Question:
I have a 2007 Chevy Cobalt and I was told it is hard to let it warm up in the morning before I drive it. I don't believe them, but of course curiosity killed the cat. Is it really hard on my car to let it warm up?
Tire question for my 1984 Mercedes 300 SD?
My friend said to just start it up and drive it (with care) until it warms up. Is this true?

letting it warm up is one of the best things you can do for your car.engine block,pistons, valves and cylinder heads are made from different types and differently hardened metals.its best to let engine reach normal operating temp before driving.most people do not do this though.ask your local ase certified tech,not a shade tree grease monkey.A couple of minutes at idle is all you need to get the motor oil circulating through the engine. After that just drive away normally.
my catylic converter is plugged up and everytime i try to start my car up it won't start?
I say 1 to 2 min to let the oil circulate.After changing brake pads, the car brakes seem to be activated all the time?
Your friend is right. It takes longer to warm up when it's just idling and that means more wear on the engine.How do i get scratches off my car window?
Ah the chevy midgets, cute cars really. . .no it's not hard on your car to just start it. you're just using up gas. kinda like sitting at a stop light or waiting in line at burger king. you don't really HAVE to wait for it to warm up though, just drive it - it's a car. . .unless somethings wrong with it you should be fine. and if it's slow to shift or is having trouble braking at times it could be the weather.98 Malibu cig. lighter and accessory outlet fuse location..?
my dad is a mechanic and he always let my car worm up ..i even asked him if it was bad for the car and he yelled "of course its not!!" so i would think its just fine.By not letting in warm up prior to take off you are shortening the life of the engine considerably. Driving the engine cold puts stress on the components and, the primary reason to let it warm up, the oil is like jello until the engine is warm thus providing very little lubrication to the engine.
But by all means destroy the car, you will enjoy the repair bills.
I drive a 44 jeep (the genuine one) and never warm it up except in a realy cold winter (0°F and below).
A normal car should not need warm up before driving. Driving defensively at start (and therafter most welcome) sounds like a good idea.
There is rumour (at least in europe) that letting the motor running for warming up purpose is not allowed. The environment and so.
turbo chargers/super chargers?
Yes your friend is correct. Most modern cars do not need to sit and run to get warmed up. It wouldn't hurt to warm it for a minute or so, but any longer than that and you are just wasting gas. The modern oils that have been developed really decrease the time it takes for the oil to get pumped all around the engine. Also, don't race your engine in the first few minutes it is being run.have five.1/2honda on a aircompresor will not stay running why?
i know if it is really cold out you should let it warm up.other than that just start the car and wait about 15 seconds .An 83 Honda Accord Automatic. Why does it cut out going uphill in low, but is o.k. in normal drive?
You're going to get lots of different answers on this. In very cold clilmates, people allow their cars to warm up before operating them. If its really cold, allowing the engine etc. to operate a few minutes will not harm you vehicle. Getting into a really cold car and operating it at highways speeds without a warm up is harmful. All the lubricants and fluids in the vehicle should have a little time to warm up. If warming up vehicles was harmful, there would be lots of junk cars in the Dakotas, Montana, Idaho, Wyoming, etc.The worst thing to do is drive a really cold car a short distance and stop. This doesn't allow the engine etc. to get up to normal temperatures and will cause significant moisture buildup in the engine and exhaust systems. Not good.
Good luck.

The sooner you can start driving the car the better. Just drive gently until fully warmed up, i.e. avoid excessive revs.equipments used for cement making?
The longer you let the car idle, before driving, the more the oil will become diluted by a gas mixture. All cars need a richer mixture to start (more gas and less air). The sooner you drive the car, the sooner the car will warm up and be running on a normal mixture.
Obviously in the winter you need to let the car warm up for a minute or two, but it's best to keep it to a minimum for the reasons stated above and the fact that a richer mixture is creating more air pollution.

Letting a car run is only harmfull for the environement. You could let it run all day if you wanted to.my car RHS indicator light flashes too fast - how can I fix it?
Start ups are the thing here. Since the oil is in the oil pan, there is no oil for lubrication for a brief period of time. Letting the car warm does not hurt anything and where you live, it will actually help. At very cold tempatures, oil is very thick and letting the engine run a bit will warm it up and thin out the oil.More Questions & Answers ...
