Does idling your car use more gas than when the car is actually moving?

Does idling your car in sub-zero temperatures use more gas than it does in say 30F degree temps?




(I usually warm up my car for about 10 minutes before I leave for work. That defrosts the windows so I don't have to scrape plus makes the inside nice and toasty.)

For the first question, I would think idling uses less gas since going slower uses less gas.  Not sure about the second question.

According to my vehicle's computer, idling uses far more gas than actually driving.  It is also more polluting because it doesn't burn the gas fully.  It can be very hard on the engine and not recommended.  My vehicle also has synthetic oil and it is recommended to only let it idle for a few seconds, even when it is cold.

It probably uses less gas to idle when it is cold than when it is hot, since the heat produced is used, rather than the cooling system having to kick in to disperse the heat.

I would only warm it up long enough to get the windows clear, with scraping.

If you have a block heater, plug the car in for a couple of hours before you drive it, even if it isn't -40. Anything less than -10 C, I'd plug it in.  It'll help warm the engine and the oil up and help divert that heat to the heater and defroster more quickly.

I'm lucky; I have room in my insulated garage so no scraping for me, unless it snows/sleets during the day while I'm at work.

There is a purple and orange root vegetable, known in the UK as a "swede".

In the US, I believe it is called "rutabaga"?

How is this pronounced?  I want to say root-a-bag-a, but then wonder if it's "root-a-barg-a"?

There are numerous online sites that pronounce words aloud for you.  To find one, I just Google "pronounce [word]".  Here are a couple of links for pronouncing rutabega.

There's an easier way to make scraping less of a chore, at least if you live in the US.  RainX.  Its a hydrophobic coating you apply just like spray-on car wax.  Wash the windows, spray, rub to spread it evenly, let it dry, then spray lightly with water and buff.  Turns 20 minutes of scraping into 5 minutes of scraping.  Buy it near the spray-on car wax. 

For my side mirrors, I pull a sub sandwich bag over the mirror and hold it on with a rubber band.  Pull the bag, and the frost, off before I drive away.


I park in the garage at night, but snow and ice often starts during the day while I'm at work.   And occasionally I have to work well into the evening, not leaving work until frost is forming.

Rain X, sandwich bags on the mirrors, and a car cover when it's not in use. The car cover keeps water off so there's not really much ice on the windshield and whatever there is, with the RainX, not an issue.  No garage (I dream fondly of the day when I can have one!) so... that'll do.  I don't like to idle the car and won't if I can help it for reasons mentioned above.

Hmmmmm

Are you basing that on seeing a change in the estimated miles per gallon? Because if so, the reason you are seeing it lower is because your sitting still but still burning gallons. So the average goes down.

Idling uses a quarter to half a gallon of gas per hour. (Source is fuel economy.gov). If I have a car with fuel economy of 25 mpg at 50 mph, after driving one hour I would have used 2 gallons.

In most cars you burn more gas the faster you drive.

Good point - I didn't think about it that way.  But really, it is affecting your overall gas mileage significantly because you are burning gas without going anywhere.  And from everything I've read, it really isn't very good for your engine.  If I get stuck in traffic and it is obvious that it is going to be a while before I move, like when I get stuck at a train crossing, I'll actually turn the car off.

My car does that for me - the engine shuts off when I put it into neutral and stop fully. It's one of the many reasons why I love it so much!

I put a sheet over my car windows at night, and in the morning when I start my car and whisk that off I shake the ice out of the sheet and hang it in the house for the next night.

How often do you have to reapply the RainX?

And it isn't just great for frost.  My brother swears by it.  His wipers died while it was raining and the RainX allowed the water to bead up and sheet off that he didn't really need them.

You have to reapply it once a month or so, I think.  It was enough of a hassle that it wasn't for me - plus I get to park in the garage in the winter so I don't need it the same way.

Prestone Windshield De-Icer. Spray it on a cold windshield, wait a few minutes and the ice/frost is whisked away by your wipers. Magical stuff! And if it's really tough ice, there's a scraper built into the can so no need to grab another utensil.

I'm guessing that this comes from the computer trying to calculate gas mileage from a non-moving car and that will make it report poor efficiency because idling means fuel burned for no movement.  However, an engine at idle will burn a lot less fuel in a given time than an engine in a moving car.  It is more polluting specifically due to the reason you mentioned, but as to it being hard on the engine in most cases it's really not.  There are situations where it can cause problems if you idle for excessive periods for many years (like a taxicab or police cruiser) but for most people they just don't idle a car long enough to cause any sort of problem other than fuel waste and increased emissions.  The recommendation on synthetic oil isn't meant to be a warning so much as an assurance that it's not necessary to idle the engine as long to get it to optimum viscosity, unlike natural motor oil that can lose viscosity (and therefore the ability to protect engine parts) more readily in cold conditions.

"If I get stuck in traffic and it is obvious that it is going to be a while before I move, like when I get stuck at a train crossing, I'll actually turn the car off."

That's still a good idea just because of the fuel waste issue.  Gasoline ain't cheap.  :)
