The honest answer
There is no single mileage that fits every car. The right interval depends on your specific vehicle, the type of oil it takes (conventional versus full synthetic), how you drive, and the weather you drive in. Older cars on conventional oil were often changed more frequently, while many newer vehicles running full synthetic go longer. The two sources that actually apply to your car are the maintenance schedule in your owner's manual and the oil-life monitor on your dash. If your vehicle has that monitor, let it do the math and change the oil when it tells you, or at the manual's time limit, whichever comes first.
Signs it is time, and why it matters
Beyond the manual and the monitor, get the oil checked if it looks very dark and gritty on the dipstick, if the level is low, if you see an oil or check-engine light, or if it has simply been a long time since the last change even on low miles. Oil breaks down over time as well as mileage. Clean oil protects the engine, keeps it cool, and is one of the cheapest ways to avoid an expensive repair, so it is worth staying on schedule rather than stretching it.
