How long does it take to run a car in?

So you believe that an engine going into a run of a mill production car is bolted into the car without ever being run or tested?

And you think I'm daft?

The engine is bolted in, when the car is fully assembled the engine is switched on, the car driven from 1-3 miles and it is turned off again.

Well they are usually run in on a bench in modern cars.

Nope, a generic car maker doesn't have the time nor money to do this.

Yes, daft in the fact that you do not have a clue about the subject in hand. There is a big difference in production terms between testing and running an engine in.
