These filters have a greater diameter and more can volume than the TR filter. If someone opens up a spent TR, we could compare the media area.
You think the PL filter is better than the PSL? The PSL is the synthetic filter, and costs twice as much as the PL. Shouldn't the PSL be the better filter?

I don't know about cost, but the PL removes smaller particles from the oil than the PSL. If it's also cheaper, then it's a win-win. Check the efficiency specs on Purolator's site.

The PL is easy to find at most auto parts stores, but it never seems to make it to competitors' bar graphs for some reason.

I just wish it was listed as a compatible filter for our Imprezas.

On my iPhone so hopefully this shows. These are the Fram XG filters that are 20mm x 1.5. The M1-104 is 3.14" O.D. and 3.08" tall. The closest Fram Ultra equivalent would be the XG9688 or XG3593A. The ones highlighted in green will fit. Any filter wider than 3 1/4" O.D. will not.

Idk, prices still hard to find for m1-104. Only prices I can find are expensive.

It looks like the M1-401 might be discontinued.

I've been going with Napa gold filters. Curious if anyone knows if it's all that wise of a choice to go with these. I found a screaming deal so i bought 4 oil changes worth of supplies all at once.

The XG7317 is what fram says fits our cars...I was actually hoping for something bigger (taller).

A little Engine Oiling 101 for ya.

New vehicles have full flow oil systems, where 100% of the oil flows through the filter. To prevent oil starvation in the event of a clog, the bypass allows oil to continue to flow. some dirty oil is better than no oil.

general standard for engine oil pressure is ~10psi per 1000 rpm. figure at least 20psi at idle. so really anywhere over 2-3000rpm with the oem specified bypass spring rating, SOME oil will be flowing around the filter element.

with the lower psi rating spring found in some aftermarket filters, it is possible that almost all of the oil is bypassing the filter element, almost all of the time. New it may allow flow fine, but as it starts to fill up with particles.... that sounds bad to me.

Looks like the M1-108 and M1-110 fits also. Decisions decisions.

That's not how it works.

The bypass valve in the filter operates on the pressure differential between the clean and dirty side of the element.

Say at 3000 RPM, your oil pressure gauge (after the filter) measures 30 PSI.

If you install another gauge between the oil pump and filter, it may read 34 PSI, indicating a 4 PSI differential across the element. If the bypass rating on the filter is 15 PSI, it will not be letting any oil past the element, as it's only seeing a 4 PSI delta.

you're correct.

and i'd still rather have full filtration at 14 psi, than what a cheaper filter provides. it doesn't matter how good a filter element is if after a 2-3000 miles all the oil is going around it.

Hey guys, I'm a new user here and new to cars in general. I bought my first 2013 Subaru, and my first oil change is coming up. So what is the general consensus* here? Which oil filter is preferred?

edit 1: Spelling mistake

i think you mean consensus... which will be hard to find as filters, like oil, tend to be very polarizing and everyone has their own opinion.


I use Wix filters, or Napa Gold.

realistically any filter listed as compatible for your car should be OK. If you're worried about warranty, the OEM filter isn't a bad idea. But realistically if you stick to the major names you shouldn't have any problems.

the only suggestion i would make is that you get a filter with an anti-drainback valve, as it's mounted upside down.

Yes, opss. Typo from auto correct on my phone.

I'm trying my best to follow this thread and connect everything together. But it seems like as long as you replace them before they are do, it shouldn't make a difference?

are these aftermarket products being mentioned here generally better or worse then getting an OEM from the dealer?

Here's what I would do if I were you:

Go to Walmart and buy the 5-quart jugs of Pennzoil Platinum 0W-20 oil. When Walmart has this oil on sale, and when Pennzoil offers rebates on this oil, stock up.

http://www.pennzoil.com/promotions/

At the moment, all of their promotions are for having your oil changed by someone else. But they often have DIY promotions/rebates too. I can typically buy a 5-quart jug of Pennzoil Platinum at Walmart for $15 when they have a DIY promotion in effect. But even the regular $25 price for the jug isn't bad.

Then go to eBay and buy something like this:

http://www.ebay.com/itm/Fram-XG7317-...7c6688&vxp=mtr

The FRAM XG7317 is a great filter, and the $7/filter price in this auction is very good (Walmart charges something like $10 or so for this filter). So find a good multi-pack auction like this one (with free shipping), and stock up on a great filter for a good price.

Finally, buy one of these and install it during your first oil change:

http://www.amazon.com/Fumoto-F-108N-Engine-Drain-Valve/dp/B003VCB9WC/ref=sr_1_1?ie=UTF8&qid=1384952094&sr=8-1&keywords=fumoto+f-108nhttp://www.amazon.com/Fumoto-F-108N-Engine-Drain-Valve/dp/B003VCB9WC/ref=sr_1_1?ie=UTF8&qid=1384952094&sr=8-1&keywords=fumoto+f-108n


Connecting a tube to the valve's nipple makes it easy to prevent a mess. As you will see when you remove the drain plug for the first time, hot 0W-20 oil dumps out of the car FAST. This valve gives you control, prevents you from getting hot oil on your hands, makes it so that you don't have to buy a new crush washer for each oil change, and eliminates the risk of accidentally stripping the threads out of your aluminum oil pan by over-tightening the drain plug (the valve stays in place once it's installed).

Have fun!

Agree completely! All of the mentioned things are what I have done and been doing for quite a while now. I do believe walmart's price is only $9 though but either way...

L30165 - 97.5% at 20 microns, bypass is 25-35 PSI, anti-drainback valve, no PL or PSL counterpart.

Bosch 72158 - Crosses to L30165

Mann ML 1002 - Crosses to M1-104

L20073 - Same as the L30165, but with a 12-15 PSI bypass. No reason to choose this filter.

Wix 51287 - Bypass is 27-33 PSI, has an anti-drainback valve, same size as L30165, unknown efficiency.

Fram PH6941 - Crosses to L30165

PL24458 - Possibly discontinued. 99.9% at 20 microns, anti-drainback valve. Bypass is 12-15 PSI.

PL14459 - Larger than the TR part, 99.9% at 20 microns, anti-drainback valve. Bypass is 12-15 PSI. This is probably the highest efficiency option for our cars.

Mobil 1 M1-104 - Crosses to PL14459, 99.6% efficiency at 25 microns.

PL14610 - Small can, 99.9% at 20 microns, anti-drainback valve, bypass is 14-18 PSI.

PL14620 - Specs appear identical to the PL14610.

PL14612 - A shorter (possibly too short) version of the PL14610. No reason to choose this filter.


Notes:

-The PureOne (PL) parts often have Synthetic (PSL) and Classic (L) counterparts. PL outperforms PSL, which outperforms L.

-A PL30165 would be perfect for our cars, but it doesn't exist.

-The stock filter needs a high bypass pressure because it's tiny. Lower bypass pressure isn't a big concern for larger filters.

-The L30165, 51287 72158, ML 1002 and PH6941 are larger than the stock TR filter by ~0.25 quarts. The first two have known high bypass pressures, though this rating is less important for filters of this size.
these should work on a 2014 impreza right? just want to make sure.

I've run the M1-104 and PL14459. Both are excellent.

The others should work based on their specs, but data is sometimes flawed.

Stupid question... Again. I just noticed the m1-104 is smaller than the specified m1-110. Now it's said that the bigger filter will compensate the high bypass pressure. But how is that so when the 104 is the smaller one?
