Get Rid of the Idling Myth Already

It is a common belief that cars need a few minutes of idling to get going, particularly in cold weather. As a result, it is now common practice in the Unites States and other countries in the Northern Hemisphere to start up a car’s engine a few minutes before actually starting the journey. The trend is naturally much higher among owners of cars that have a remote starter. But new studies reveal that Americans and other Northerners are, in fact, idling their cars too much, causing worse damage to the environment than if they had just started the engine and driven off.
It is true that a small amount of idling is necessary in cars on cold days, to get the engine working smoothly. Regularly driving a car without properly warming up the engine first can cause a drop of up to 12% in the car’s mileage.
However, if you own a modern car, chances are it is fitted with electronic fuel injection instead of the outdated carburetors. It is not widely understood that only cars with carburetors have to rely on idling to get the engine warmed up. Fuel injection gets around that problem by applying sensors to gauge the correct amount of fuel and air needed to make the engine work just right in any temperature. This removes the need for idling, since the sensors will just switch to the cold weather settings when you start up, and will gradually shift the engine to a more moderate configuration on their own.
Indeed, today’s auto experts recommend an idling time of no more than half a minute, even for cars with carburetors!
