starting your car first time in 2 days its 80* outside should you still let your car warm up?

Answer 1

All computer controlled cars nowadays don't need to "warm up," just give time for the oil to circulate and the engine ( 30sec-1 min) and your good to go.

Answer 2

My definition of warm up is start the car and let the oil circulate the engine at idle speed for 30 seconds. Then start driving while keeping RPM under 3000 until the car reaches the operating temperature. Old days of running engine for 5 minutes is long gone.

Answer 3

ok this is a tricky question but here goes-- the engine is designed for a specific operating temp usually 150-225 warming up an engine is done to get the oil everywhere inside the engine without air pockets and to coat the walls of the cylinder. As the engine warms up every part inside the engine expands -- like heating a stuck nut to remove it from a bolt-- but a motor gets tighter as it heats up not looser. warming up an engine cuts down on the wear inside of the engine. Driving on without warming it up-- current motors is about 1 min @ 80*-- puts a load on those parts when they haven't reached design spec and results in more wear. The most wear an engine gets is during start up (75-80%) Not to mention that the engine polutes more due to the incorrect cylinder temp (back to design)-- So yes you should warm up the engine. Only the length of time changes due to ambiant temp (air temp) a good example is in desiels you see them warm up no matter what. Now don't ask me what i do cause i ain't gonna tell-- hope this helps

Answer 4

Although it is true that with modern cars you really don't have to let them warm up before you drive, I still do, just a little bit. Especially if I haven't driven my car in a few days, I will start it up, back out of my garage into my driveway, and wait for about 30 seconds before I drive. This may not be needed, but it gives me piece of mind that by that time oil is flowing throughout my whole engine. Even with modern cars, it is still a scientifically proven fact that cars get very very poor gas mileage when driven cold, I believe that average V-6 engine gets about 6-10mpg when driven cold. So although it is not neccesarry, I would still recommend letting it idle for at least 10-20 seconds before driving. In my Accord I have a navigation system, and if I wait until that loads up, I know my car is warmed up enough to drive.
Hope this helps.

Answer 5

Not in my opinion. Most newer cars are made for start and go as they will adjust the fuel mix accordingly.
The real old cars used a manual choke and it helped to let them warm up so the choke could be released and it run OK.

Answer 6

it has nothing to do with the choak or anything. u should give the car a second or two to let the oil pump throught the engine. most people will start their car and go or rev the engine. in the long run it will damage the car. for the simple reason when they rev up or go there is that few seconds there is no lubercation in the engine.

Answer 7

There is NO time you'd let a car warm up with a modern car. By the time you have your mirror adjusted and your seat belt on, it's time to drive.

Answer 8

It's not really necessary to warm it up, as such. Just start it up and let oil start flowing through the engine, easy on the gas for a couple of minutes and you'll be OK.

Answer 9

as soon as all the idiot lights on the dash goes through the checklist and go out it's time to drive with these newer cars, no need to warm them up.

Answer 10

if your planning on driving it less than 100,000 miles before you sell it then forget about warming it up
