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:

We didn’t have multi-viscosity oil back in the olden days either.
I would think that your car would warm up a bit faster when it is sitting still, so a short warm up period is probably not too bad a thing.
“Few processes are as poorly understood as the cold-weather start.”
True for the products of Pooblik Skrewl Collective Hives, but those things are also generally igorant about anything more technical than questions regarding condom texture.
In the American black kraals, those now known as Urban Ferals were, before the “Great Society” trashed them, able to keep a carb equipped vehicle rolling.
Yes, those vehicles were more ‘heap’ than ‘neat’, but they worked, as did their drivers.
LBJ & the “Great Society” fixed that, may G*d rot ‘em.
I have to have it warm WHEN I GET IN. Solly Cholly.
The myth about warming up your car on a cold day]]
It’s a myth that if you start your car, turn on the heater, and leave it for 5 minutes that it will be warm when you get in it- (It actually gets hot)
Here in Colorado where the temp hovered near 5 degrees, warming up the car is necessary to deice the windows and sometimes, the interior vinyl seats.
Little did realize that he was using me as his own "remote starter". ;-)
This is just another Global Warming Bull Crap story
Well, maybe it’s because it’s a Pontiac.
Bingo!
and by the way- warming up a car has more to do with wear and tear on things like pistons, rods etc- the oil is cold, and will not flow well, and if you simply start up then take off and floor it. you are putting tremendous stress o n things like the piston because they aren’t properly lubricated due to the low flow due to being cold
I warm up the gas guzzling Suburban every morning.
I warm up the old diesel because I feel like it. I like the way that sweet smelling black smoke wafts through the air to greet my neighbors.
and 2) because back then one needed skill to start a car on a really cold day.

Yes you did. I still remember the routine.
1. Turn ignition on.
2. Slowly depress the accelerator pedal twice to the floor. One second. And two seconds.
3. Foot off the gas - crank it.
If the car was properly tuned with points, plugs condenser, etc. - it would fire right up.
If not, then repeat the process. After it starts, leave it running for 3-5 minutes (or more), then kick the gas pedal to disengage the automatic choke and you’re good to go.
I warm the car up so that the windows will not fog up 200 feet down the street.
I’ve read this argument a lot recently.
Due to expansion and contraction i don’t see the upside of driving and revving with an ice cold tight engine with oil thick as sludge inside.
They claim engine tolerances are tighter than ever now which helps my point even more.
Not buying into this ... on a cold start in the winter the engine oil needs to warm to some extent to allow for proper lubrication. Not doing so puts additional stress on the engine. A warm weather start ... not so important
when it’s -10 out, the car might be “ready” to go but the driver and heater are not.
I’ll let it warm up.
If the windshield doesn’t need defrosting I drive away. If it does, I don’t. The car needs to “warm up” to defrost the windshield.
I admit it I’m stuck on warm up. I use those precious moments on a cold day to do a quick nail file session while waiting for the engine to warm up sufficiently to drive away from the house. :-)
I’ll warm up my car whenever I damned well please.
