Do Cars Need to Warm Up in Winter?
1 Answers
Winter cars need to warm up, the main reason is: after the car has been parked for a long time, the engine oil flows back to the oil pan at the bottom of the engine. After the car is started, the upper part of the engine is in a state without oil and lacks lubrication. It takes about 30 seconds after starting for the oil pump to operate and deliver oil to the engine components that need lubrication, such as pistons, connecting rods, and crankshafts. The correct way to warm up the car: the engine speed should not exceed 3000 to 3500 revolutions per minute, maintain 2000 revolutions, and wait for the engine temperature to rise to the normal operating temperature (which takes 3 to 5 minutes), then you can resume normal driving.
