Again, some yes, some no. It depends on the vehicle.
BMW varies the Oil Service and Inspection Indicator lamp system that uses Mileage, Engine Temperature, and Engine Speed to calculate 'Estimated Mileage' that triggers the lights depending on these factors.
Older fords and Cadillacs used something similar.
I can't remember the last time I saw one that was triggered just with mileage (but I'm sure it was a model before 87).
GM has a web page describing their system, based on engine run time (total and per start), coolant temp, rpms, and maybe ambient temp as well. I think I remember being told that to clear the light you turn the key on but don't crank the engine, then floor and release the gas pedal three times.

All Hondas are mileage only.
My wife's 97 Buick GenII 3800 just triggered the change oil light at 2600 miles since last change.
I intend to take over the changes now. Does this feature automatically reset, or do you have to manually reset it?
It has to be manually reset. Check the manual.

Interesting. I've been reading a book on Ford Electronic Engine Control EEC-IV ("eek four"). They call that WOT, wide open throttle. It's significant in some tests, etc.
I've been getting a check engine light and the MIL (malfunction indicator light) code is 332, insufficient EGR pressure. The crate drives normally, so it's not a problem. Yet.
This morning I pulled the EEC unit out and opened it up, kind of neat how they built it with a decent amount of thought towards making it reliable. The PCB is coated with this soft thick plastic, so I would have to do some work to get that off before I could do anything, if I had to. Fortunately the VREF voltage is right on 5.00VDC so I know that that's okay. Some of the sensors are supplied with it, and one I measured looked like it was zero. But now I think I was not measuring the right pins. In any case, I did some checks to one vacuum solenoid, and it's ok, but the other sensor has eluded me, I've looked for it and came up with nothing.
The book is a general book ($30 at barnes and noble) and doesn't get into specific models, so I may have to get the ford factory manual to find out what's going on. Meanwhile when I unplugged the EEC module, I reset the memory, so if the check engine light comes back on, if it comes back on, I'll just keep on looking for more info.
If she does a lot of very short trip driving, you might do well to heed the light and change the oil. The parameters it monitors to trigger the light sound valid. You have to manually reset it, the method varies with make and model.

Most new cars like honda's etc still use mileage as there indicator light. Some also give you an option to change this number so the indicator shows up after that number of miles driven. This is particularly good because of different types of oil and driving conditions we go through. I mostly use Synthetic oil and therefore have to set my oil change either by 5000 miles, looks or 6 months interval. It is a good idea to change it after 6 months anyways due to the oxidation factors of the oil which kills the detergent in the oil after it is first exposed to the air, it seems to hold up for only 6 months or so.
Some people go for over 3000 miles every oil change and I kinda disagree with that in some ways, unless you know your driving conditions. If you are a highway driver and use conventional oil then I'm sure you can go way over 5000 miles or so. I have opened up engines with 3000 miles regular oil changes with only normal city driving being nasty inside with all kinds of sludge.
I would say follow the manufactures recommendations mostly because those numbers are tested to work best on that particular car. As far as type of oil is concerned, viscosity matters so go with manufactures recommendations also. On mine I have seen better gas mileage with 5W-30 Mobil 1 synthetic.

I agree with you here. Stick with the manufacturers recommendation for oil viscosity and grade and their intervals.
