Filter changes between oil changes

I have a new '18 Tacoma. Toyota recommends 10K oil/filter change intervals. That filter is pretty small. I am wondering if changing the filter only at 5K intervals and oil as recommended (Toyota uses full synthetic in their Gen3 Tacos) is better overall for engine life.

For longer oil change intervals.

Very unlikely, if the engine is in good shape, because the filter will be nowhere near full in 10k. To be sure, check out one when it comes off. Changing the oil at 5K would be more likely to help.

Youre way over thinking this, OP! Dont waste your time/money with an early filter change. Makes no sense.

This is BITOG. Many things make no sense. You are right....but many, many on here are OCD-with oil/filter changes. Besides-do you see the many threads where the posters on here know more than the engineers that design the vehicles?

I would gather that some posters here would be more trusting of OEM maintenance intervals if engineers were writing the manuals, and not marketing people hand in hand with actuaries.

Generally, I place pretty good faith in OEM maintenance recommendations, but there are some outliers out there, and there's nothing wrong with a bit of skepticism from time to time. The old Audi called for a 12,500 km severe service interval on SJ conventional? Right.... The G37 calls for a severe service interval of 3750 miles on 5w-30 conventional, but its turbocharged replacement calls for a 10,000 mile OCI on 5w-30 conventional? Let's just say I won't be buying a used one without complete service records.

Toyota makes really good cartridge filters. Seen many used for 10k miles that look the same as it went in. I'd just run 10k OCIs on both oil and filter.

My Toyota filter that I ran used about 17.5k miles certainly looked like that, after absorbing most of the oil out of it. There was practically nothing to see in it. The Purolator I ran about 9.5k looked almost as good, except more black for some reason.
 
Depends. If it's a new style cartridge filter without the can I'd say no. When you remove the filter everyting drains into the sump. So everything gets filtered again by the new filter.

Old style can, yeah change. Toyota motor though, I doubt anything is going to be an issue for 10k. The filter is just there just in case lol

New car, do it a favor and don't wait till 10k on factory fill. Change around 1k and maybe once more at 5k if you're anal.

An engine would have to have issues to load up a filter at that mileage. I would change them both together at the specified mileage.

This. Toyota knows the holding capacity of it's filters and designs AND warrants them for 'at least' the OM recommended oci/fci. Any significant reduction in engine wear with early filter change, highly unlikely. Also a waste of resources imo.

Use the time you'd waste on early filter change to do something constructive.
 
on my 2001 1.8T jetta 200,000 at trade time while working i changed filter at 5,000 on a 10,000 change, now retired i change my filters @ 6 months on a yearly schedule running from 5 to 10 thou a year. NORIA an oil specialist noted a better filtering more important than the best oil!!!
 
A filter will likely filter more efficiently from 5k-10k miles than it did initially, from 0-5k miles. If the filter is not flow restricted from approaching or exceeding its max capacity (listed in grams, usually) then it is, in fact, filtering more efficiently.

For modern, well-maintained engines, I would argue that oil AND filter are equally important. People just assume filters can’t last as long as they can. No problem with 10k OCI’s, but 10k OFIs!? Are you out of your mind!?

I wonder if more people would be ok running their filters to 10k miles if the OEM said 20k was fine for warranty purposes.

I have never seen any technical data that says oil filters become more efficient as they load up. I have however seen technical data that says oil filters lose some efficiency as they load up, because as the delta-p increases, the trapped debris is likely to dislodge to some degree. Of course some filters behave worse than others in this regard, meaning some media can retain debris better than others because of how it's designed.
 
Do you have data on auto oil filter dP over life?

Oil, like any fluid, will tend to follow the path of least resistance. I can’t see particulates (in a practical, real-life application) being displaced from the filter media after being captured. Seems plausible, theoretically, but not realistic.

Thoughts?

It happens ... here's a bad case showing what happens as the delta-p increases. What I'm trying to convey here is that the "oil filters get more efficient with use" is a misconception. Some will behave worse than others depending on the design of the media.

There is also filter testing where the flow is fluctuated, which can also cause debris to dislodge from the media due to the fluctuating delta-P with the fluctuating oil flow. It happens ... don't believe that once a particle is captured that it's always retained. Been discussed a few times in pretty detailed threads over that last year or so.

 
Is there any correlation between particulate ejection and wear, prior to cycling through and being RE-captured by the media? Again, what is the practical detriment to running an automotive filter to 10k. I can’t think of any.

Also, a filter reaching a fully loaded condition in 70 min means the circulate is very contaminated, which isn’t consistent with actual engine oil filters. Right?
