Default Mobil 1 Oil Filter

I just got a good deal at Autozone for 5 quarts of Syntec + Mobil 1 oil filter for $25.99. I've always used Purolator and Fram filters on other family cars, but i've never used Mobil 1. Are they as good or better than PureONE or Subaru OEM filters?

if your standards are low enough that a fram oil filter suits you then i have a suspicion that a m1 filter would be just fine

M1 is fine, just never use a FRAM oil filter again. Their air filters are fine, but avoid the oil at all cost.

IMO the Toyo Roki Subaru OEM filters are the best. I think the WIX filter is up there too.

I'm not too fond of M1 because I think all their stuff is overpriced.

I've heard decent things about Mobil1 oil filters. Get the special, run the oil for 4,500-5,000 miles and do a used oil analysis. It also shows oil filter performance. Look at "insolubles" on a uoa.

Having said that, I've used OEM for 65,000 miles on my FXT, 18,000 miles on a WRX and 75,000 miles on a '97 OBS. I didn't do a uoa on the OBS, but the OEM filter on the WRX and FXT were fine with oil change intervals of up to 8,000 miles.

I've used the fram oil filters for the first 80K on my car. Why are those bad again, you didn't explain why? I personally haven't found anything wrong with those filters. Since then I've been using oem filters, that I buy in bulk online. But I have nothing bad to say about the fram filters, carry on.

So have you actually done any research on why Fram is good, or did you just not look for anything? Of course for normal user that just puts the filter on and takes it off there will be no signs of good or bad performance.
Go to the sticky and read some info on oil filters.
one is here: http://www.mindspring.com/~latvia/Ot...omparison.html
Mobil 1 is fine but slightly overpriced

I believe normal users who change their oil and filters every 3k don't find much difference in the brand of filter or even oil sometimes. Those who race or have hi-po engines (including the STI engine) definitely have a responsibility to get higher quality stuff. It's all about maintaining the car no matter that you've got. And for the record, Fram has been tested to be inferior to PureOne, OEM, Bosch, Mobil 1... take your pick.

Also, what size M1 filter does a 2002 WRX use? I've heard people getting all different sizes (M1-104, 108, 110, and 112) as well as Mobil not making a filter specifically for the WRX, so it was not recommended to use it! The deal at AZ is too good to pass up.

i choose not to install it and instead used a purolator filter.

Well, you picked up the wrong filter. M108 is what goes on my family 2006 forester.
WRX uses M104 although this is not WRX specific filter and takes only about 3 turns to put on and take off.

well i'm in luck because i have an 07 fxt in the parking lot as well.
autozone's mobil 1 look up shows the m-108 for both the 07 fxt and the 02 wrx. the list the m-112 as fitting, but lists it as only availible until stock is depleted.

i still don't think i'd use it, the mobil1 filter just looks really small to my untrained eyes.

I think I'll forego the Mobil 1 filter for the rex and pick up a PureOne along the way. Still cheaper than retail altogether (and I get 2 filters ).

An engineering firm once did an in-depth comparison of all the major oil filter manufacturers. What they found out was quite interesting. I have been unable to find the link, and I'm going off memory, but Fram was the crappiest of the bunch. The research pointed out stuff like cardboard seals instead of rubber. The Fram series meets all the API and SAE standards, but those standard are low anyway.

There is a reason Jiffy lube installs these re-labeled filters with their basic oil change, THEY ARE CHEAP. As most people know, cheap is rarely good. Use what you want, but I expect, no, I demand better. I would not use Fram in a lawnmower.

yes, M108 is small because this is the application for the Forester. Pick up M104, it's the correct size for WRX.

It's not really a research firm. It's a private person that was just curious and did his own research.

M1 filters are very good quality and yield very good results in UOA (not talking about just the % solids number). I'd use Amsoil EaO oil filters first, then K&N or M1, then on down the line.

I used Fram before I did any research on filters. I liked it because it has that black paint on the outside that makes it really easy to screw off. I don't use it any more on any cars.

And yes Mobil1 is kind of expensive, but i got a good deal on it.

It's a good filter. The point about the cost is moot, because you got a good deal on it as part of the package deal. Should you buy it again instead of the OEM filter when it's time to change it? Probably not, the OEM is good and pretty reasonably priced. But in the meantime, no reason not to use it.

Crush washer is a good idea, but I use a magnetic drain plug with a regular washer and have no leaks or issues. Order the OEM filter with the washers on-line.

It's not really a research firm. It's a private person that was just curious and did his own research.
The information listed in the link you posted above is NOT the source I was quoting. I searched, briefly, the internet for the source I saw in the past, but could not find it. The topic was not important enough for me to spend a lot of time researching. I had bookmarked the website on my old laptop, but the harddrive crashed and I was unsuccessful in finding it again. I remember what the final prognosis of the study was, and that is why I use M1 filter. The same study did acknowledge that for the money, Purolator was also better than most.

Yes, M1 filters are not cheap. They are just a little bit better than Purolator, but much more expensive. For me, $12 is not a big deal, especially when you consider the cost of your investment. When I factor in all the money I waste on booze, women, and lottery tickets, the extra $6 is nothing.

At the end of the day, which filter flows the best and yet can still filter? With an 2008 STi costing me a ton of money, I would never use a Fram. K and N flows the best only 11psi drop which is good for your bearings. Prue one will filter the best hands down. This can be argued forever. By trial and error with other Japan engines costing me a ton, I have found out the hard way. Bottom line, high rpm equals K and N. Day to day equals Prue One. Cheers
