You need to warm up your car in summer, but idling is unnecessary. Here are the specifics about warming up: Benefits of warming up: The biggest advantage of warming up is avoiding cold-engine wear. When starting the engine after it has been sitting overnight, the upper part of the engine lacks lubrication. It takes about 30 seconds after starting for the oil to reach critical components like the pistons, connecting rods, and crankshaft. Precautions for warming up: Idling to warm up isn't better the longer it lasts. Avoid revving the engine aggressively while idling. It's best to drive gently at about 40 km/h for the first 2-4 kilometers. After starting, wait about 30 seconds, then drive a short distance at low speed and in low gear to lubricate the transmission, differential, and wheel bearings. Once the engine reaches normal operating temperature, you can drive normally.
