I seem to remember reading somewhere that with newer cars (that is, from about 1990 on), this is no longer necessary......however I may be wrong.
I never do and my car is going fine..........

Your engine consists of several moving metal parts that are lubricated by oil. This oil drains to the oil pan in the bottom of the engine when the car is not running. When the car starts up cold it takes awhile for the car to reach normal operating temperature and for the oil to circulate to all the moving parts. Revving the engine or driving it above idle speed when cold causes premature wear of these metal parts that aren't getting oil on them which will cause engine failure more quickly. The most important thing to remember is not to race or rev the engine when first starting up. You can actually drive it almost right away if you are able to keep the rpms around idle speed for the first few minutes. Hope this helps.

I work in a garage, and new cars are designed better then what they were in the past. You're susposed to let the car warm up for about 30 seconds, and then start driving in any condition. That way the car warms up as a whole, and theres is less damage to the vehicle. Warming up your car for 5+ minutes is actually harder on your car then driving it. Let the car drop to normal idol and then drive.

Does your vehicle have a tachometer? Do you spot the engine quickens a sprint once you first start up it, then returns to customary? while that happens it's time to tension. do not permit it take a seat idling and dropping gasoline. cutting-part motor oils are skinny and attain the engine factors very nearly in the present day, plus it adheres to the insides of the engine and does not run off like previous time oils. The engine will additionally heat up speedier under load than at the same time as status. So, my answer is: this is not significant or mandatory to allow it take a seat and heat up.

warming up a car is not the best thing for the engine,if your car starts right away then drive off. idling puts pressure on the engine parts from cold,driving off straightaway increases heat and movability in the engine and it will reach a operating temp quicker,therefore lubricating moving parts quicker.and charging the battery up is essential /better whilst moving.

after a car sits all night some of the parts dont hold an oil film for lubrication when you start your car the oil pump picks up oil out of the pan and sends it to your bearings and such so it needs a small amout of time to get there depending on the outside temp. the colder it is the thicker your oil is and thus the longer it takes to lubricate

It will cut out in cold weather if you don't.
