The Stegosaurus disappeared more than 100 million years ago, doomed by its tiny brain and a changing world. Then we come to the carburetor, a crude fuel-mixing device that once ruled the automotive universe.
Today, the carburetor is largely extinct, kicked aside by the modern fuel-injection system. Yet millions of drivers still seem to be stuck in the Jurassic Period. I thought of this recently when I watched a man spend 10 minutes warming up a fuel-injected Toyota that could have been driven seconds after it was started.
Few processes are as poorly understood as the cold-weather start. Back in the days of carburetion, a car couldn’t be driven until it was warmed up. Today, warming-up is a counterproductive exercise that wastes fuel, harms the environment and damages your car. Let’s have a look at the science, history and flawed folklore behind the automotive warm-up:

Vehicles with Turbos should be warmed up until the oil is warm...that’s more than 30 seconds and this is specially important in single digit or colder temperatures.
A turbo spins 100,000-200,000 RPMs. Needless to say cold oil does not lubricate properly.
Also it’s nice to have the ice melted before taking off.
Warming up a vehicle a couple minutes in cold weather is not about the ignition system. It is about not stressing cold engine parts especially when oil has not coated the parts sufficiently.
Here in MIchigan we let them warm up so they will be warm inside. I think that's the whole purpose now.
You can start driving immediately, but it’s a good idea to be gentle with your car until it’s ready.
In other words, don’t go out and floor it immediately when it’s stone cold.
Manual chokes back then too. Using them and how to apply the accelerator during start was indeed an art.
I warm my car up so my ass doesn’t freeze to the seat. Then there’s the fact there is a sheet of ice on the windows that needs to be removed before I can safely drive.
Screw these people.

My 57 Bel Air and 67 Camaro take exception to this article. They like a bit of warmup.
Ya'll need a seat warmer like I have. Feels so goood ...
You got it : it’s important for the oil to circulate back up to the engine.
I have heated seats. But they do take a few minutes to come to temperature.
With my old trusty car, I have to let it idle for around 30 seconds to let my steering fluid warm up.
That's what I always believed. I start the engine, then let it run for a minute or two to get the oil out of the pan and into the engine and transmission. Then, I drive away. If it's cold, by the time I'm on the main road, the heat's working (but my coffee's already been helping with that).

I was not aware that the oil sump in internal combustion engines had been moved to the top of the engine.
I reject the premise that "warming up" was the result of "fuel mixture issues."
There is no way to drive away at idling speeds; anything above idling speed increases wear on the entire engine, before oil distribution throughout the engine takes place.
There is actually an “Anti-Idling Law” in New Hampshire.
The should post a copy in the Unemployment Office.
Lets see! Cold oil in cold pan, pumping to the top of cold engine with cold valves. Valve sucks going through piston sending connecting rod through side of block or down through pan. Save ten minutes or buy 3K to 5K engine. U.S. Military says warm up the tank-truck-Humvee-or?- before you jump on the pedal. Keep your car in a warm garage or use a block heater.
I warm up my car before driving it. Even have a timer set, the computer will figure about how long it will take (around 10 minutes on a cold day) to do so prior to planned departure time.
Then I unplug it. Nice to have it warm _and_ the battery fully charged before getting in. I like my Leaf.
While a long warm up is not needed except for driver comfort. However, I wait a few minutes after starting your car in very cold weather to allow cold oil to get to the top of the engine and not do a jack rabbit start until the engine warms. My overhead valve engine uses 5W-20 oil, but at below zero temperatures there is a little valve noise when starting until the oil gets to the valves. I have experienced -26 temps and believe me you need a couple of minutes to get that oil flowing
