Does prolonged idling have any impact on the car?

[Gama]

Prolonged idling does have an impact on the car, with the main effects being: 1. Increased fuel consumption; 2. More likely to form carbon deposits; 3. Can easily clog fuel injectors or even cause piston rings to seize; 4. Accelerates engine wear; 5. Worsens engine exhaust emissions, polluting the air. Keeping the car running without moving or accelerating is called stationary idling, where fuel is consumed only to maintain the engine's minimum operational requirements. It is recommended to avoid prolonged idling whenever possible. If you need to wait for more than 5 minutes or an extended period after parking, it is advisable to turn off the engine. If you accidentally leave the car idling overnight, you can drive at high speed for twenty minutes the next day to help expel the carbon deposits.
