What is your claim based on?
Do you have any sources, research, or data to support this claim?

I put 185K miles on my Honda Accord over 13 years.
Always following the MM system, and usually not changing the oil until it got down to 5%.
Not a single issue with that vehicle.

yup, same here

300k miles on our '05 Odyssey, and 200k on our '11 CR-V. Both followed the MM system. No issues whatsoever. Will be doing the same with the Civic.

Prior to the MM system, Honda's published reccomended OCI was 10k miles on their 4-cylinders. And that's with conventional oil!

I've had 3 vehicles I purchased new, and me/my wife drove them each for 10+ years and 150K miles.
Never once did I deviate from the manufacturer suggested maintenance.
Not a single problem with any of my vehicles.

What would Honda / Toyota have to gain by intentionally reducing maintenance to the point that cars blew up after the warranty expired?

Their entire brands are build on dependability/reliability/longevity.
No one would buy these brands if following the manufacture-recommended maintenance schedule resulted in the vehicles self-destructing after 5 years.

i had a friend who had a 08 accord he would not change the oil because it leaked so much it changed it itself! he would just add random quartz here and there....

i do random oil changes..sometimes 1k sometimes 7k sometimes i go blend...sometimes i go full synthetic....keep the engine on its toes.

It is "going ballistic" for a reason.
It calls for an oil change after 1 year even if you have not driven the requisite number of miles.

that's what it calls for but it is stupid.
2k does not require an oil change.
oil oxidizes on a much, much longer time frame than one year.
i will change it in the summer, when it will have a whopping 3k miles.
i had a del sol i drove 500 miles a year. it got changed every three or four years. it is fine.
once you have a classic car type car, you realize the "once a year!" is just a money grab to get you in the hands of the dealer service.
engine heat is what oxidises the oil. oil is not a magic pumpkin that turns into a fairy at the 365 day mark.

My claim is base on "Better safe than sorry." and "An oil change is cheap insurance." These are the same reasons I changed the oil more often than necessary in my 100k mile Honda VFR the last few years I had it.

No, I don't have any empirical evidence. So to the OP, please feel free to ignore my posts on this topic.

Might my car be fine with 10k oil changes? Sure. But for less than $100 a pop, doing them a little more often is not going to bankrupt me and it's not bad for the car, but it is good for my own peace of mind.

When I had the free oil changes from Honda I would do mine in-between MM codes 😎

Not to beat the dead horse being beaten, but unless you care about the cost of oil or just how much time you'll spend doing your oil changes, there is technically no downside. The happy medium is why the MM exists.

If we lived in an ideal world you'd change fluids after every drive.

Oil is dirty LONG before the MM says it is, just look at it, yes it still has x% of whatever it's supposed to have lube wise but it LOOKS DIRTY, and even if nobody is gonna see it but me and it doesn't really matter I still want it clean , just like my underwear...
what if I'm in an accident? Dirty oil on the road ? Not from me buddy !

I used to own diesel VWs. One trip around the block would turn the oil "dirty". I always changed my oil right about 10k miles. Never an issue.

Mine looks brand new up to about 3k, then starts turning , yours is dirty around the block because of crud that has built up and doesn't drain out ...
People can never change it if they don't want... be hard to find many engine mechanics that go 10k in their personal cars... imho ...

Mechanics favoring changing their oil 3-5k still doesn’t take away that none of them have any proof that changing modern day oil at 10k does any significant damage to an engine over its life.

People go crazy 🤪 cleaning the outside and shine this and vacuum that but have no issues with all the filth that they can't see ? My engine bay gets wiped , pressure washer attachment to get underneath (wand with wheels on it ) and another I made to hook around and get the suspension really good, clean the glass for ever and all the other stuff , but I'll just let black oil circulate though the engine because it's not technically done yet? Because it's not from a dinosaur like old people had to use and it's bad for the planet to change it to soon ?

If your anal about a clean car , as am I, I don't see how you can run dirty oil 🤔, even if it only "looks" dirty and is technically ok , it would bother me , hell it bothers me now that some here not only do it, but promote it ? "Dirty oil? How far can ya go ?" Is that the thread ?

5k because oil changes are cheap and engines aren’t. I don’t care who’s uncle had a 1991 Honda whatever that ran on water instead of oil for how many miles, modern engines (even hybrid) are harder on oil and oil changes are cheaper than modern engines. I trust the guy below and my own experience over some random newbs here who have provided nothing but rambles of anecdotal “evidence”. Talk to any competent mechanic and they will tell you to never follow the MM because most people actually fit into the severe category. But don’t believe me, believe some of the most respected automotive YouTubers/engineers/mechanics below

7:00 mark here -

Hybrid specific (haven’t watched this one)

How often are you all getting oil changes on your hybrids? I’ve scheduled my first one and I’m at 6,000 miles. The display shows it’s at 50% life but I’m not waiting until it goes down to 0%. I would have had it done at 5,000 miles but I was on a road trip over the holidays.

I’ve looked in the manual and couldn’t find a recommended mileage to get this done.

Just bought a 2025 Civic Hybrid yesterday. I'm too am surprised there are no oil change intervals listed in the manual. Also surprised a full synthetic oil is not specifically recommended. That makes me believe the factory fill may not be synthetic. Because of this I'll probably do the first oil change around 3k to 5k. I'll use a full synthetic 0w20 and then plan on 6k to 8k intervals unless the maintenance minder recommends earlier.

Some people here: You must change the oil every 3-5k, turbo or not. Break in oil change every 100 miles until 1k. Engines are expensive, oil isn’t.

If you change it per MM, it’s definitely going to grenade right when the warranty expires.

"You must change the oil every 3-5k..." That's nonsense, but if it makes you feel better....
