Even in the summer, I start the car, then put on my seatbelt, adjust the vents if needed, music, etc... then drive. It gives the car a good 30-45 seconds to get the oil circulating. Even then, I don't go over 3k until it's warmed up to the normal coolant mark.

In the winter, I generally follow the same... except I may let it idle for a minute or two. If I do have to scrape anything off, I will start the car first, then scrape, allowing it to warm up. Usually takes 5-10 minutes.

Either way, I WILL NOT floor it until it's been completely warm for 5 minutes or more. Just a personal thing. My roommate in college would always leave at 8am for class, even in sub zero temps and floor it up the street without warming it up at all. The Buick Regal broke a rod or something.. bearings maybe, not totally sure. Either way, the engine was toast and needed rebuilt... so he dumped it. It only had around 125k... which isn't a ton. I suspect him not letting it warm up like that over a period of years didn't help.

I start driving as soon as the air pump turns off which is about 10 seconds or so after I start the car. I keep it under 3,000rpm and no more than 50% throttle for the first 10-15 minutes in the Summer and no less than 15 minutes in the Winter. Oil warms up slower than coolant so just because your temperature needle stopped moving, doesn't mean it's safe to start flooring it.

I always let it warm up for about 5 mins before I drive off, every time I get in.

In Dubai the engine never really gets a change to get cold though so engine wear from start up isn't bad in comparison to some places?

I admit, getting a kick out of these replies about letting it warm up when its really cold out, 20 or 30F ABOVE zero. I give mine a little idle time starting around zero to 10 below, and that is more to avoid death by the passengers than anything else.

The bigger problem is that the transmission turns into a block of solid ice at extreme cold temps. You have to drive it like a non-synchro truck through the first couple gears. A little warm up time helps that somewhat, as there are trans parts spinning even idling in neutral.

I've noticed a loud whining/ whistling noise right after starting my engine in cold weather (~10F) lately.

Anyone know what this is?

And to stay on topic: I've gathered with some research that the best way to warm up a car is actually to drive it. Of course you don't redline or race your engine. but drive it normally at around 2000 rpm for a few minutes, that will get the oils flowing and warming up quicker than just letting the car idle. (Save fuel too)

I let the car idle for 20-30 secs now that it's getting cold, but during the warmer months I drive it as soon as I start the engine.

I'm more bothered by the sticky shifter during the colder months than what'll happen if I don't warm up the engine.

I wait for the blue light to go off before i move. In summer might take a minute and in witner it might take 10 but either way ill wait. I have to believe it saves gas rather then driving cold.

Saves gas if you idle for 10 minutes?

You get zero miles to the gallon while idling. Which is much worse than the gas mileage driving those couple minutes before the 02 sensor and oil warm up.

Yes, i totally understand however think of how low the mpgs are during a cold-start-and-go. The mpgs for idling are 0mpg i agree, but i think if your car is trying to warm up while driving, not only does it have to warm up the cold fluids and engine but now it has to compensate for the heat loss due to forced convection from the air rushing around it. By letting car warm up during idle, the air around the engine is not sucking as much energy from the engine. Its kind of like youre investing gas to save some during the commute.

plus i have a long drive so it might be not help if you take short trips as your car may not hit optimal temp before you arrive.

I have no hard evidence if im right or not. just my 2 cents.

The car warms up WAY faster when you're driving. I have a 1.6 mile commute to work, its warm by the time I get out of the parking garage and up the first hill on the coldest weather we've had this year.

With a 4EAT if you do not warm up a minute, you can feel a hesitation to shift into third gear because the AT temp is low. But I rarely warm it up when on the move, only at home if I have time. 10 years no issues.

I think its the alternator that makes this whine. That or the cylinders not having any oil right away since its basically jelly. I get the same thing.

I usually let my car warm up a minute or so before driving in the cold, just to get the fluids moving and my commute is so short I want to get a little more of the condensation out.

Cars really don't use much gas at idle... Sure, you're getting 0MPG, but you're still not using much fuel. Everything does warm up faster if you drive, but personally, I'd rather get a remote starter and let it idle for a minute or 2 before I start driving. It's definitely not going to harm anything, and if you can't afford the gas to idle for 2 minutes, maybe you should buy a honda.

Right, but the people who think they can let it idle for 10 minutes and then start romping on it right away are wrong.

Does your car have a carburetor?

It's better to

Let your car warm under a load rather than at a standstil

unless you have piston slap on cold starts. Load is what makes me have to hear it.

Specifically in my car, when 100% cold, anything above 1.5 rpm makes the piston slap noise audible. The idle speed is <1,000 rpm, so sitting for 5-10 min will allow the motor to warm up enough to drive away slowly until fully warm, without slapping.

Load doesn't cause the slap, it just allows you to hear it.

That's what I meant by "happen" but I couldn't think of a better way to say it.

thanks man. I just know it has something to do wit the cold. the car is like brand new and literally only started happening when it got cold. also it only lasts about 5 seconds.
