The reason for preheating the car is to reduce friction by applying enough engine oil to the engine walls.
A minute or two is usually enough.
It is also necessary for engine oil, but also for preheating mission oil.
In the case of engine oil, the viscosity is low, so you can preheat it for about a minute
Mission oil has a high viscosity, so you have to preheat it for a longer time.
The mission oil does not necessarily have to be idle, so you can run slowly for about 5 minutes on low gear.
Diesel cars generally need to be preheated a little longer.
Still, cars these days have improved so much that a minute is enough for gasoline or diesel vehicles.
Turbo cars are also increasing a lot recently, focusing on high-performance vehicles.
Turbo cars need to be more warming up.
You need to warm it up well.
There is a well-organized article about preheating cars.

According to the above, it is enough to preheat for one minute even in winter.
