    Here's an interesting bit of information. Apparently the OEM filter the cars are built with in Japan (black filter, 15208AA160) are not the same as the ones available in the USA (blue filter, 15208AA15A), and many people believe the black filters are better. Subaru doesn't sell the black ones here, but someone figured out that Mazda does, under the part number N3R1-14-302. They say it is exactly the same filter in every particular except that it says Mazda instead of Subaru on it. I don't have personal experience with it but a lot of people seem to be having good results. Take it for what it's worth to you.

    If you talk to people in most R&D departmernts, you'll find that they are some bright people in there that know almost everything about anything they have worked on. The problem is once the design leaves the R&D department and goes into manufacturing, the process of cutting the raw cost to build the product starts. They start tinkering with the R&D departments design (with some level of consultation mind you) in order to increase the repeatability of the design in manufacturing as well as reduce the cost so that the product can meet the desired price point while keeping reasonable reliability. When that starts to happen, they start making compromises with the original design resulting in something that more aligns to the goals of the product as well as the price point desired. Some of those changes are good for the consumer while others is not so much.

    We, as consumers, like to think that those goals are aligned with our goals but sometimes they aren't.
    x2 all day long and then some.

    A lot of what leaves the factory isn't what the engineers wanted in the design.


    As far as Fram filters, I wouldn't touch one of their low end filters unless I had no other choice. Their "composite" (read: cardboard) end caps may not have a failure rate that causes problems but why take the risk? On the other hand, their top end filter is pretty well made and a quality product.

    But when it comes to keeping my engine alive for the duration there is no reason not to spend a couple extra dollars per oil change on the top end filters. With modern oil change intervals going up, you can only benefit from the better designed filters. So you spend an extra $10 a year on your oil changes. Big deal. It's worth it to have the peace of mind that you won't have a catastrophic failure because you saved a couple of bucks on a cheap oil filter.

    I remember seeing Mahle oil filters online at NAPA, but they were around $12 each at the time. I trust NAPA Auto Parts, so if they sell Mahle it should be a good filter.

    Just make sure the the oil filter meets Subaru's by-pass relief requirements. If I remember correctly it should be at least 26 lb. by-pass relief. Very important spec to meet.

    The black filters are a better-built filter - people who have cut those two filters in half have verified it as such. Having said that, we don't know if it actually needs to be that well built... the car may not utilize the higher built quality of the black filters. We have not had a report where the blue filters have failed in service which is a testament to the blue filters and the level of quality required.

    Bypass is not at all important IMHO The oil filter's bypass will actuate just before the filter gets clogged (which is very unlikely to happen) .
    What is the efficiency of the Mahle. I'm just kidding..its unknown. Most likely 95% at 40 microns where the Fram Ultra is 99% at 20 microns.

    You can't say something is unknown, and then guess at it just to try and make your point. I'm fairly confident that you will never be able to convince anyone to have the same faith in Fram as you seem to. It doesn't even matter if they have a better filter these days, they are limited by their brand name. Their reputation. And again, go watch some videos about Fram filters, but just like you won't convince me I'm sure there is nothing that will change your mind, either.

    I'd also take an OEM Mahle filter over a Fram, any day.

    Since we're on the topic of oil filters.. I've never had a top-mounted filter car before.. how much of a mess is doing an oil change? Is most of the oil drained out of the filter via the drain plug by the time you get around to removing the filter? My sales guy implied that the Subaru filter had a ball **** type of thing in it to stop the oil from leaking out of the filter.. but that doesn't seem accurate? No aftermarket filter would have that if it were true.

    I just looked at a blue Subaru filter for my 2018 Forester which has a top-mounted filter. I don't see anything like a ball inside. Sales people! When changing oil with a top-mounted filter most of the oil drains out before loosening it. Last time I changed my oil filter the little bit of oil left behind in the filter's "catch pan" was wiped clean with a single kleenex tissue.

    The oil is draind out of the filter a minute after you shut off the engine. Simple as pie to change it. Its brilliant. All filters drain..the anti drainback valve has no effect when the filter is upside down. Brilliant on Subaru's part. They are the most innovative car company IMHO...opposed 4 engine, symetrical AWD, pioneered safety since 1960.

    You bill yourself as a "Lubrication/Maintenance engineer" but say the bypass pressure of a filter is not important? This forum is a civil place, so I will just kindly suggest you rethink your position on that. Would you run a filter with a 1 pound bypass on your Subaru? Or one with a 100lb? I'm hoping you answer no to both of those.
