小心喔!!!熱車時間越長引擎掛得越快早上要不要熱車不知熱與不熱有沒有差別.......

其實這個觀念是錯誤的；熱車時間愈長，你的引擎掛得愈早!相信各位若翻開你的車主使用手冊，

熱車，不僅增加引擎磨損的機率，也會使得積碳現象發生，並且將造成機油的快速酸性劣化，縮短機油的壽命。# ^/ ?. k( O( B* X
事實上停車時的熱車通常都只能讓引擎的溫度提高，但其他各機件卻仍然處在冷車狀態，

驅動系統的熱車就比引擎熱車來得重要，但是驅動系統若你不行駛它是不會熱的。

但你仍不能大腳油門，因為引擎及驅動系統都尚未到達正常的工作溫度，你應該先讓引擎在2000轉之內慢慢地行駛，待水溫到達正常的溫度時才可大腳油門。

please do more research b4 you are gonnd say sth stupid like this

But the turth is I bleive that you are from some southern asia which means that you wount have a snow in the winter that's why you can't really understand 4 {% w3 O% n& T1 D) @. j; A
the reason why
) @" K9 Q; P. l7 X8 m公仔箱論壇since you got super cold weather outside (-0C or below) your radiator fluid and engine oil is not really at the best working condition. They are more thick than normal that's y you siad about the emission will make sense but not the reason that you are giving above , S3 i: r8 s" v7 a( H! B% x
also If you keep driving yuor car out in a slow speed it will be a better idea in most asia countries but not even to anywhere that will snow in the winter& N& p! u. b$ m, c2 g5 L
becasue you are actually startign to let the wind to blow at your radiator to cool down your radiator fluid (which is very cold already) then it will actually takes you more time to heat up the engine and make it burn more gas and more emission to be called as pollition

totally agreed .. it's impossible to drive in the winter if u don't heat up ur car for awhile .. especially if u don't have indoor parking

i think the original poster is right. there is no need to idle after starting the car. just wait for 5 seconds after the rpm is stable then you are all set to go.. just take it easy with the car for the first few miles..  i used to live in Boston and i drove there for 3 years.
