As I understand it, it is best to drive off quite soon after starting the engine, because the oil may not circulate well at idle, and not to use full performance for up to 15 minutes.
When I was unable to drive, every two weeks I ran the engine up to temperature. Typically about half an hour. Since then, on-road, about 2 or 3 miles.
That will just be the coolant. If you have an oil temp gauge, it's usually at least double whatever the coolant takes, possibly longer in winter. And one car has a gearbox oil temp gauge, and that takes about twice as long as the engine oil to reach normal temp.
