Its not wasting fuel but it increases the time it takes for your engine to reach operating temperature. it keeps your engine colder for longer, which is when most wear occurs.
most engines only need 10-15 seconds to circulate oil, then they're safe to drive. beyond that and you're just wearing out your engine.

Dude. If it gets that cold you should be checking on your coolant more frequently to make sure it doesn't freeze. This is not about driving it off cold. This is about you having an improprt ratio of coolant to water and living on an iceberg. Also its probably fake.

Also try driving a cold carburetor car. I didnt think so. There is a reason the warm up idle thing exists.

My grandmother was just visiting for Christmas (NYS) and I went outside to warm up my truck before I picked up my father. She told me that in Maryland and D.C. it was illegal to leave your car idling unattended and the cops would walk up your driveway and write you a ticket for it. She said it was because of people stealing cars in the winter when people did this but they slapped some environmental regulation reasoning into the law when they implemented it.

It sucks but I'm not going to drive in a 17 year old cold taco because Jamal decided he needed $200 bucks. Besides, I have the best anti theft there is, 5 speed.

A big 6L V8 at idle uses 0.09L of fuel in the 3 minutes you should be using.

Use the correct synthetic and this isn't a problem.
The REAL thing people should be worried about is manual transmission gear oil temp and diff oil temp, neither of which really heat up when idling.

>>16400954

He's saying that it takes much longer for the engine to reach operating temperature by just idling than it does by light driving, and because most wear occurs when the engine is outside of operating temperature, it makes no sense to prolong the time it takes to warm the engine.

Fuel injection engines don't need time to warm up, even in sub-zero temperatures. Give it a minute tops for oil to get around the engine and you're good to go.

I have a 2004 Mazda6 diesel, with Webasto parking heater, but without timer or remote controller. So if I start the engine below about 5°C=41F then it starts with a turbine sound and it warms up the engine pretty quick, faster than a petrol engine. So I just walk out, start the engine, and go back to the kitchen for a coffee. In less than 10 minutes all the ice even from side windows melted and it's warm inside the car. Of course the yard is closed, I don't park on the driveway with running engine. If I don't have time for that, the engine is warm when I reach the town border sign. Well actually if you want operational temperature for the entire engine, fluids, block, etc, than it needs at least 15 minutes driving.
If it's not that cold I only idle for about 1 minute while rev drops from 1000 high rev to normal 780.
>>
I left my car idling for an hour and a half sucking back a grand total of 2 liters of fuel while shoveling snow a few weeks ago and it fixed a ticking from the engine and the drivers side heat came back.

>>16403427
Your engine will heat up much faster under a light load than under zero load. A bit more wear for much less time is better than a bit less wear over a much longer time.
>>
>>16401142
It warms up at idle but there's zero value to letting it idle with modern fuel injection. Just drive the fucking thing and don't exceed 50% throttle while the car is warming up. If you don't drive the car you will be leaving the differential and transmission fluid cold which means that if you go full throttle the car will be subject to higher wear regardless.

>>16402446
It is commonly known that for modern EFI engines that in normal conditions above freezing that you can start driving basically immediately after the engine turns over but you should never drive aggressively until the engine is up to temperature.

For extremely low temperatures yeah sure go ahead and wait 1 minute to let the oil circulate first but sitting around for 5-10 minutes doing nothing is a waste of time and does nothing.

Get in, turn the car on, and go. Drive gently until your water and oil is up to operating temperature. If it's not a carbureted engine, you don't need to let it warm up. Simple as that.

I once had a fuel injected 2004 Cavalier that would shut off when it was cold until it was warmed up. It would idle fine, high but it would run. If you were going through town and took it out of gear to go around a corner or something and didn't put it in gear before it got below idle, it would shut right off. Had to stay on the gas at stoplights/signs to keep it running if you absolutely had to stop. Luckily it roll started like a champ, so as long as you still had some momentum you could start it up again without too much hassle.

Turned out the timing was a couple degrees off, which is why it would do that. But, it provides a useful example of why

>If it's not a carbureted engine, you don't need to let it warm up.

Mine goes from 35-36 average MPG to 33-34 average MPG when I let it idle for 10-15 minutes every morning, as compared to just starting it up and driving in the summer.

I drive close to 300 miles/week, so it ends up being a difference of ~$3/week, when comparing best MPG to worst MPG.

Properties are great, but what does it really do for most applications that can't be done almost as well by something much cheaper?

There's a reason we still use sand casting for engine blocks. The technology has been around in one form or another for thousands of years. But it still works well enough that any other method does not give enough benefit to justify a change.

