http://www.washingtonpost.com/blogs...hat-you-need-to-idle-your-car-before-driving/ Only carburetors needed the warmup. I dont think most people have a carburetor in their vehicle. Driving the car actually warms up the engine better than idling. I always wondered that. Most people will be driving slow first anyways because they dont get onto the highway right away anyways. Sitting there and idling the engine is just wasting fuel and not getting you anywhere. In fact all it does is make the climate change even more. People are idling all the time and it just pumps out that greenhouse gas. So spread the word, dont warm up your cars, is not necessary, and stop polluting. Bye bye, and have a happy new year bishes.
