I know the general opinion of the K&N air filter around here, but has anyone used a K&N oil filter or know of any reasons not to use one. If they don't really do a better job than the oem I think I'll just save the $6 and stick with the oem filter.
It's not just "around here." The K&N is probably OK for on-road applications. Off-road is where the problems come in and the opinion is pretty wide-spread. Do a Google if you are interested. There are several real-world tests done by the Aussies and the K&N does very poorly in comparisons.

I used them in both Ford power strokes that I have had and never had any problems. Of course they never left the pavement as they were used for long distance travel. I had one on my '94 Toy DLX PU but once again, I was commuting from Vancouver WA to Los Angeles every weekend when I put it on. I do not doubt that they might pass dirt while off-roading. I was a little skeptical when I read that they were supposed to be more efficient as they got dirtier. I will be sticking with the oem air filters for my '96 LC. But how about the K&N OIL filter?
K&N oil filters are made by champoin labs, CL makes a lot of filters from Mobil one to walmart supertech all of them used to be good unil they came out with thier POS E-core on the cheaper lines.
AFIK the K&N's are still well made, generally considered to have good flow but maybe not the best filtration but acceptable.
I don't think anyone could make a definitive statement about oilfilters unless they ran identical trucks with brand A versus brand B. Even then unless on a large scale test of thousands of vehicles with high mileage could you begin to notice a trend of failure in certain components. I just took a pansy OEM filter that was the size of a coke can and replaced it with a Napa premium grade that was the size of a Fosters beer can. Is it better? Probably not. But it's bigger and I'll never know.
I get your point, but I wouldn't go that far. Plenty of people have sawed various brands of filters in half and have found pretty obvious differences in manufacturing quality (ie, FRAM) and also filtering and/or flow quality.
Back to your point though, the question is still how much those differences actually matter in the long run.

well yes and no, you cannot say if you run brand "B" your motor will push a rod out the side of the block in 61,358 miles but an oil filter is not that complicated, you can take the wide amount of data available and see what are well made filters that will do what you want,
For instance all you need to do is cut open a Fram filter to see the poor construction quality both in general and in the active ingredient of a filter: the filter media, cheap construction and not so cheap price makes a poor value.
Using the pore size and flow numbers linked above you can select a filter that gives both a reasonable price good flow and good filtration; I wish the Toyota filters were included in that study as I suspect they would do well
