how do i know when the oil filter's clogged? my OCIs are 8k and i was thinking about leaving my pureone on and running it for another OCI (16k miles total). is there any way to know when the oil filter goes into bypass mode?
when to change oil filter?

If I'm crawling under the car, the filter's coming off when the oil comes out.
i cant tell you about knowing when its in by pass mode or not, but theres no way i would let a filter stay on for that long. especially if the oils getting chagned in between anyways, and especially if its in a nice (in my opinion) 02 mustang gt
Change the oil, change the filter. End of statement. Period.
ditto. I almost think that you're messin with us....
Not sure if they still do, but at one time the SOP with Hondas was to change the filter every other oil change. I don't recall a bunch of Hondas dying prematurely from it.
Do you take a shower and put on dirty underwear?
Like others have said, you're already under there so go ahead and change it. However I feel compelled to ask, why don't you want to change your filter? Is it very difficult to get to? Do you want to save a few bucks? Are you trying to make your oil changes easier/faster?
I personally wouldn't use a filter for 16k miles, but that's just me. Plus my filters are VERY easily accessible (don't even need to raise the car), they're perfectly vertical so they don't make much of a mess, and I'm able to get PureOnes for under $3 each after rebate. So I don't think twice about changing it every time.
Let us know why you don't want to change yours and we'll be able to better address this matter

New oil filter = cheap engine insurance
Filtration increases with mileage, and thus leaving a filter on for more than one oil change should be no problem. Just do some used oil analysis to find out the mileage, time or Hour limit of the filter. Changing the filter is a pain and very messy on and engine. I'm a fan of 2 oci's per filter.

Sounds like K&N logic!

Very simple. With use, the bigger pores eventually catch something big enough to block them. The longer you run a filter, the more already collected particles the oil has to pass through thus the odds of collecting more particles. The in depth media doesn't work like a sieve.
So efficiency goes up and flow down the longer you run it. What we have very little to go on is is how a filter is flowing after 3K.

ok guys no this isn't a joke my reasoning for doing this is exactly what oliveoil said. it's a fact that filters gain more efficiency over time. this is true for both air filters AND oil filters. as more and more particles become trapped in the filter, the space for other harmful particles to squeeze through is decreased. think of it as a dirt shield over the original filter. in fact a filter will filter best right before it becomes clogged. so in other words, if you're trashing the oil filter before its time, you're not even using it to its full potential.
and on a smaller note i'm also trying to cut down on the amount of waste i throw out which is why i use extended OCIs and filters.
EDIT: well labman beat me to the explanation (and he explained it better than i did), but my point still stands

The question is, is this extra efficiency really required? And is it worth it at the expense of decreased flow?
If particles can go through the filter media, it means they're small enough to not do any harm. Maybe it is not at all necessary for a higher efficiency filter to trap them.
Just playing devil's advocate here....

Good points Pete. I wish we had some real data to base our decisions on. River Rat gave us a start, but a long way to go. Maybe Frams secret is skimpy media and let it quickly become highly efficient.

I couldn't have said so better myself. The 8000 mile OCI the OP uses is plenty for a Pure One filter. Change the filter with the oil.
While efficiency might increase with filter life, 16,000 miles is a long time. Then don't forget the 1/2 qt or more of dirty oil the old filter has laying inside of it just waiting to get mixed into the fresh oil. I'll pass and spend a few $$ more on a new filter.

I'm not sure I'd call it SOP. While Honda does/did recommend this practice (10k oil/20k filter in our '06 CR-V for normal), I've never seen a dealer or quick-change place follow it...don't know any DIY Honda owners who do it either.
