Does a Roaring Engine During Startup Damage the Car?
1 Answers
Car roaring during startup damages the car. Reasons for car roaring: During the first few seconds after startup, the engine's instantaneous speed exceeds 1000 RPM, and the upper part of the cylinders is in a state of direct metal-to-metal friction without lubrication, which can significantly impact the car. Consequences of roaring during startup: Operating the engine without sufficient lubrication increases component wear. Especially when the car has been parked overnight, and the engine is started cold in the morning—idle speed hasn't yet dropped to normal levels. In this cold state, the engine oil is still in the oil pan and takes several minutes to circulate and properly lubricate the engine.
