A popular belief among car owners is that they need to let their car warm up for several minutes before setting out on their drive. The idea behind this is to let the car\u2019s engine get up to temperature by running idle for a few minutes, all to protect the engine\u2019s longevity and performance. The reality of things, however, is different. Idling your car for a few minutes wastes not only your time but also valuable fuel.<\/p>\n

It\u2019s advice from the carburettor age!<\/h2>\n

Whoever told you that you need to idle your car on a cold morning to \u201cheat things up\u201d could be stuck in a bit of a time warp. Before 1980, most cars had carburettors, and these engines did need to warm up in the winter. Why? Carburettors regulated the air-fuel mixture within the engine and could not accurately adjust the air-to-fuel ratio in cold weather.<\/p>\n

Electric Fuel Injection Systems<\/h2>\n

Nowadays, practically every car sold in America has an electric fuel injection system that helps maintain the perfect air-fuel mixture needed for a combustion event, no matter the ambient temperature. Ergo, warming up the car before driving on a cold day has become a thing of the past. The sensors in your car\u2019s electronic fuel injection system are regulating the air-fuel mixture in real time, regardless of the temperature outside.<\/p>\n<\/div>
