated operating flow capacity (gpm/min or lites/hr/ at (typically) i psig or 1 Bar(g) differential pressure, etc.

[@vnslkd]

Thanks for the great video with good detail on different filters! Filters do matter, I have some experiences with some aftermarket ones: With GM X25XE engine that uses cartridge type filters, I got a WIX filter from parts store. After draining the oil and taking out the old filter, I tried to get the new filter in but something had happened in manufacturing, because the base with the locking taps was too large for the oil filter chamber. So, had to walk few km's back to the parts store and got a Mahle that fit as it should. Couple of oil changes later, I once again got a WIX filter and thought that last time was just some fluke. But no, this one didn't fit either. So back to Mahle for that car. With BMW motorcycle Rotax 650 engine, I got a K&N cartridge filter from the parts store. It did look like a quality part, good finishing etc., but the diameter of the base plate was actually too large to fit into the chamber. So, to the dealer and OEM BMW for that motorcycle. With old Toyota Hiace 2.4D, I once changed the oil and replaced the filter with finnish aftermarket M-filter. Everything was good until in one winter morning, there was about -35 degrees celsius and the block heater cable wasn't connected well enough. I started the car and the threads of that filter just failed, leaving a mess to the yard (good luck I spotted that). Was nice to go through the garbage bin to get the old Toyota OEM filter and fit it that frosty and dark winter morning in order to get going. After that I have only used Toyota OEM with Toyotas. Couple of weeks back I got a new filter for my Subaru H6 from the parts store. Standard option was a WIX filter and OE quality option was Mahle. I did take the Mahle based on earlier experiences :)

[@taconobaka1688]

I've been using Purolator Boss filters on my Toyota 3.4L 5VZ-FE engines in my Tacoma and T4R along with Castrol Edge 5w-30 High Mileage full synthetic. I always had clean engines with Castrol oil and I'm glad I opted to go with Purolator Boss filters. I cut open the one I took off last oil change and my element had a coil spring type bypass valve in it instead of that weird looking one. Oddly on a different video I saw a WIX XP with the same weird bypass valve as the Purolator Boss in this video.

[@escargod]

Great video. I ran it at 1.5 speed and had no issue with understanding him. My question is why the high pressure relief for Subaru's? Is it strictly to pack more contaminants into the filter before it goes into bypass? I can think of no other reason other than the high flow of some Subaru oil pumps. On my race engine I use a large filter on a mount and use a Canton bypass plate. Then I use any large high performance racing filter I choose. Most all have a fairly low bypass pressure. However, I change this filter about every 10-15 hours.

My first Subaru, a 1995 Legacy wagon, I always used factory Subaru. Then after a few years the filters changed color, feel and weight. I found out they were made by Wix (IIRC, this was almost 20 years ago) and Subaru went to Purolator. Being a mechanic I bought a Fram, Purolator, NAPA (Wix and this was before the Gold & Silver designation) and the new Subaru filter. I cut them all open, unused, & what I learned is Never use a Fram or Purolator is you value your engine. Purolator filters have changed drastically since I cut them apart, when I did it around 2000 they had less pleats and filter medium.

If you are among the few DIY like me consider becoming a Amsoil Preferred Customer. I have been a DIY oil change and basic maint. since 1986. I have used Amsoil products the past 15 years. As a Preferred customer you can get free shipping on $100 orders. They sell Wix filters and Amsoil brand which some say is the Wix XP. I like that they offer 3 levels of oil protection (Signature, XL, and OE). I generally use the XL series. They have a lot of product information and vehicle application on the website. Yes, not cheap but I like that they are a U.S. company (made is WI).

I like the extra capacity and media of the Mazda filter, but the anti-drainback spring pressure having a 6psi range of variance makes me lean more toward the Wix XP. Plus, that Mazda filter media has the yellow look of cellulose, so even at 3k miles between oil changes, I would expect less filtration efficiency than the XP's synthetic media.

Another couple options for filter geeks: I just bought the "Full" brand filter 2-OSB002 that NAPA sells in their Altrom line. $6. Looks an feels like a substantial filter; advertised as OES, with 'M pleats' for more filter area, silicone ADB. For applications that require the smaller filter, NAPA also sells the Hengst H97W06 in their Altrom line. $8.50. No doubt a quality filter, though I'm not sure of the bypass valve pressure (personally I am not concerned about that)

Here in NZ Subaru agents supply black ROKI filters. The same filter (15208AA100) is used for EJ207 and FA20DIT (having both cars hence the example). I avoid filters with square O-rings, they are garbage, as they have very high chance of being stuck on the engine, and often leak.

Well done. Very comprehensive and informative. I have owned mostly Japanese cars over the past 20 years and have had good luck (knock on wood) using Wal-Mart purchased Fram filters. I avoid using their Extra guard filters. If I am using synthetic blend oil I will use their Tough Guard oil filter. If it's in a newer car (for my fleet 9 years or newer where I use full synthetic oil) I go with their Ultra synthetic filter which they claim is optimized for full synthetic oil, an added bonus the Fram filters are made in the USA.

Wish you’d found the Amsoil version to see the comparison. It’s an excellent review...thank you.

It is important to know the filter surface area and the thickness of the filter medium. Also the flow rate through the filter medium and the micron size

Ordered 4 denso oil filters from rockauto for 2006 subaru sti. Bee using oem blue filters and supertech oil filters.

Awesome video... thanks!!

[@carlosmoreira779]

Great analysis. Which way does the oil flow?

[@coreyb7761]

Awesome video!! Will the Mazda filter work on EJ257 STI engines?

[@calm7677]

That Mazda filter looks very nice and uniform.

I would like to know if there was any difference in the number of pleats. Looked like that small Mobil 1 filter had more pleats than the other. Filtering capacity and internal resistance. I want to be confident I have good filtering capacity throughout the life of the filter. More pleats seems it would have longer life and less resistance to flow. Also, I would think MICRON filtering differences would dictate bypass filter spring strenght?? Just thinking out loud. Nice video so far. Great job!

[@crankshaft007]

Thanks for the investment for the video, would be nice to measure the filter media for comparison. Can the turbo filters be used on a older NA ? Or the older filter at the end you mentioned for NA, does anyone else make that size filter?

[@nathanshiba6866]

Thanks for the hard work! Would your general brand recommendations change for those of us with the Outback Gen 5 3.6R?

[@MrSubaru1387]

Stick with the oem black filter on the H6.

Thank you for a really excellent video!

Standard Wix (Napa Gold) filters are now made in Mexico. Big difference in quality of assembly compared with the USA made XP (Napa Platinum).

I stopped useing the OEM subaru filters because I had a bad run with them, the last one I used had a ton of fibrous particulates in the oil after i had a oil consumpion test done at the dealership, only reason I noticed it was because of i wanted to see if I had metal particulates in my oil since I was eating 1-1.5q oil every 1k miles and subarus new warranty says thats fine, when i looked at the oil in a clear tub it look as if someone had stuffed part of a paper towel in my oil, I only run royal purple products right now

[@chuckfinley3152]

The filet area of the rx8 filter alone should have it winning
