Huh. And here I was not giving two shiats about the engine being warm but instead wanting to wait until the heater's had a chance to make the car comfortable. So I guess I was being wrong, wrong.

I always did it to warm up the interior (not the engine) because in the days before Rain-X chipping the ice off was a royal PITA. Once the interior is warm enough the ice will just slough off with the help of a squeegee (and any snow will easily push off of the roof). Plus you won't be freezing your ass off when you start driving. The only chipping you had to do was the side mirrors.

As to the "Sensors" that's what a choke is for. If you didn't know how to use a choke of course it's going to stall.

That read like it was written where they have 'frost', but not 'frostbite after two minutes, and that's not accounting for the wind'.

At 20 below you're praying the thing starts at all. Good luck without a block heater, and best of luck if you saved a few bucks on a cheaper battery, cause you'll need all the cold crankin amps you can get. There is a little extra extreme cold maintenance that needs to be adhered to for reliability.

But hey, I've never found a scorpion or rattlesnake in my boot; for me, that's strangely worth it.

What I do on those mornings where my windows are frosted over: I'll get out the ice scraper and tend to the side windows, since the defroster does fark all for them.  After that, I get in my car, fire up the engine, turn on the front and rear defrosters and lightly place my foot on the accelerator to bring the RPMs up to about 1,000 instead of the idle level of between 500-750 RPM for the 5-10 minutes it takes to clear the windows.

In that type of temperature, warm the car.  I was listening to NPR on my way home from the office on Friday night and the "drive off, it's okay" applies only with temperatures above 20 F.

No, you should use an ice scraper and scrap it off, edge to edge, top to bottom and all of the side windows and the rear so you can farking see out of them clearly. Oh and if it snowed, brush the snow off the hood and the roof so you don't become a danger to yourself or others.

Carbureted engines: Start them up (bonus:If you're old enough to remember manual chokes, you get to sit there in the cold, adjusting the choke as the engine warms.) Go inside and have a cup of coffee.

Injected engines: Start engine, let idle for 15 seconds to let the oil pump warm the thickened, cold oil through friction. Drive easy until engine warms enough to show on the temp gauge. Turn on heat.

If I don't warm up my car before driving it, it won't go out of first gear.  It also causes issues with the oxygen sensor so my check engine light comes on and the car runs a little rough.

My husband who has been a mechanic for almost 40 years always drills into me to let it warm up first and knows when I don't.  He gave me the detailed explanation on why it's necessary a few times, but I can't remember accurately enough to detail it here.

I live in one of those climates where we very seldom see temperatures below 25 F overnight (the next three days being that exception, it's 17 F at 8:13 this morning), never had a snake or scorpion in my shoes.  Sure, had the cats go bat guano insane when they mistake the opossums for giant mice, the armadillos for armored mice and they keep wanting me to bring the big kitty indoors.  Screw them, I am not letting the bobcat in the house.

2018-01-01 09:18:29 AM  
I was going through a couple car-specific forums to try to figure out why it had a high idle at low temps. Apparently my car is programmed to idle around 2,000 RPM when it starts at cold temps (around freezing-ish) in order to get the oil and catalytic converter up to temp. Until components warm up enough, it's programmed to run at some default settings that royally suck in terms of gas mileage. Most of the year I get 31-34 mpg, but once late autumn hits I'm around 28 mpg if I don't let the engine get nice and warm before driving.

I'll keep warming up my car if it means I'm warmer on the drive and it nets me another 20-30 miles per tank.

Also, to my neighbor, warming up the car and revving it repeatedly for 20 minutes will not fix the loose fan belt and broken fan that are your actual problem.  I don't care how early you start; well, later would be better.

Carburetors mix gasoline and air to make vaporized fuel to run an engine, but they don't have sensors that tweak the amount of gasoline when it's cold out. As a result, you have to let older cars warm up before driving or they will stall out.

Or you apply a bit of choke and it all works just fine. Almost as if people thought about this and found ways of getting carburetted cars to start from cold.

gaslight: Apparently this expert has never heard about electronic ignition. Cars with computers in them -- like they have had since the 1980s -- automatically adjust the fuel - air mix for the temperature.


According to TFA it's the computer's fault for doing exactly that; Adjusting the fuel-air mixture to be more rich as to compensate for the poorer mixing in lower temperatures.


Sean VasDeferens: EvilEgg: Well, if electrics ever take over like they've been promising, this won't be a concern.

Because it's a standard feature to be able to run the heater/AC from the plug if it's still plugged in, letting you condition the interior without draining the battery.

For times when you have enough time to get a bucket of water hot enough to melt the ice off all the windows on your car, but not quite enough time start the car and scrape it like normal.

It's a razor-thin margin of efficiency.

My van has a diesel engine and the manual says to never idle it to warm it up. In fact, it has an auxiliary heater to speed the process.

a) Wait until the sunlight heats the car enough to defrost all the windows.
b) Start engine....wait 45 seconds. (Start Dashcam, GPS, Electric Ass Warmer*)
c) Creep onto the highway, drive 20 in a 45 for 1.7 miles to the 1st. traffic light.
d) Now drive normally.
e) Profit!!
