Government programs decreased emissions and reduced attention to warming up cars before driving.
"Previously, drivers had to start their engines to warm up lubricants and allow them to properly flow to moving parts," notes James Shelton, technical manager for Jiffy Lube International. This was due to the fact that engine oil and other lubricants used to be much thicker.
“Engines and transmissions from the past were built with more space between their moving parts, which means they needed thicker oil.”
He says imagine a batch of old molasses being poured in January.
According to David Bennett, AAA's senior mechanic, an older-style carburetor engine might "stall out" if you didn't wait for the lubricant to warm up and loosen.
Modern Engine Technology
Things have changed. Present-day engines are made to warm up fast and not waste fuel by running idle for a long time.
"This practice is no longer needed since the development of fuel-injected engines," says Bennett.
Quoting directly from a source, the practice of letting an engine warm up before driving is no longer necessary. According to the information provided by Shelton, today's engines are built with more precise tolerances and utilize lubricants that flow (in most cases) like water.

Should You Let Your Car Warm Up Before Driving It In Cold Weather?
The question of whether to warm up your car before driving it "has two answers, depending on what the driver is trying to accomplish," says Shelton.
If the goal is to reduce wear on vehicle parts by starting the engine, letting it run, and allowing lubricants to circulate, this method isn't necessary anymore. But if the goal is to enhance passenger comfort, that's a distinct issue altogether.
On days when the temperature is a bit chilly, warming up the engine for a few minutes beforehand can make a significant difference in passenger comfort," says Shelton. "Many newer cars can be started remotely from a dry, warm spot using a key fob, eliminating the need for passengers to get into a cold vehicle. In addition, some cars are now equipped with features like heated steering wheels and seats, which greatly reduce the need to wait for an engine to warm up.
The process of beginning your car in the winter may become simpler with these ideas. Your driving is certain to be smoother and more enjoyable.
Through every window, for safe driving of your car.
According to Shelton, contrary to common belief, pressing the accelerator pedal or holding it partially or fully down will not enhance or speed up the engine's start-up or warm-up process.
Bennett says it's okay to start the engine, turn on the defroster, and clear the front and rear windows, as well as the side mirrors if equipped, for better visibility.
He says using the defrosters will help clear ice from the windows more quickly.
