OMG! Ok first off your Subaru dealer is a F***ing crack head! There are only two types of oil they should be offering in full synthetic maybe one more depending on availability So if they dont offer you Subaru OEM full synthetic or mobil one full syntheic both being 0w20 which is the oil needed for your engine in your XV Crosstrek. Secondly I am so happy to see someone else knowledgable about the bipass spec for the oil filter. FYI if you dont use subaru OEM during your warranty you will VOID it faster than a pirannah picks the bone off a fish! Yes purolater makes their filters with Subaru Bipass valve PSI. But I wouldnt use it until after your warranty is up just to be safe! Btw my recommendations for the XV engine during warranty is OEM for everything minus the air filter. with the 8.9 inches of clearance it makes changing your oil easy especially since the oil filter is on top now as well! All you need is a cheap rachet and you can find an oil filter wrench socket on Amazon along with oil filers granted they are the blue honey well ones for cheap. and BAM 20 mins depending on how long you want it to drain. you save yourself ALOT of money.

Not to mention the Subaru full synthetic oil (made by Eneos) is wicked affordable! And the filters are a good price as well.

Technically speaking Subaru can not void your warranty for using another filter unless they can prove that the filter directly caused a failure. (Magnuson–Moss act and other laws prohibit them from forcing you to buy OEM parts only.) However, if that filter has a different bypass valve pressure and you have an oiling issue resulting in engine failure then it will be blamed on that filter and you'll be SOL.

It's Idemitsu for North America. Though I am well-aware Eneos makes excellent synthetic motor oils.

Subaru-Branded Synthetic Motor Oil



In 2010, Subaru of America, Inc. partnered with Idemitsu Lubricants America Corporation to prepare Subaru-branded synthetic motor oil for applications in the new FB four-cylinder engine and in turbocharged engines. Researching and formulating Subaru engine-specific 0W-20 and 5W-30 synthetic motor oil ensures quality, performance, and, ultimately, customer satisfaction. This oil is available to do-it-yourselfers at Subaru dealers.

Oh lame! We order the crazy Eneos branded stuff still but I didn't realize they had swapped the OEM dealer oil over. Thanks for the info! Still decent oil though!

Ah now that is good stuff to know but you have to admit subaru oil filters are cheap and why take a risk. Even if nothing happens I want the correct oil bipass value psi for the fact that i want my car running forever. Every little thing counts toward that effort!

Yeah, the blue Subaru oil filters made by Honeywell (FRAM) are cheap, but they do the job. Aftermarket FRAM oil filters that "fit" do not necessarily have the correct specification bypass valve.

For most, this is good enough. However, for enthusiasts, metal end caps of the Purolator are very much appreciated, especially since it does meet the Subaru OEM specs.

I would pay the extra money for purlator only if i had a high performance engine such as the BRZ WRX STI. the cheaper OEM blue honey well filter is perfect for everything else. Like the XV its small cvt maximizes your RPM so I would stick with OEM in this case because I dont think there will be a difference if you use either one on our engine.

Do it yourself folks. Anyone tried a K&N (p/n: HP-1008) filter?
Click to expand...
I just did my first oil change earlier this evening, I used the K&N HP-1010. The 1010 is the same size as the oem filter, the 1008 is smaller. When I had a WRX I always used the biggest filters that fit, I usually used the Purolator Pure one filters because they were much bigger than most recommended filters from other brands, and I changed the oil every 3k on that car. I definitely do not want to put a smaller filter on this car for 7.5k intervals.

I did notice on the Purolator site they are now making synthetic specific filters which hold more debris than the pure one but they don't seem to be marketing it as a better filter, just a longer service life filter. Anyone have any info on the Purolator synthetic filter, it's valve spec and when/if it will be available for the crosstrek (there isn't a pending release part number when I use their filter finder)? Also, can someone explain this bypass valve issue? Is it for keeping more oil in the filter, letting it flow out easier or something else? I don't understand how it can be such a big deal as long as the oil is going through the filter media.

The bypass valve is a fail safe that allows oil to pass through in the event that a filter clogs or is not flowing enough oil. It's purpose is essentially to keep the engine oiled no matter what. If you had an incorrectly functioning bypass valve you can have high pressure pre filter if the filter is clogged and low pressure post filter. The high pressure pre filter (I.e. oil being forced against the clogged filter) could damage seals. The larger issue however is not being able to pull enough oil through the filter. If that happens you're effectively starving the oil pump which could do serious engine damage.

Important information, which begs to ask: What's in your oil filter?

The following is for reference only and does not address oil filters for the XV, both OEM and aftermarket, but in the likelyhood they will be similar, you have to ask yourself: Do you feel lucky?

Glad to see you linked that! I remember that thread being super informative. I haven't been on SF.org in a LONG time. I used to be on there quite a bit back in the day, had one of the first slammed foresters out there. Sadly I found out my Forester died an untimely death. The guy I sold it to rolled it :(

^^ The threads changed a lot of people's opinions on the brands they swore by and also did prove that some manufacturers did their homework and made it equal to the OEM as best they could.

It also uncovered manufacturers supplying the same filter rebranded (packaging, color etc.), many times, leaving more than one member saying I'd never use Brand X filter they're garbage, I only use Brand Y when Brand X was identical and made by Brand Y.

I do remember that! It's funny how few filter manufacturers there actually are! Gotta love re branding! It's like ring and pinion gear sets. There's only a handful of the machines that make them in the world, yet a bunch of different brands out there. They just sell them at different price ranges based on final quality, the best ones go to the "high end" sellers and the lowest quality go to the cheap sellers!

Just an update to this thread. As it turns out you can still get the Tokyo Roki filter in the U.S. Just not from Subaru.
The 2009+ Mazda RX8 uses the same spec Tokyo Roki filter that Subaru used to use. The specs are the same as the Subaru Tokyo Roki filter and they use the same Tokyo Roki part number filter.
Here's a spec sheet (credit to Boostin @lgt.com)

Those specs match the specs from Tokyo Roki for the filter they were supplying to Subaru. Mazda part number should be PN# N3R1-14-302
