    We like to serve our customers in other ways too. One service we provide is that we tell you when your dad is full of beans. If your dad has been yelling at you for years to let your car warm up before you drive it, we are here to tell you that your dad was maybe just plain wrong. 

    To be fair, this practice wasn’t always wrong. In the past, it was prudent for drivers to warm up their cars to prolong the lives of their engines. To understand what we are talking about, we first need a little lesson about the internal combustion engine

    Here is our little lesson about the internal combustion engine.

    In an internal combustion engine, air and vaporized fuel are compressed in a piston. A spark plug causes a tiny explosion, which causes the engine to work. 

    Carmakers know that when an engine is warm, the gas will evaporate quickly. They account for this fact by injecting the perfect amount of gas to use under warm conditions. And since your car engine is warm when it is running, the amount of gas is accurate most of the time.

    For older cars, the amount of gas that would be injected was the same, regardless of the temperature. But if it was cold outside, the gas would not evaporate as quickly. This meant that the extra gas had to go somewhere. Unfortunately, the excess gas would leak out of the cylinder and wash off the lubricating oil that covered the other vital parts of the engine.

    Since your car needs this lubrication, the leaking gas would cause stress on your engine. This would shorten the life of the engine and thus reduce the life of your car.

    How smarter engineers fixed this fuel problem.

    Smarter engineers figured out a way to adjust the amount of gas that would be compressed within the piston, depending upon the engine’s temperature. This means that in newer engines if it is cold outside, not as much gas is injected. This means that there is no extra gas leaking out and causing problems.

    We know this is a simplistic way to describe a car engine. There’s a lot more going on under your hood than we can explain in a 750-word article. Your take-home message should be that warming up your car may not be necessary.

    Your dad was partially right.

    Even though super-smart engineers partially fixed this problem of altering how much gas is injected based on the temperature, that does not mean you should jump into your freezing car and immediately enter the on-ramp of a 70-mile-per-hour highway. Instead, run the vehicle easily the first ten minutes of your drive. 

    If you are driving an older car, your dad could still be correct. Look up the manual for your car and actually read it. See if the manufacturer recommends warming the vehicle under certain conditions.

    Your dad isn’t always wrong.

    One thing that your dad is right about is that you need to clear off your windshield before you drive. Even if you do not need to warm up your car, you still need to make sure you are not operating your vehicle with obstructed vision. Driving with an iced-over windshield is unsafe for you and dangerous for those around you. Even if you can see the cars directly in front of you and behind you, you won’t be able to see the car sliding into an intersection as you are crossing it. You also won’t be able to see the kid darting out into the street because he thinks you are going to stop at the crosswalk. 

    Another thing your dad was right about is that if you find yourself along the side of the road with a car that doesn’t function, don’t try to figure the problem while standing beside a busy highway. Instead, call All-MD Recovery and Towing. We will tow your vehicle to a safe location.
