warming up your car is bad???...Huh??

[jonnyk]

Warmup is a critical process to ensuring the metals in your engine are lubricated and heated up enough so that the clearances are where they should be. NEVER RUN AN ENGINE HARD THAT IS COLD. You will break more stuff this way that just about any other. The minute idle, and then very EASY driving is a good idea if you need to get moving right away, until the temp comes up to operating range.
