Oil Filter every 10,000 miles is overkill?

If I could get a H badged diesel wagon with a manual.. I wouldn't be registered on this forum. :p

I also am in the camp of "I will change the filter if my masters tell me." And if able to get one. But that doesn't mean its doing anything useful necessarily. Looks like it is likely not doing anything useful based on some of the feedback in the thread.

I have had cars that burned enough oil to be perpetually full of new oil. Zero of those were Hondas though..

There are just too many to list....
As someone who has taken a Mazda B2000 pickup past 400k miles, I know about "burned enough oil to be perpetually full of new oil" :D It didn't actually get a conventional oil change for the last ~70k miles of its life. And was still running perfectly fine when I smashed into a deer.

Disagree with the “inexpensive” part. My Honda doesn’t have a fuel filter replacement every 20,000. Or $1300 timing belt replacement. Tires are only $70 each and oil just 3 quarts
Timing belts cost $1300? Last I checked, everyone sold them for around $300. Well, okay, maybe closer to $400 when you factor in an oil change and some G13 coolant, but $1300? remind me to stay away from your source for parts!

*To have a dealer replace, I think that is close to the cost. Never had a dealer do that work on any of mine but it's spendy, even at 100-120k mile intervals. All I know is that regular and timely maintenance (and some car washes) will keep these things on the road for many many happy miles in my experience. We have a 300 and 200k TDI in our little fleet and a nice MK7 GSP TDI with just 80k, I love my TDI's and VW for all their weird and some times annoying quirks has treated my family well. :)

98 Jetta TDI AHU 1.9L (944 TDI swap in progress) I moved so now i got nothing but an AHU in a garage on a pallet.
FWIW, i have always changed the filter with the oil and usually let it go fairly far, the TDI got 14k between changes, the escape i do about 10k (supposed to be 7.5k, and all my other cars usually whenever, but never get to far past service.
never once had i have a failure or have i heard of a failure being from going a bit past oil changes other than in sub 0 temp areas. old oil just wont move.

the chances of something else taking out the engine are way higher than it just getting old and failing because you didn't change the oil properly. (USUALLY)

I didn't think about that, but I won't let the stealership touch my cars. I made that mistake once for my CPO warranty, and decided to void it by pulling the emissions crap (a lot of it myself). Changing the timing belt on a CJAA is honestly very easy. I still can't get over $900 of labor - it's not even an 9 hour feat!

You don't have to add oil between changes? On everything, I usually gotta add some oil by the 5K mark.

oh yea, definitely. usually because the repair is more $ than the oil im going to burn and or i live to accept it. my escape will use about 2 quarts over 10K, the TDI used very little, about 1/4 to half a quart in 14K. my SBC van, LOL that beast never lost a drop in its life but 4k oil changes because well, 1985 was a good year for SBC engines! even with 230K on the clock.
worst offender is my nighthawk, 3k oil changes, eats about 2 quarts between changes, only a 3 quart system. needless to say that engine is being rebuilt right now. turns out it has stuck oil rings. this is why i hate air / oil cooled engines that rev to 11,000 RPMs

I don't think I really like any aircooled engines. I've been toying with selling my Yanmar 2kw diesel generator as a result. It's nice to have, but who the hell survives on only 2kw?

Bad air cooled motors are bad because they are bad, not because they are aircooled. Maybe I'm just old but IMHO plenty of excellent ones. How many miles were on that nighthawk? Not really familiar with those.

I said air cooled (the night hawk has an oil cooler too) engines that rev to the moon. governor cutoff is 9500 and i drove it that way most of the time.
most reliable engines are air cooled IMO specially 2 strokes.

Right, the 1st sentence was meant for pkhoury. Last part was for you.. I have had a few air cooled bikes too. Guessing dohc "cb750" right? I am more familiar with the single cam ones.

I have skipped filters a few times in my life because I couldn't find a filter. Kind of bugged me at the times it happened, but now that I read this thread.. Well it won't bother me the next time it happens.

Ive said it before and been flamed for it, but it's been my habit on most of my TDIs to change the filter every other oil change (which I stick close to the 10k mile interval). My reasoning doesn't have much to do with cost, it's minimal. I run DelVac 1 5w-40 which many/all that test have had great UOA even at 20k miles. I don't put many miles on my TDIs anymore since I don't work commute anymore and have a "winter" and non-salt Jettas and several other vehicles.
The filters I have dissected/inspected don't have anything in them, no signs of particles or clogging, even after "double" miles. The same filters run as long/longer in extended change intervals and in the cars that have the oil monitoring system. I haven't damaged one yet...

I do drive more than 50,000 miles a year! I do an oil change every 8 to 9 weeks.

I wouldn't call my air cooled motor bad, by any means. I hear Yanmar motors are reknowned for longevity. My complaint is that in its application, it's somewhat useless.

I know the feeling. Even with COVID last year, I still managed to rack up around 55,000 miles all year.

I guess skipping oil filter changes saves a lot of money and gives a great deal of satisfaction.
The oil flows at maybe at a rate the exchanges the oil in about two minutes or less so there is a good bit of flow and the question would be what is the differential pressure at that flow?
Oil filters have bypass valves that open when some differential pressure is reached.
The resistance to flow is due to those small particles being trapped in the maze that makes up the fabric of the filter.
I have had an O ring blow out on one of the old Rabbit Diesels when cold due to the lack of a relief valve in the block and a poor design by Delco.
It doesn't take particles that you can see to fill the voids in the fabric. As a matter of fact as the smaller voids and the intricate maze of fibers are filled the filter becomes less able to trap some of those particles.
That being said in some cased (particularly in air filters where the trapped debris is usually fibrous) the filtering could be improved at cost of higher back pressure
That higher back pressure may well open the bypass valve even though the filter looks clean.
The soot that turns the oil black is almost the perfect thing to fill those voids, just saying.

12 bucks for a new oil filter and you don't bother to change after changing the oil. So let the oil and filter both go for 20,000 miles, 30,000 km's.

I agree that $12 for an oil filter is not a big expenditure, so why skip. I went from being a cheap bastartd - however never skipping an oil/filter change - to buying the best oil money can buy. I did run Rotella from 2003 to 2020 which is a great quality oil for the price.

Oil filters for TDIs cost a lot less than $12. A good quality MKIV filter is $5.

I buy them bulk so I forget how much they are; I was reading a few replies up about $12 that's was the reason for my reply.
