Ya I thought the consensus was Wix if you can get it (don't see why you wouldn't be able to) - Napa, rockauto carry them. Wix/Napa gold is pretty similar AFAIK.
I've read enough anti-fram to stay away.

I cut one open for the hell of it. They are ok. I'm cutting a Napa gold 1515 next.

I have did this after every race on my race cars to check for any engine problems before they become to serious, filters are cheap and what get dirty anyway not the oil. The oil 8 qts. was changed each weekend of racing if there were no problems.
I also do the same with all of my cars and trucks since 1994, just a habit and I have 3 different oil filter cutters laying around anyway. With the tool it only takes about 2 min to cut open and inspect the filter to see what's up.
You need to pull the top and bottom off of the pleats and unroll the filter material to see how much is there and what all it has filtered out. That tells the tale of the tape so to say. I applaud you for at least cutting one open to see what's going on inside where some post to just shoot off there mouth without a clue about them.

Not too far from reality, I suspect.

I can imagine this scene: a nitrile gloved maniac carefully selecting a freshly removed filter. He places it on the work bench with fresh shop towels underneath it. With the deftness of 25 years experience he cuts open the filter, let's it breathe, savors the aroma of the still warm motor oil. Then, with a surgeons touch, dismantles the filter to feed his obsession.

Jesus. C'mon man. You're just being juvenile at this point. I don't know what's funnier, the fantasy scenario you just wrote, or the fact that you fantasized that scenario in your mind. LOL

FRAM ExtraGuard (Orange Can Of Death) is well documented - even recently - as to being a cheap piece of ****. The manner in which efficiencies are expressed is not very useful and does not convey any meaningful information. Even then, of the information that is given, 95% at 10 microns is pretty bad. The poster mentions specifically the nitrile anti drain-back valve hardening at 258°F. Oil temperature in a working engine that does NOT have an oil cooler (such as any 4.0L driving an AW4) will most definitely see peaks like this. I suspect this is the reason for so many ABDV failures, and noises, with this filter.
Cheap garbage.
What a horribly useless thread. Just because someone got a tour of a factory doesn't mean the product is any good. The fact that test exists imparts nothing as to level that the products are tested to. FRAM ExtraGuard (Orange Can Of Death) is well documented - even recently - as to being a cheap piece of ****.

I want all of you fram bashers to know how incredibly enjoyable it is to see how agitated you all can get. Damn.....

Well, this escalated quickly. And I didn't even post a picture of my heater control valve. 
I'd buy Wix or NAPA gold in a heartbeat, but my local Autozone doesn't carry them. Sounds like the Bosch is fine for now, and I should get rid of that STP filter ASAP. Maybe next time I drive by a NAPA I'll pop in and buy a few.

You know what's great about a CAR ENTHUSIAST forum. We get to share what we happily do to our vehicles to keep em running strong. Whether its oil, coolant, or filters, we have personal experiences with said products. So damn skippy well defend and preach what we use and yes I love when use oversized Purolator filters, I miss my oversized napa gold filters and oversized Mobil 1 filter back in the day. So south whatever your handle is, well keep preaching, that's why we are part of an ENTHUSIAST's forum.
And I must ask, what is you purpose south. You do nothing but ***** and moan about these threads. You bored and got nuttin betta to do

In my 50 years of driving, I've used a Fram oil filter from time to time and never had an issue. Just lucky so far I guess.
I'm cheap, I buy whatever name brand filter/oil is on sale at the time I need to change oil so again that means a Fram on occasion (living dangerous).
Sale priced filters don't beat the everyday price of a MotorCraft FL-1A at Walmart so that's all I have used on the XJ since I found out the FL-1A fit our '98 XJ perfectly. I'm living dangerously at the moment regarding my GMC p/u.....3 guesses and the 1st 2 don't count as to which (orange) filter was on sale. Hope it makes it.
Realistically, I think somehow it will.

Just a last thought about this topic. In the two threads that you fram bashers have been running between, I see cruiser saying that fram used to be a good filter. Yet, Freddy claims to have cut one open a long time ago (presuming before the turn of the millennium based on his 25 years of filter surgery experience) and found it to be unacceptable. Perhaps you two should huddle up and get your story straight. That's how you keep a good myth going.
