There are a lot of variables that go into when a car needs an oil change.
Generally, unless it is NOT a "free" oil change, the only thing the dealer looks at is if they "have to do it" (picture a 10 year old being told to do homework), or if it can be put off. If it is under 10k, they will put it off if you let them. Amazing how if you offer to pay they will jump at the job though.
Does that mean it should be put off?
Don't really know.
In my opinion, for lots of reasons no one actually wants to read so I'm going to not spend time writing, an oil change should never be put off. The suggestion isn't 10k miles, it is 1 year, or 10k miles.
The year starts when the oil is put in the engine, not when you buy the car.
Experts and labs says lots of things about minimums and life left and stuff with things on top for smartness. Then when something breaks they talk about statistics for expected failures and it being within the norms.
The mechanics who have scarred forearms from fixing stuff all agree, avoiding the break, regardless of "norms" is best..never put off an oil change if you want a long life out of your engine. Never, and 10k or a year is a little long. I did my own at 5, then the dealer at 10. About to turn 15k, going to change it again. Oil cannot be too clean, the cleaner it is the better your engine will run, period, no exceptions to this rule. Dirty is the same, dirty oil is bad, period.
How dirty? Don't care, doesn't matter.
How old? 1 year. just because it was sitting doesn't mean the factors that cause viscosity breakdown weren't happening. In many cases they are worse, engines and the oil inside them are highly engineered for long life under use, not long life while sitting.
Think about it this way.
Super smart people have Orange County, Ca convinced "toilet to tap" is a good idea (yes, they filter defecation out of sewage and put it back in service as tap water), because they ran taste tests and people liked the taste of the filtered poop water more than straight tap. Plus those super smart people are super positive the filtration tech is perfect and there can't be a health crisis from this. Thing is, they figured out even if it gets all bacteria (I doubt it, we'll discover a new strain it doesn't get eventually) it doesn't get drugs. So all the prescription and other medicines people take that get moved out of their system...that stays in the water. All the drugs flushed during police raids...stays in the water.... You may disagree, but personally I run everything smart people tell me through a "common sense" filter.
Common sense says don't drink water that has been pooped in, and change your engine oil often, both for a long trouble-free life.
