How long should a car idle to warm up after being parked?

If the car hasn't been driven for over a month, it's advisable to let it idle for warming up, but only for about ten seconds before shifting into gear and driving. If the vehicle has been left unused for an extended period, it's recommended to change the engine oil before using it again. Engine oil left in the oil pan for a long time can oxidize and deteriorate. Continuing to use the car without changing the oil can accelerate engine wear. More details are as follows: 1. Many car owners have the habit of idling to warm up the car, which is actually not a good practice. Idling only increases fuel consumption and exhaust emissions. 2. For fuel-injected engines, idling to warm up is completely unnecessary. The correct way is to start the engine, shift into gear, and drive immediately, just avoid running the engine at excessively high RPMs at the beginning. 3. Shifting into gear and driving right after starting the engine also helps the transmission oil reach its normal operating temperature quickly, reducing transmission wear. Driving immediately after starting increases the engine load, speeding up the warming process. 4. Regular oil changes are essential in daily car use. Over time, engine oil loses its lubricating properties, and prolonged use without changing can worsen engine wear. Always replace the oil filter with every oil change, and ensure to choose genuine products from reputable brands when purchasing oil filters.
