I live in Michigan where it’s currently 12 degrees, which means that remote car starter is as valuable to me as the Hope diamond (although thankfully, much more affordable).
Getting into a freezing car is the worst, andit always feel like as soon as it starts to warm up in there, its time to get out.
(Andthere’s no greater moment of panic and then relief when you realize that you accidentally hit the seat warmer and didn’t, in fact, wet your pants.)
With that said, it turns out that not only do you not have to warm up your car, but you probably shouldn’t do it at all.
It turns out that doing so can actually cause some serious problems, ones that aren’t related to your cold, bony fingers white-knuckling a frozen steering wheel.
This myth that most engines need time to warm up dates back to when cars had carburetors. If you didnt warm up the car, they could stall out bummer, especially in the winter.
But now we have fancy computerized fuel-injection systems that adjust themselves to outside temperature.
Sorry to break it to you, but warming up your car does not prolong the life of your engine. It is actually doing the opposite by stripping oil away from the engines cylinders and pistons.
(I wish I could say that’s why I do it, but nope, it’s because I’m cold.)
Let’s Start at the Beginning
We’re about to get technical here, so buckle up for a minute.
Internal combustion engines work by using pistons to compress air and vaporized fuel within a cylinder. The compressed mixture is then ignited and creates a combustion event, a small and controlled explosion that powers the engine of the car.
According toPopularmechanics.com, When the engine is cold, gasoline is less likely to evaporate and create the correct ratio of air and vaporized fuel for combustion. Engines with electronic fuel injection have sensors that compensate for the cold by pumping more gasoline into the mixture. The engine continues to run rich in this way until it heats up to about 40 degrees.
