No way, I still don't know what filter I need!

Nope, but I do need to stock up on some Ea046 filters before they're all gone! I'm already a preferred customer at my local AMSOIL dealer. I think he might have a few of those WIX filters left.

You know I truly need to brag here. Some time ago air filters were tested and AMSOIL came out with flying colors and here you are showing oil filters and results are not shabby. The oils have tested the same way to be high end quality.
Good signs of a company that desires to be around for a while by providing good products.

Lots of people love WIX, and for a straight cellulose filter it's at the top of its class. The construction of the WIX filters were also high quality as well. But for a little bit more money, you can get the Purolator and safely double your OCI.

Good info, thanks for sharing with us all. I've been an avid user of the OEM filter, and I figured it wouldn't perform as well as other filters costing more than double or triple the cost I get them for. I have a surplus of OEM filters to use, once those are gone I will have to base my next filter of choice by the info you shared here, thanks.

Wow good job golgo. I appreciate the work and the writeup.
Too bad the best filter of the bunch is being discontinued.
I'm a little surprised you got any information from the manufacturers besides what is already printed on the box or on their web sites. For the most part these big mfgrs are more interested in fooling people than in giving out actual fairly derived info. But then I guess you don't really know that the info they gave you is fairly derived.
I think that Toyota oil filters are pretty good. Spent a few minutes looking to see if any Toyota filters fit these cars, but I guess not.
For sure I'm not a Champion Labs fan, as you can probably tell from my closed louver photos posted a couple years ago.

Yeah, I'm going to have to track some down. I would be curious to see if apagan01 still had some. 
It wasn't easy, that's for sure. I spent weeks in some cases constantly emailing one engineer or another, often getting forwarded or passed around to someone else. With Mobil, I was able to befriend a customer support rep that was excited about my grassroots test and went the extra mile to contact the appropriate people in their engineering and marketing departments to get the correct spec sheets. DENSO not only didn't want to share their proprietary information (which everyone else has on their website in some cases and in plain view) they were pretty rude to my persistence.
That's some scary stuff right there, just goes to reinforce what I was saying that price-to-quality does matter. Not in a million years would I have ever thought to shine a flashlight down the center tube of a brand new filter. The up shot is that you have complete circumstantial evidence proving it was the filter that destroyed the motor.

the biggest point you missed stressing is ALL these filters have pressure relief valves at ~15psi. what that means is at anything over idle MOST the oil does not pass through the filter at all. the engine runs with very little of the oil being filtered at any given time. therefore NONE of these filters actually extend the life of these engines better than the next. ALL these filters allow LARGE particles to pass the filter and hurt your bearings.
mitsubishi does state the oil filtration system is full flow. but it is most certainly not. not with bypass valves set at 15psi. if you want to improve filtration get a reusable filter with no bypass.

If a filters bypass spring preload is set at 15 inch lbs this means that it takes 15 in lbs to close it shut a pond at this point the oil is routed through the filter media. When you start the car for example the oil is needed NOW to lubricate the internals so in this case the oil is routed through the bypass chambers.
Then you are asking yourself so why doesn't the filter catch the particles from bearing #1 is because when you let go of the throttle and you PSI fell under 15 lbs the oil went around the media through the bypass chambers hence the particles made it back into the oil stream. I don't care how expensive of a filter you have it will not catch it filters are not meant for this purpose.
Now we need to set the record straight on how important the filters are even in performance cars where the oil is changed very often. The filter will capture any small or large particles trying to pass through the filter itself, in the case of an EA13 filter you have the advantage that it is a synthetic media so less restriction and better filtration for longer periods a super plus from the junk paper filters. The wrong filter will allow carbon residues, and or other debris to get back into the oil flow.
