FRAM had the WORST filtering results.....

Fram Extra Guard PH8A
This filter cartridge has a small outside diameter with a rather low filter element surface area (193 sqin), and features cardboard end caps that are glued in place. The rubber anti-drainback valve seals the rough metal backplate to the cardboard end cap and easily leaks, causing dirty oil to drain back into the pan. If you have a noisy valve train at startup, this filter is likely the cause. The bypass valves are plastic and are sometimes not molded correctly, which allows them to leak. The backplate has smaller and fewer oil inlet holes, which may restrict flow.
The telltale signs for a Fram Extra Guard are: It has 8 small holes for the oil inlet and a thin, cheap looking backplate, and is currently stamped with a "2Y". There are 5 very small crimps holding the gasket in place. If you look into the center hole all the way to the top of the filter, you will see a kind of "button" in the end cap of the cartridge (which looks like it's made of metal from there). This is the plastic bypass valve.

Like the Champ filter, this filter is made by Champion Labs. However, it uses a unique end plate and a thicker can that make it the strongest filter available for wide distribution retail sale. It also uses a synthetic media, which inproves filtration and flow. I'm happy to say that this filter is not a fake. It is definitely a unique design.
It uses a synthetic fiber element that can filter out very small particles and is very strong. It is rated just under the Purolator Pure One as far as filtering capability, but is still very much above conventional paper filters. It also has a very strong construction to withstand high pressure spikes during start-up. However, as with all Mobil 1 products, expect to pay 2 - 3 times as much for this filter.
I have received many reports of these filters failing at high pressures. It seems that the seam where the backplate crimps to the case can split.

thanks i was posting while you were and you just beat my post by a few seconds.. i can find this filter at autozone? if not what other part # mobil 1 do you recommend?

I have been using the FRAM 9688 for over a year on my Evo and have had no troubles at all with that filter. I change the oil every 3K so I think its a waste to spend a lot of money on other filters when the FRAM does the job.
My WRX had over 100K mi with FRAM oil filters and 3-4K oil changes.

i have stuck with the factory one since my days of the 2g. i had a ticking problem that was attributed to a "fram" filter. it had to do with the bypass valve. the lifters werent getting the right amount of psi, so they would tick. went back to the factory filter and the problem went away.
the factory filter is one tuff SOB...
hope that helps.

thats good for you if you had no failures-that you know of. just because people have had "no problems" doesnt mean there isnt one. i personally dont trust a filter that may not take over 110psi of oil pressure also. as the study commented on about the bypass valve failing and allowing dirty oil to pass, how do you think constant high revving 110-120psi of oil pressure is going to do to that valve that isnt sealing properly?? the oil has to go somewhere...
i usually always tear my filter apart to see the internals of the filter. i always check the bypass valve, filter element, and look for any debris.

humm... fram are 7.99 here. mobil 1 filters are like 12.99. oem filters are 5.25. and the crush ring is another .99 cents. my vote is for the oem. call me cheap... i dont care. I like oem.
Hmm.... I didn't know OEM is $5.25. I just assumed the dealer would be more money....I'll have to look into this for my next oil change.
