K&N and Mobil 1 Oil Filter change interval?

I will bet you can go 7500-10,000 on any of the filters mentioned with no ill effects using a synthetic or Schaeffers blend. The oil does the work not the filters for 99% effort, IMO.
It all depends on your engine, its condition, driving style, type of miles, and oil used. the Pure One is nearly as effeicent as the Mobil1 and the K&N is more like the others in efficiency, just heavy duty.

It is so hard to pin down an exact number because even two engines of the same type might put out different wear metals depending on the person's driving style. I personally don't think filters are clogging up as fast as 3000 miles though, but I do believe the PureONE will clog up faster than most.
I am pretty sure the K&N would last quite a bit longer than the Mobil 1 before it fills up, simply because it doesn't filter down as small.
One area of concern is also with those filters that are horizontal and really need the antidrainback valves the most. If a filter is left on for a longer time period that antidrainback function might not be as effective anymore.
My plan with the cars in my "test fleet" is this. I will run the K&N filter on my 95 LT1 Firebird as high as 12k (the thing is HUGE!) and the filter on my wife's Honda (a 2000 Civic) should be good to about 9k. On my mom's car (94 Probe GT) I just installed fresh oil and a PureONE and will go one full year which should only be about 7 or 8k at most. I may change her filter partway through, depending on how her oil analysis results look ( I am sending them off this morning) On my sister's car (99 Civic) I'm going to be running an AC Delco filter, and I figure it should be good for 9-12k, especially since it is only really a 25-30 micron filter so it shouldn't fill up all that fast.

Patman, do have K&N's filter number for GM's oil filters p-35 or P-1218? I have an LT1 and like those biggins'.

Carl, the one I use on my LT1 is the HP3002, which is a direct cross reference to the PF1218.

I'm sorry but I don't know what the long filters are for these. Have you tried asking on the Corral to see if one of the 4.6 Mustang guys know?

When you find out, post it here, as I have a good friend in NJ who has a 97 Cobra convertible (in rare Pacific Green) who would probably want to go with the longer filter on his too.
Patman, Metro, Baldwin's catalog shows these specs for the Ford filter. Might help xref with other brands?

Metro, I was thinking of the specs, not the models. Maybe visit a store with catalogs, or con Patan into looking up an unofficial Purolator match. (They list size/threads/bypass/etc.) From there you can cross to other brands.

When I get home I will look up in the Purolator catalog to see what I can come up with there.

This is the only thing I can find in the Purolator catalog with an M22x1.5 connection and an 8-10psi bypass, it's the L24484, it's 3.15x4.01 in size. Anything else with that connection size has a vastly different bypass setting.
Actually if you have a 8 psi bypass, I would not be afraid going with an 11-14 psi on a larger filter. I have seen these values interchangable on different stock replacement filters. Again-only an opinion. You'll have to decide.
Thanks! Happy Holidays!!
