Chrysler and Honda, and even VW, IIRC, were all recommending oil filter changes at 15k miles (every other 7.5k mile) intervals back in the 90's. Nothing new here. I've left oil filters on for years with no issues.
Yes, the trend by some of the car manufacturers has been to down size the oil filter. Newer cleaner running engines along with the good oil of today (and regular sceduled maintenance) don't generate debris like the older engines did. So the oil filter can be down sized some to match the recommended OCI.Another thing to factor into this whole equation, is oil filter size. In the 70's, 80's and even well into the 90's, full size oil filters were the norm on most all engines. My 1991 Ford 5.0 uses the full size Motorcraft FL-1A, (PH-8A Fram). Today you have these tiny mini filters everywhere. The oil filter on my 2018 Camry is the same size that's used on the V twin Briggs & Stratton Vanguard, and several motorcycles. (My 1984 V-65 Magna Honda had a bigger filter)..... And a much shorter OCI.
I doubt all of these tiny filters have half the filtering media that a PH-8A full size oil filter does..... And now they're telling you to leave it on twice as long?? For what? What's the upside of doing this? Saving $5.00, and the 5 minutes it takes to change it out twice a year? That's not enough of an incentive for me. In fact, it's no incentive at all.
That's why a lot of guys here go up a grade or two in viscosity and do shorter OCIs than what the manual calls out. More tailoring beyond the manual recomedations if people want to.Another thing is, today all of these engineers are being pushed by their companies, to conform to meet and exceed CAFE mileage requirements. And A LOT of things are going wrong because of it. Toyota now has engines that are plagued with seizing piston rings, that are gouging into cylinder walls. And Honda is having massive fuel / oil dilution problems, that have brought about several class action law suits, to name just two.
Toyota has said more frequent oil changes can help eliminate this. (See above video).... And Honda SHOULD BE SAYING IT. I can't think of anything much worse for a modern engine, than introducing gasoline into these already water thin oils they're using. All in an attempt to squeeze out every last fraction of MPG. This is all becoming a big Catch 22, as to what NOT to do, in order to keep your engine alive longer.
I just can’t it’s too natural to change out the filter each oil change. If anything you’re short changing the oil.
Just figuratively speaking.. a premium filter meant to run 10k should be used with synthetic oil that in most cases unless direct injection can go the same haul as the filter. So what’s the moral of this story you wanting to save yourself the hassle and extra expense of swapping out a filter each oil change.
So go ahead just leave it in place for two oil changes or if you’re not dealing with direct injection just run full synthetic and your premium filter to 10k
Wasn't looking to offend you I used the word "figuratively"... ill cut it short just run a longer oil change interval. You'll save on half used oil.Why would the filter care what oil is being run through it? Are you contending the fuel in the oil damages the filter somehow?
What about filters designed and rated to run to 20K? Mobil 1, Fram Ultra / titanium, Wix XP/ Napa platinum, Amsoil...or 15K like the boss.
Have you let these guys know they have it wrong?..... you could write a letter (very strongly worded)
What I dont like doing is throwing away half used products for no reason, If I had ANY evidence that the filter manufacturers, or auto maker had this wrong, or I saw any evidence in the filters I cut open (I cut every one), or in the UOA's - I wouldn't do it.
zero offense, just a bunch of guys chatting. Digital campfire so to speak.Wasn't looking to offend you I used the word "figuratively"... ill cut it short just run a longer oil change interval. You'll save on half used oil.
Do Honda dealers leave the filter on one more time? I don't think they do for the most part. Besides, like all dealers they want to add conditioner and snake oil to pad the profit while they have you on the hook.
This is what I started doing for my vehicles with Fram Ultras.I'm tempted to break old habit and start using for 2 OCI's. But if I do it'll because I'm changing oil at 5k intervals on something rated for 10k OCI's.
Trying to understand, your oil filters capture no particles, or just don’t see the ones the eye can’t see? Just on a I don’t know about that basis I couldn’t leave a used filter on two three oil changes. Maybe I see it as I just want to get all the particles away as much as I can. Besides I buy too many filters and need to use them.On triple use, Ive been doing that for about 60K in my titan.
I'll change oil in my truck at about 6-7K and keep the filter on for 3, just shy of 20K or very slightly over.
I've yet to see anything in the pleats (no carbon chunk- nothing), but the wall where the mag is has had plenty of crud on it.
The thin wall of the ultra that makes it a downside if exposed offeroad, lets it work better with a mag.
As long as that crud isnt going through my timing chain and bearings Im a happier guy

You guys trash talking and doing laugh faces have made zero technical points … my newest vehicle allows 9k on an average filter … 10k on a Fram Ultra is an easy run …