That too. It's a multi-purpose example, isn't it great? Still though, the car was fuel injected, but had to be warmed up to run properly. Because of that, the statement

>If it's not a carbureted engine, you don't need to let it warm up.

is quite apparently wrong in this case, and very possibly several other cases as well.

Could very possibly be that the timing is off on yours as well. Mine would drop really low once you took it out of gear, like idle would drop to 300-400 RPM before coming back up to normal. Only figured out what my issue was when the timing chain guides shit the bed and the shop doing the replacement found the timing off by a bit.

And for the record I drive a 1 liter but I'd do the same with a V8 if I owned such a thing.

>>16406774
That's EXACTLY what happens when I come to a stop about half the time. It'll dip to about 500RPM, and typically it will go back to idle, but sometimes I'll have to tap the throttle to keep it from getting too low and stalling out on me.

Because the majority of engine wear occurs when your engine is cold. By starting, giving the engine 30 seconds to circulate oil and then driving like a grandma until you're up to temp, the engine warms up faster and wears less than if you leave it running for 5-10 minutes.
>>
>>16406846
oh yeah niggar
sand was used to cast what material? in what period?
Im being nice with you because you said the technology of casting engine blocks with sand is dated from thousand of years ago
>>
>>16400497
It's called "puffing" laws. I think the main reason would be people were turning on cars, leaving them unlocked, and running back in the house. Was too easy to steal.

Oh Jesus

Yes, you got me. We've only been casting engine blocks for a short while. However, the technology used, sand casting, has existed for thousands of years. Bronze age cultures utilized sand casting widely.

Engine blocks are more complex and we've refined the process, but it is essentially the same methods used by our ancient ancestors.

>>16406880

>and wears less than if you leave it running for 5-10 minutes.

I never understood how that worked.

Like, putting a cold engine under load dumps shitloads of fuel into bores with cold rings, dumping 10x as much fuel into the oil as if you just let it idle. Consumption skyrockets because the O2 sensors haven't come to life, so the engine is dumping enough fuel in to get a 11:1 AFR just to make sure the thing still runs and moves. Oil pressure goes through the roof, as the oil is cold and doesn't like to move, and raising the RPM just spins the mechanical oil pump faster, which leads to sky-high oil pressures and cavitation in the pump.

And somehow all this is better than just letting the thing idle for 10 minutes, with the absolute minimum of fuel being injected until the rings expand, while keeping oil pressures at safe and sane levels?

Like, really?
>>
>>16406421
Isn't this the equivalent of the old "no cruising" laws here in burgerland?
>>
>>16406421
Its only in urban areas and only if you constantly drive up and down one street to annoy the people there (loud music, loud car, etc).
>>
>>16406880
>>16406844
And my 1 liter heats up pretty damn quick if I get on it. Or somewhat slower if I too drive like a granny.

What I'm suggesting is that there isn't so much of a 'time to wear ratio' in which the quicker your engine gets up to temp the better but an 'engine work to wear ratio' in which the amount of work that your engine does before it gets up to temp causes more wear.

>>16406970
Exactly this.

>>16406893
fucking kill yourself you cherrypicking shithead, either you know damn well what he meant and you're just being a fuck, or you're so fucking stupid you DIDN'T know sand casting has been around as long as it has, because you were (are?) a failure in school.
>>
>>16406970
That's why you short shift and don't go WOT until it gets up to temp
>>
>>16407013
>>16406970
Oil pressure won't be sky high and modern heated O2 sensors reach operating temperature within 30 seconds of engine start. Do you guys even think about the bullshit you say before you say it? You aren't going WOT or high RPM while the car is cold.

Idle isn't even enough to get unheated O2 up to operating temperatures. If you read basic shop manuals they will say this: https://www.linkedin.com/pulse/how-test-oxygen-sensor-mandy-concepcion

Wait 1 minute max for oil to circulate or however long it takes to scrape ice off of windows. Idling beyond that is a meme.

>That's why you short shift and don't go WOT until it gets up to temp

Still under load, still pissing buckets of gas into cold cylinders, still diluting the oil with gas far, far more than you would be just letting it idle.

>>16407165

>Oil pressure won't be sky high

How do you figure? I've seen 60+ lbs at idle in a V6 work van, and I've seen it peg the needle under cold engine load. That's in 20-something degree weather, never mind below zero. Does this not qualify as "sky high"?

>modern heated O2 sensors

Not universally equipped on all cars.

>Idle isn't even enough to get unheated O2 up to operating temperatures.

It is if the car is relatively modern, and has the catalytic converter crammed up to the exhaust manifold. Hence why quite a lot of cars forego the heated O2 sensor.

>Wait 1 minute max for oil to circulate or however long it takes to scrape ice off of windows.

