High mileage oil filters - worth the extra cost?

I found a lot (actually an amazing amount ..) of good info on oil on this site, but couldn't find anything on high-mileage oil filters. I used Fram on my '05 (mainly because of the grip coating) but could only find their high-mileage version for my "new" car - which has 164,000 km on it.

If I recall, Fram was recommending this filter for engines over 120,000 km, but the price is beteen 2x and 3x that of a "regular" filter - so am wondering if it is worth the extra $$? I don't want to appear cheap but like to get value.

Too early to comment on oil consumption so just put in regular 5W30 dino.

Edit - I came across this article yesterday which may be of interest

My preliminary conclusion is to stick with a good brand of regular filter.

I can't provide a definite answer for you but I will offer what I do know. I believe the primary thing to look for is first pass filtering efficiency. There used to be only a few brands of premium oil filters made but now there are many major brands of premium filters. I would just look to use the cheapest one that has a first pass efficiency on the ~96% range. Paying too much for premium items like this is generally a money waster.

Oil Filters Revealed - MiniMopar Resources

My preliminary conclusion is to stick with a good brand of regular filter.
The FRAM High Mileage filter is just a sales gimmick. They are trying to get a piece of the high mileage marketing craze. These are "FRAM ExtraGuard" filters with a drop of goo in the middle. I wouldn't trust that goo in my engine and I'd be concerned how it is effecting flow in the filter. In my opinion you don't need this, but to each his own.

If you really want to be picky about oil filters then I'd suggest just buying the Subaru OEM oil filter for your car. You can pick them up between $5-$7.

If you want a better approach to this 'high mileage' thing then just use a "high mileage" oil. High Mileage oils come in straight conventional or conventional/synthetic blend. Both have a higher concentration of detergents to clean your engine and added conditioners to revive seals versus regular conventional oil.

That being said, I got 450,000 miles out of my last Subaru on nothing but regular conventional oil. I used a mix of OEM and regular aftermarket oil filters through the years. It could have kept going, but I got into an accident. RIP Sooby!

That's a 10 year old study. Use whatever filter you want. If that recommendation is real its bs.

Be careful what you wish for.

I wouldn't pay anything extra for any fram product, they're just not very good compared to most of the competition.

Just go with any good standard filter. Don't pay extra for the fancy ones like K&N or mobil1 (for our cars the mobil1 has the smallest amount of filter material of any filter). I like purolator (although i'm not a big fan of the newer gold pureones), wix/napa, tokyo roki (the 09+ mazda rx8 factory filter is a tokyo roki with the correct specs for our cars), or possibly the blue factory filters (made by the same people as fram, but decent quality and a pretty good gasket design)

I like the ACDelco ones ( I think that's what they are) got them at Farm & Fleet. I try to stay away from fram, heard bad things about their filters coming apart and clogging engines.

AC Delco filters are made by Champ. While the AC Delco filters can certainly be cross-referenced to other cars they are specific to GM vehicles. Champ's new filters are the e-core design. That means the center-tube is made of nylon. I've seen several that have collapsed causing weak-points in the media followed by complete filter failure. The felt endcaps are poorly bonded to the filter element and for the life of me I can't imagine why they decided to put them on at all. They're so weak that they can't possible serve any real purpose. To me it looks like a far weaker design than FRAM ExtraGuard. I've seen a lot of media failures with these on bitog. http://www.bobistheoilguy.com/forums...Number=2099058

FRAM really isn't a bad filter. Their multi-pass efficiency ratings are fine and their endcaps are made of condensed filter media that is bonded ridiculously well to the filter element. I don't see what all the negative fuss is about.

The negative fuss is the number of Fram filters that have mechanically failed (split, clogged, etc). Not just internet legend, I've had people I know have Fram filter problems. I won't buy 'em. They are built to a price so K-mart, Wally World etc will sell them. I buy NAPA or Wix filters by the case and the price is very competitive if you shop around or ask your vendor for a 'deal'.

I don't believe it matters much beyond that what kind of oil or filter you use if you are changing it frequently. That's more important than the actual product used.

Fram's top of the line filter is good, but expensive. Their base model and mid-level are overpriced in my opinion.

I'm currently running PureOne's in my Outback, and they seem to be doing fine for my 4-6k OCI.

Been using Fram filters almost exclusively since I started driving (22 years ago ). Only time I've had non-Fram is when it's dealer installed or thye parts stores didn't have one for my car. Never had anything even close to a failure.

Well, we all have our opinions on one filter or another. The Subaru 15208AA12A OEMs have worked great for me. My Honda also has oil filters built by Honeywell. No problems.

Here's some pictures of a Subaru OEM oil filter I cut open some time ago after 4,000+ mile oil change interval. It's simply a FRAM PH9715 ExtraGaurd with an upgraded gasket and higher pressure bypass relief valve. In case anyone is wondering I use Chevron Supreme Conventional 5W-30, it's a 2008 2.5x Forester, and at the time it had 57,000 miles.

Yup. It was my 1995 Legacy L AWD 5-speed. It had the 2.2L engine. Best car I've ever owned and probably ever will own. Everything worked all the way to the end. Power windows, A/C, everything.

This is a picture of it after a big snow storm in Colorado. At this time it had around 420,000 miles on it.

Don't forget that air filters also effect oil cleanliness, or lack thereof. There are more factors than just the oil filter (kudos to the dude who posted filter pictures, real evidence beats heresay 100% of the time).
