Now that the weather has gotten colder, the Éco-quartier NDG staff see more and more drivers iding their cars (leaving their cars running while they run into a store for example).

According to experts, it is not necessary to idle cars in winter for more than a minute because it is not worth your time or gas. It seems to be better to start the vehicle up, let it run for just 30 seconds to one minute and then start to drive, because otherwise it’s a waste of fuel and bad for the car engine. Under normal conditions, the car engine runs on a mixture of air and vaporized fuel (for example gasoline). This mixture enters a cylinder and a piston compresses it. This generates a combustion which powers the engine. When it’s cold outside, the process works differently because gasoline is less likely to evaporate. The car compensates for this by adding more gasoline to the air-vapor mixture which is wasteful.  Furthermore, the police warn that cars can get stolen easily if they are idling unattended.
