Apparently You Shouldn’t Be Heating Up Your Car On Cold Winter Mornings. The Reason? I Had No Idea

Plan on starting your car a few minutes before getting into it on this bitterly cold day? Maybe shorten the amount of time, as idling your car is not actually the most efficient way to get it warm, or the best for its health.
The idea of letting your car idle before driving it so the engine can warm up to optimal temperatures dates back to the 80s and early 90s when vehicles were built with carburetors. Modern-day fuel injection technology, advanced computer systems for delivery that automatically adjusts distribution in whatever temperature you're in and common, thinner synthetic oils get your engine lubricated much quicker.
