Idling our cars to warm up the engines is standard practice during the cold days of winter, but how long is too long? Government guidelines recommend no more than two to three minutes of idling on cold winter days. Using a block heater, if you have one, helps with cold starts. Also, the wise use of remote car starters is important in avoiding excessively long warm ups.
Not only does idling waste fuel, it also contributes to air pollution. Health Canada estimates more than 5,000 Canadians die prematurely each year because of air pollution and children are the most vulnerable.
