This is pretty funny, really, and your prediction on post #1 is probably right about NEPRT-hood. But...
If one were to attempt to apply some logic, they might infer that a longer filter would have more filter media ( which is not necessarily true when dealing with varying manufacturers), and that having more filter media surface area would be an asset if/when they ran the oil filter long enough that the media was becoming partially clogged with filtered particulates.
But... how many of you anal retentive SOBs (I include myself in this subset, BTW) actually follow the owner and service manual's recommendation to only change the filter every other oil change? If not, then having a bigger filter is clearly a moot point.
I mean... when was the last time you heard of someone lunching their engine due to oil starvation?
BTW - The gen 1 oil filters are the superior choice. JSaNS
