not all oils are equal in quality, same goes for oil filters. personally, i won't be using fram filters again. they use carboard ends in the filter that are prone to failure.
i've have never personally suffered from a oil filter leaking and i only hand tighten em, i oil the seal (i remove it from the filter and cover the entire rubber seal) but i certainly require a filter wrench to get em off. over hte years i've used ryco, valvoline and fram
with regards to longer oil change intervals, increased sump capacity is part of the answer, so is increased oil quality and so is engine design. another great influence would be the operating conditions of the engine/vehicle another greatly overlooked issue is that oil companies would like you to change the the oil on a more regular basis (how often do you change your oil and what is the reason for that oil change, maybe because thats what your dad did?), engine manufactureres test there engines with what ever they specify and say that the oil is good for X Km's, however, how do you know that the oil is actually bad before you change it. personaly i don't mind changing the oil on a more regular basis as i get it cheap. oil testing is a good solution, however until it's cheaper to test oil then it is to drain and replace the oil i don't see that happening.
just to throw another issue into the mix, did you know that during a cold start, a good portion of the oil bypasses the oil filter and goes straight to the engine. when a engine sits, any particle contamination present in the oil will tend to settle at the bottom of the sump, so on a cold start, this is the oil that the pick-up gets first, doesn't go through the filter and goes straight to your bearings.........
just a note of interest, back in the day, brockies race cars ran a remote, twin filter setup. a race car that gets clean oil after every race meet, if not after every race, yet they wanted maximum oil filtration
