Warming Up Car in Idle State
My car is a 2004 Honda Accord LX at 110K miles. I have often heard from others that after turning on the ignition, it is a good practice to warm up the car engine in idle state before starting to drive it. They advice to do this at the beginning of each day regardless of considering the outside temperature issue. Meanwhile, I have heard the other side of the story as well like this warming up in idle condition actually harms the engine. What is the real fact? Even if it is good for the engine, for how long should I warm up the car in idle state before starting to drive it?
