如果车放户外。
有没有人从来不热车,直接跑路的?即使-30度。
看来热一两分钟还是必要的。
今天早晨这种-28度温度不热车就上路是会损伤发动机的。具体说起来比较复杂,因为涉及到润滑油(5w30)及油膜(film)温度特性,部件热应力,动力学与配合及疲劳性质,发动机计算机控制系统等。不愿花时间多写了,写了你们也不信,就摘一段现成的吧
Certainly, ambient conditions will rule.
If it’s just 10 degrees outside, start your car, let it run for 30 to 60 seconds to get all the fluids moving, then drive off gently. Don’t race the engine or accelerate suddenly.
If it’s extremely icy or foggy, you might have to let your car warm up a bit more to clear the windshield.
And drivers in extremely cold climates will want to give their engines a little more time to warm up, if only because moving off too quickly if it’s, say, 20 degrees below zero outside, can actually damage your engine.
If it's below zero, try to limit your warm up to no more than five minutes before you drive off into the frozen wilderness.

你听他们忽悠开了十九年,从来没问题。只是启动慢一点儿。现在的车从新开到旧(十二年新),开了17万,正想试一试小日本的极限---到底红旗能打多久?
听了各位建议,以后老老实实地热完车在开!谢谢!
