Many years ago I bought a new SAAB with a Ford V4 engine. I had once been told that when starting with a cold engine you should drive as if you were 'running in' until the engine reached the normal working temperature. Do you think that this advice is still true today? I always did this, and ran the car for many years. On one of the service visits the man who ran the garage, from where I bought the car, told me that the engine was in the best condition that he had ever seen in an engine with so much mileage. I have a neighbour who has a Honda, which is not kept in a garage. He always drives as if he is in a hurry, tearing up the road every morning, even when it has been minus 15c overnight. What do you think about this?
