Piston Slap: Improper Engine Warm Up Procedure?

Sajeev,

Thanks very much for posting my question. Your answer and the comments from others were most informative. How about another?

We now have only 2 licensed drivers in our home. We do however have 3 licensed cars in the driveway. Please do not ask about the project car in the garage. 2 of the cars are our ‘daily’ drives, the 3rd is used primarily on weekends. We live less than 3 minutes from a 400 series highway in Ontario. That means that the cars can be required to reach highway speed before they are ‘warmed up’.

My normal practice last winter was to get up, start all the cars, turn off all possible drains on the batteries. Then take the dog to the park across the street, stretch our legs and let him do his business. After about 10 minutes we return. I then turn on the heater/defrost on the 2 cars that we will be driving and scrape/brush them. When this is completed, I turn all 3 cars off and go back into the house to get myself ready for work. You may all remember what last winter was like and the upcoming winter is supposed to be similar.

Now I understand that idling is environmentally irresponsible. And possibly against by-laws in some areas. That however is a discussion for another forum.
