The OFFICIAL Oil Filter Testing and Results Thread (4G63T/4B11T)

Bah ! Come on what filter will run 8-9 months straight. The test you conducted was surelly a god test that showed imideate performance but not sure that it showed those intersted in the longetivity of the filter any data. for long term reliability a different test case was necessary.
The Royal Purple performed equally, as far as longetivity, that's hard to say but looking at the specs for RP it does have a higher burst pressure than the amsoil and is made in USA.

That RP filter was also the taller, skinny version. I would imagine the shorter, wide one would probably have even more media surface area. When I sent him those filters to test I didn't realize the shorter one was listed for evo x application where I was getting them.
I think that any filter over time will just end up flowing less, filtering more over time. Makes sense if you think about it. Its just gradually picking up more and more junk until its clogged. But that is why you do regular oci and run a high quality oil, and theres already a thread on that.
One point I would like to make clear before this thread starts turning into a vs debate. Any of these filters will perform fine in your car. Some of these perform better, but just like my oil analysis thread, none of those oils or none of these filters will cause your engine to fail. This testing was done to show performance difference, not to show you guys "hey if you run this filter your engine will blow", just to make it clear.

Interesting that the guy in this BITOG thread got pretty fabulous particle count results with his Bosch Distance Plus filter, whereas in golgo's test with talc and flour the particle pile was pretty average.
Some thoughts on this: 1.) Particle size, 2.) multi-pass vs first pass, and 3.) corporate shenanigans.
1.) In golgo's test there was talc, supposedely about 10 microns particle size. 10 microns is about where the particles really started to show up in the BITOG Bosch test. Bigger than 10 microns there was practically nothing.
2.) Golgo's test was essentially first-pass. In the BITOG test, the particle count indicates mostly multi-pass efficiency, because most of the particles in the test sample probably had made several trips through the oil filter.
3.) One of my favorite subjects, see post #144, and if you want to add to that, you can look down the chain (instead of up) at the suppliers and subcontractors and partners that could be involved and you've got a real mess.

What I take from these results is that the Purolator filter is just as effective as the fancy filters twice it's price, plus it's made in the USA unlike a few others. I used to run that Purolator on a WRX, maybe I should consider it for my Evo now too; at this point I've only run OEM Mitsu filters on my IX and X.

http://compare.ebay.com/like/3605910...Types&var=sbar That's the one I used, bypass valve rated at 1 bar so a little higher than the oem one was. But ya, they are great filters, but I think now with what was shown in these tests I would just run a Purolator or Royal Purple imo.

I always heard good things about the mann filters. Back in the day with my mr2 I had relocated the oil filter which allowed me to run a larger style filter. I ended up using an oem audi mann filter based on reviews about them.

The Mann filters can be had for cheap if you buy several at a time from rockauto. So I was wondering if they could be a cheap top runner filter. The Mann filters I was looking at are their over the counter ones, not the Audi ones. Also the new 100% synthetic purolator has peaked my interest and was wondering if they could be a top filter for extended intervals just like the amsoil one is. It's $10 locally which is nice too. I wouldn't do extend intervals on my Evo, but maybe on my wife's car.
