How often should I change oil filter?

If you stay awake agonizing about keeping a filter in place then change it.

Just dont try to sell it upstream as logic vs feeling.

With Honda serious fuel dilution problems I seriously can't fathom their logic?

Not stupid! That filter is probably no more than 33% used / dirty and in a large majority of cases, holds less than a half-quart.
Besides, there's more than a half-quart of old oil still in the engine at every oil change anyways. Closer to a full quart of old oil remains.
 
Change it when the the car tells you. Once, I changed mine 1/2 way through a short OCI when it told me too.

Now do you know how to LISTEN to the car?
 
Wipe your rear end every time you take a dump or every other dump?

I do not drive my vehicles with "mud butt" and change the oil filter at every oil change.

1. Honda does it
2. What about DI turbo cars that need short OCIs? Why not run a good filter for a long time instead of cheapies?
3. I read on BITOG that there was a study that claimed that leaving a little used oil in the engine was beneficial. (no citations sorry)
4. From what I understand, dirty filters although being more restrictive filter better.
5. You feel like a champ seeing the filter rust.
 
Where is the full Honda oil filter statement? My 98 Chrysler said to change filter every other time, but for normal service. Honda now uses OLM so they say run two OLM intervals? That's a lot.
Another reason I change every time is if I didn't, the oil filters I have would to be too old to use. I am not disciplined enough with shopping to restrain from buying oil filters on sale.

Sorry, but no.

Its best filtration is near the end of its lifecycle. The least efficient filtration is when its new out of the box.

Honda uses an A/B code on the OLM

OCI's are independent of FCI's

To each his own, but I change the filter at every oil change. I equate new oil and old filter with... working outside all day, then taking a shower and putting your dirty, sweaty underwear and socks back on afterwards.

Not necessarily.

Not sure the entire model line suffers from dilution or that its model based.

I can only surmise that Honda determined that fuel dilutions effect on the life of the filter medium isnt a factor.

After all its a tiny % of the sump capacity- and that tiny amount remaining in the filter and block that rediluted at the OCI for the next cycles in and of itself it is likely meaningless to filter life.

Coming from a lifetime of carbureted vehicles most have forgotten what real fuel dilution looks like.

Or maybe honda completely blew it ?

They sure did a good job on their DI system either way.

I tried this with a 2005 Pathfinder. I bought with 25K and did changed the oil ~ 6.5K and oil filter every other time...until 97K...then I went every third time and upped my interval to 7K. Used Supertech oil and a Purolator One Oil filter. Used about a 1/2 quart per oil change when I sold it at 145K. That would drop to 1,500 per 1/2 quart if I towed a trailer in CO. I live in KS.
 
The short answer: whenever you are in doubt, err on the side of caution and change the filter every time you change the oil.

Long answer: several times I have replaced the oil but kept the old oil filter on the engine for a 2nd interval. Never had a problem. ** BUT I ONLY re-used the filter in this way when it was an oil filter designed for extended oil change intervals (M1 EP, Bosch D+, etc), and the oil appeared to be very dirty before the indicated mileage interval had come. The only time I would re-use a standard filter beyond 5,000 miles is with a secondary filtration system or some other additional cleaning of the oil beyond the primary filter... because then, the filter is sharing the load and can go longer in service. This may be overthinking things a bit (as I tend to do) and not necessary, but it makes sense to me. I do get the most life/use out of my stuff without pushing it too far, and I have been maintaining and repairing my own machines for over 30 years.
 
Honda may be looking at customer happiness and shop time as much as anything. Many customers will be happy if the oil change is less money every other time, and the shop tech will save labor every other time. The engine won't be destroyed. Some of those Honda filters are in the back of the engine and are sort of a mess. Daughter had a 92 Accord and I remember that.
 
What I'm okay with is not necessarily what you or anyone else will be okay with since I have my own reasons. What I'm comfortable with, and what I currently do, is this. Spin-ons on the bottom of the engine, get replaced at every OC. With element/cartridge filters located on top, I'm ok with running a Fram Ultra or equivalent through two oil changes at 5000 OCI's.
