What does price have to due with the efficiency and functionality of a oil filter?

Absolutely.

Would you trust an E-Core (or similar piece of junk) for more than 7500 miles? I wouldn't. Lots of folks that don't give a hoot abou their vehicles certainly do.

My supervisor used to go 7,000-15,000 miles on PYB and Fram filters in her Nissan Sentra. It had 250,000 miles on it before she got rid of it.

I assume you think your supervisor didn't give a hoot about her vehicle. But where in her 250,000 miles of ownership did her maintenance practice fail?

And Dnewton is proving that those intervals aren't beyond the oils and filters capabilities.
In fact he is using supertech but I cannot recall which filter. He is running 15000 mile intervals just to prove that those intervals will NOT perceptibly shorten the lifespan of an engine.
Talk about putting you money where your mouth is. He is using his personal vehicle as the test mule and doing a uoa after each run. Then he posts them and we are all flabbergasted that supertech oil can protect an engine at that interval,and the oil filter didn't explode.
So in all honesty I will bet that the sentra in question went on to live many more hundreds of thousands of miles and I bet it ran just fine as the body rusted off around the engine.
Face it. None of us truly push our oil change intervals other than a select few here. We all throw money away with 5000 mile oci on a quality syn,and we pay big bucks on filters we throw away before even 1/4 of its useful life has expired.
And we do it for "peace of mind" because we actually convinced ourselves that in doing so our motors will last longer in the end. And you know what the engines are likely pristine and you could drive them own to the crusher instead of burning diesel in the heavy equipment to put them in there.
My point is that over the long haul those of us who spent more on maintenance never see a return on that money. No one pays more for a used car that used synthetic oil every oil change and the possibility exists that you could have an engine with 200k on it and it runs like brand new,until that dumb dumb blows the red light and t-bones ya.
You can agree,or disagree,it make no difference to me however anyone with some sense can read what I just wrote and see that I'm right.
And just to be clear I am one of you,the over obsessor changing my oil too early however I am leaving my filters on for longer now.
Just wanted to clarify so no one assumes I'm taking any shots at anyone

have run P1 for 22k miles and 23 months and it was spotless when i cut it open.

on the other hand if its not clean to start with thats another story

see for yourself

If Honda can confidently say to use your filters for two oil changes, you can be comfortable running it for 10k miles. I changed them on my Hondas every other oil change and many others on this site have done it on many models with no damage. As noted above, the filters filter even better as the bigger holes get clogged up.



x2. The New Civic's Maintenance Minder does in fact recommend that you run the Honda oil filter for 2x intervals. Based on your driving style, those intervals can be anywhere from 6,000 - 10,000 miles x2. Obviously they know that the filter will be fine.

I personally use Mobil 1 oil filters for their full rating of 15,000 miles. In my 07 Civic, that was 2x 7,500 mile oil change intervals.

Honda only calls for an oil filter replacement with every "B" service, which is every other oil change.

Of course, the recommendation was made with the assumption that you are using an OE grade filter, so it would not wise to attempt this maintenance schedule while using an entry-level Proselect or Purolator classic filter.

I use M1 0w20 and usually OE filters (though I used a Fram ultra last time) on my friend's 2012 Civic. On her car, the intervals are about 11k per the Maint Minder.

IMO, yes. I would be more concerned with time rather than miles. I dont know how long the filter media would last before beginning to break down (all you would need is a small rip to make it useless) but I would guess at least a couple of years.

I am interested to understand why a Purolator Classic would be considered inferior to an OEM filter.

nothing I suppose. Im looking at intervals and functionality, not price as the driving factor. I change my oil every 5k using tropartic and usually bosh or mann filters. 10k miles on one filter would make me a little nervous.

I guess if I really knew how much my filters were filling up, how much capacity etc, I would feel better but I don't. So for 3 bucks I put on a new filter. If I was unsure and filters were $15, I would still change it. As it is, its a no brainer to me.

Honda has been doing this for a very long time. Even our 94 Integra which had 7500 mile oil change intervals, only recommended replacing the filter every other oil change! Cars like my whole for sob have a two year and up to 15,000 mile will change interval. No problem.

Remember the filtration is based upon building up the cake, and so you want to have a good number of particles trapped in the media in order to get optimize filtration. New filter to not work as well as filters that have some contaminants entrapped in them already. You're really balancing filtration efficiency against the pressure drop and flowrate through the media.

The only consideration then is either breakdown of the media or breakdown of the adhesives, both of which have proven themselves significantly for durations far longer than two years or 7500 or 15,000 miles!

So when a filter says 98% multipass efficiency for 15 micron size particle for instance, is it getting that from the start or is that after some of the "cake" build up?

Also, I was looking on the Purolator website awhile back, they recommend 3k change intervals on one of their filters, I believe the classic. Is that a marketing thing to get us to buy more or is there some science to it? Even a bosch distance plus is only recommended to 10k I think.

I honestly thought somewhere between 5-7k was a good interval for a filter, maybe even pushing it a little considering some recommendations.

I put both of my work vehicles through [censored] and back running 5-7k intervals with oil and filter being changed every time. I just cant see a reason to push it to 10k plus. Still seems unnecessary regardless of efficiency when the filters are so cheap.

Here's a question: If a filter has a better flow rate will the engine be better protected during start ups? I know Mobil 1 filters claim this...

^ flow rate is negligible at startup, due to the ADBV. If cold oil can't get through the media, the ADBV will momentarily open to allow oil to flow.
