Mom just bought an 05 Civic VP. Under "normal conditions" the OCI is 10k.
What makes Honda different than all others?

Why does Honda recommend 10k OCI?

GM OLM can go to 12k miles, BMW can go 15k mitsubishi 7500 with alot of other cars in that range forgive me if I don't bring them all up. Not different, just modern engines with modern oils.
That being said If I go to the max recomended manufacturer OCI I like to use a decent synththetic.
There is someone in the UOA section about to post a tremendous OCI per the OLM with conventional oil.

Good question. It is interesting how many problemengines slip through. I think it is more to do with corporate deadlines on the release of "new improved engines" than on sound enginering. To meet these deadlines to keep up with the competition I am sure new designs are marketed before they are proven.
More unexcusable is having a known design issue and not addressing it.

Does it still say 10k or 6 mos. whichever comes first, with filter change every 2nd time?
I have a new Honda Ridgeline truck with the VTEC V6 engine. The manual does not talk at all about severe or normal service. All it says is that you should use 5w20 and go to a heavier weight oil only if you do a lot of towing.
As far as the OCI goes, it does not specify for this truck except to say change oil only when the OLM shows an oil life expectancy of between 15% and 0% (these percentages are the service due signal and service past due signal, respectively). Ridgeline owners have reported that the 15% initial service due notice comes up between 5,000 and 7,000 miles, depending on driving habits. You could probably go another couple Ks until you hit the 0% signal.
The manual does state, however, that if you drive so few miles that the service due notice does not come on at all, then change the oil once a year.
What Honda has now done it appears, at least with this engine, is use the OLM computer chip (which is probably very similar to the GM OLM) to measure oil depletion factors rather than use a mileage/month basis for its OCI. Their OLM takes into account driving habits such as short trips by factoring in engine revolutions, oil temps, etc.
Although the OLM can not be 100% perfect, it seems to me that it has to be a more accurate indicator as to proper OCI for the Honda engine than simply saying something like X number of miles or X number of months. That seems old hat and arbitrary to me although I must admit, until I bought this Honda, it was 5000 miles/6 months for me no matter what with every car I've owned. After my second oil change, I will get a UOA and see if this thing is really as accurate for OCI as I think it is.

I have been very pleased with the 10k OCI intervals, on oem conventional oil no less! If I decided to stay with conventional oils, I would probably use 1 of 5 top conventional oils such as ExxonMobil 5w20 Superflo.
At 10k, I went from the oem fill to Mobil One 0w20 and so far it has been running app 8k miles. The fuel mileage is better and the engine runs even smoother. The oem recommendation to change the oil filter (every other) out at 20k and will change the oil also. With the Mobil One 0w-5w20 I would have no qualms running 15k-20.

The '84 Accord shop manual (as published from Honda) is 7500 miles or 7.5 months, whichever first. Can't even recall the oil grade back then - SG...?
Is there a Honda out there that has ran 10k oci's for most of its life and has over 100,000k miles? I'm just curious.
Based on my current yearly mileage I should be able to tell you in 4.555 years and 6 total oil changes
.
I would love to know how those oil life indicators work. They presumably count hours of engine operation and probably track and integrate other operating parameters, as well.
European VW Passats have OLIs. Since Americans are evidently believed to be too dumb to use them, American export Passats have a "one size fits all" 5k mi / 8k km OCI, with fine print in the owner's manual suggesting unspecified more frequent service for severe conditions.

Less frequent oil changes make the cost of ownership for the first owner less. That car could be a little more worn at the end of use by the original owner, for most owners. Evidently it's working, but not in every case. There are some sludge motors out there, for whatever reason. If you are a long term owner the safe way to go is to be a little more consertive and change a bit more often. It appears that if you are a 3 year or so owner, the longer oci's are working just fine. There are a lot of good oci's for longer intervals but I'll bet you that some of those owners posting here, take a little more care in ownership and driving than the general public, just a guess.
An example. I have a neighbor that uses the oil light to tell him when to add oil. He changes his oil at a quick lube place when he remembers it and trades every two to three years. I don't think he is the type to lurk around bitog. Instead he puts his money into the car wash, wax and vacuum, once a week, and parks the car inside the garage. He says that his return on investment is much better because the car looks good. This guy is like a lot of people and it's proof that car are well designed and built.

I once owned a 1989 Honda Accord 2.0 EFI. It was maintained with 10w30 dino at 5k oil and filter changes. At 200,000 miles there was no oil consumption and it passed the emissions test. I sold the car to my neighbor who drives it 60 miles daily. It now has 230,000 miles and runs perfectly. I hope to get the same or better performance from the 2003 Accord 2.4L ivtec with Connoco/Phillips 5w20 blend and Wix filter at 5k oci's.
In regards to the Honda OLM, I wish they would do one thing that GM does and that is display an Hour Meter. You know the info is there, I wish they would just display the info. ( its not displayed on my 05 Odyssey )
On my father's Tahoe he has a total hour meter that cannot be reset.
The Tahoe has about 21,000 miles and 402 hours of use for a very nice average of ~ 52 miles per hour.
I feel its nice info to have available.

Ok, this is not quite off topic, but I do have a question HondaMan: Do all newer Hondas have the OLM, or just certain models? I have a 2004 CR-V and it doesn't have one.
That would certainly help verify those used car, "they are all highway miles" claims.
Yep, 12,650 mi. on Havoline 5w-30 dino.
10K under "normal" driving conditions (ex. 50 mi. 80MPH FWY commute daily, each way). Honda engines tend to be quite easy on oil, and don't run as hot as Toyos. Thus, the longer oil life.
Personally, I'd start out with a 4-5K drain and extend drains only when analysis shows its possible.

I agree with Wan. My car is the same. 10k under normal conditions, 5k severe. I still a synthetic is your best bet to keep deposits at a minimum. Toyota once recommended 7,500 miles and we all know what happend with that.
They obviously didn't test the 3.0L V6 as well as they should have.
I sometimes wonder how these sludge engines pass the validation testing at their respective manufacturers' labs.
