Is it bad to warm up your car?The answer to this question depends on several factors, including the outside temperature, the age of your car, and the type of engine you have. In general, it is not necessary to warm up your car for more than a minute or two before driving. Idling your car for long periods of time can actually waste gas and increase emissions.
Importance, benefits, and historical contextIn the past, it was common to warm up cars for several minutes before driving. This was because older cars had carburetors, which needed time to warm up in order to function properly. However, most modern cars have fuel injection systems, which do not require a warm-up period.