The oil will still be at outside temp, and roughly as free flowing as molasses at room temperature, even using the latest and greatest 0w20 full synthetic oils. At best, you'll kick open the overpressure valve in the filter, if you bought a decent filter, and start pumping unfiltered oil through your engine, assuming the pump isn't cavitating from trying to pump what is essentially mud at that point. At worst, you'll start popping seals.

Try visiting somewhere that actually gets cold, like double digits below zero. Fire your car right up and head on out just as quick as you like, and tell me again that it's perfectly fine for it.

Guess what muppet, I actually live in a place where at this time of year we easily get -15 and some days even dipping into the -20's.

I own a Golf Tdi, excluding having to wait a bit more for the glow plugs to works it's magic, the car fires up and at most after a minute, rpms settle to the usual idle and I'm ready to go on about my life.

The car is 8 years old. Excluding the battery changes for the cold weather I haven't had a single problem with it cold related.

So piss off with your neanderthal mentality.

That's cute darling, that's about what we have for a high temp here without the wind chill.

I own a Chevy Cavalier, excluding having to wait a bit more for for it to warm up, it's magic, the car fires up and at most after 15 minutes, I'm ready to go on about my life.

The car is 12 years old. I haven't had a single problem with it cold related, and I've let it warm up for 15 minutes every day it was below freezing.

So piss off with your neanderthal mentality.


See? I can be anecdotal too!

If you happen top think that having to wait 15 minutes before being able to drive anywhere is funny, yeah you can be anecdotal. Hell, you can even be the joke, like you'r being.

The gas in the oil is going to burn off as soon as you get up to temperature. Get the car up to operating temperatures and this is irrelevant.

Even when the oil is at outside temp if you have the correct oil for your ambient temperature as specified by the OEM the engine is designed to handle the higher oil pressure without excess wear.

Have you ever seen some of these prototypes? OEMs beat the shit out of their prototypes as far as driving goes because they know your average suburban mother is going to get in the car and floor it as soon as the car starts because the car is an appliance to be used and abused. They do this for all conditions and accelerate wear to simulate long term effects.

Just waiting long enough for the engine to circulate oil and driving with low load and low RPM is more than enough to ensure that the oil will continue to protect the engine sufficiently before it gets up to temperature. Oil pumps and filters are going to be designed to handle the load of low temperature use.

Unless you run OEM interval*2 oil changes with conventional because you didn't fall for "the oil change jew"

Yes, it actually does. I can let my car idle for 15 minutes and it will be at about 105oF, or I can drive it for 90 seconds it it will be at 130oF

There's your problem. Stop being a cheap fuck and change your oil and use full synthetic.
>>
>>16400480
Fucking retarded, most engine wear comes from driving and reving the engine above idle when the engine is cold.

Enjoy treating your car like shit to save a few drops of gasoline.

revving the engine above idle when it is cold is a good thing as it helps heat it up quicker
there's a proper way to do it ofc

>>16407666
engine takes 20 minutes to warm up when idling
Only takes around 2 to warm up under 3k rpm.
Which is better? Engine rotating for 20 minutes without good oil flow or around a minute or so with cold oil.

This would be a very autistic discussion if it didn't mean that idiots who idle wasted 20 miutes from their life when they could just sit in and go places.
>>
>>16407701
>>16407716
So why the fuck not start the car up immediately and drive around.

Higher rpm from applying gas from an idle or driving wears the engine down.
>>
>>16407764
>So why the fuck not start the car up immediately and drive around.
All you need to do is build up oil pressure then you can drive around.
>Higher rpm from applying gas from an idle or driving wears the engine down.
No it does not, and the reasoning has been explained several times.
This doesn't mean bouncing a cold engine off the rev limiter is a good idea.
>>
>>16400480
a modern car dumps fuel until the engine is up to operating temperature, once it reaches that temp, the computer will trim back the amount of fuel and all the fuel emissions/efficiency shit goes into effect. you waste less fuel letting it idle and warm up than if you just started it up and drove off.

i won't even touch the subject of oil in cold weather.

I had no way to warm it up so I had to just take the hoses off and let it sit there until the next week when it warmed up.
No damage

>>16407823
You realize that this happens regardless of whether you're driving or idling? Look up even the most basic ECU and they will have idle warm up enrichment values. The table for enrichment is a function of coolant temperature in most cases. The target RPM will also be higher no matter what you do.

You don't save fuel by idling.

I feel like no one here has even tried to look at how engine management works because if they did we wouldn't be having these dumb questions.

If it's below freezing you should definitely want it up for least a few minutes

But anything more than 5 minutes is definitely too long
