Why is it important to warm up our car before we drive it?

Answer 1

when a car starts when it is cold most of the fluid(s) are sitting in the bottom of the motor, and if you have ever seen what molasses looks like in the cold(slow as molasses) that is the (viscocity) of your motor oil. so when the car is started and immidiatly driving the engine has a harder time moving oil to the crucial parts of the motor, and in essance you are putting wear on the motor(more than normal) this is also true for the transmission, heating system. 5 minuites of run time before driving it is adequate.

Answer 2

Does your car have a tachometer? Do you notice the engine speeds up a little when you first start it, then returns to normal? When that happens it is time to drive. Don't let it sit idling and wasting gas. Modern motor oils are thin and reach the engine parts almost immediately, plus it adheres to the insides of the engine and does not run off like old time oils. The engine will also warm up faster under load than while standing. So, my answer is: It is not important or necessary to let it sit and warm up.

Answer 3

When your car sits, the fluids that run the engine settle. Warming up your vehicle for at least a couple minutes before taking off gets the fluids back in circulation throughout the engine which should decrease future engine problems. It's more a maintenance thing. Hope that helps.

Answer 4

It isn't important to idle your engine until it's warm, and it actually causes more wear and tear to the engine to sit there and idle until it gets warm. To get it warmed up quicker, it is best to drive it at moderate speeds shortly after starting the engine until it is warm, then you can drive faster (some manufacturers even say in their owners manual to drive it immediately after starting to avoid unnecessary damage).

Modern engine oil is designed to flow at cold temperatures, that's what the viscosity rating is for. For example, a 5W30 oil reacts like a 5 viscosity rated oil in the cold, and like a 30 viscosity rated oil when warm (the lower the viscosity number, the more freely the oil runs). Also, many people think the W stands for weight, in reality it stands for Winter, or cold rating (5 Winter, 30 summer).

So, it is definitely NOT necessary to warm your engine up to get the oil flowing to the engine parts. As soon as you start it oil is flowing, if it wasn't, it wouldn't matter if you idled or drove it, it would ruin the motor very quickly.

The biggest reason most people warm their engines up is to get heat for comfort. Some do it thinking they are doing good for their engine, not knowing they are doing the exact opposite

Answer 5

Main reason is that tolerances between parts is greater in a cold engine (cold metal contracts). This increases the clearance (gap) between such components as the connecting rod bearings and the crank shaft journals. With a large gap, when the connecting rod changes direction, the force is transfered from one side of the journal to the other and the oil film is broken and allows metal to metal contact resulting in excessive bearing wear.
As the engine warms up, the gap gets smaller, this creates a consistent stronger oil film.
It isn't necessary to warm the engine to normal operating temperature. A warm up for 3 to 5 minutes is sufficient if you avoid hard acceleration for the first few blocks.

Answer 6

They've pretty much answered it but here is my explanation. You need to warm it up so that it circulates the oil and makes the oil more viscose(runny) so that it lubricates better( less friction means longer engine life). Moving parts in your engine will expand with the heat and will have the correct clearances too( less friction means longer engine life)

Answer 7

It is not so much "Warming Up" the car as It is getting the oil circulated through out the engine. It takes approximately 30-45 seconds for the oil in the engine to reach and lubricate all the parts in your motor. So....... if you just jump in........fire it up ..........slam it in gear.........shove your foot down on the gas....and get out on the road............BAMM!!!! you just took about 5000 miles off you engines life.

So let it "warm up" when you start it. your wallet and your car will both love you for it !

Answer 8

Your engine contains numerous shifting metallic aspects that are lubricated by way of oil. This oil drains to the oil pan contained in the bottom of the engine even as the vehicle isn't operating. even as the vehicle starts up chilly it takes awhile for the vehicle to attain commonplace operating temperature and for the oil to flow to each of the shifting aspects. Revving the engine or utilising it above idle speed even as chilly causes untimely positioned on of those metallic aspects that are not getting oil on them which will reason engine failure more effective rapidly. the biggest ingredient to keep in options isn't to race or rev the engine even as first beginning. you are able to honestly rigidity it fairly a lot straight away when you're waiting to keep the rpms round idle speed for the first couple of minutes. desire this helps.

Answer 9

another thing about cold systems is that water will build up in the exhaust system; the water comes from the fuel. if you don't run your system hot enough to burn off the water in the pipes, your exhaust will rust away and put holes in the pipes and muffler.

Answer 10

BCZ ENGINE OIL RUN THROUGH ALL THE PARTS AND EVERY PART IS LUBRICATED BEFORE THE ACTION
