I just bought a Ford Ecosport and it has been only hours old. The dealer told me to drive the car at as slow speed as possible for the first 3 months (not more than 80 kmph) although my car can easily top upto 160kmph. He claims that I need to do this to "settle down" the engine and thus obtaining better mileage at a later time.
Generally, this driving-slow-your-new-car a myth or it really gives mileage later when followed properly?
