What Damage Does Starting in Third Gear Cause to a Car?

[Harmony]

Starting a car in third gear is theoretically possible, but the likelihood of stalling is quite high, making it practically difficult. Essentially, only drivers unfamiliar with cars would attempt starting in third gear, as it requires much tighter coordination between the clutch, throttle, and brake. Often, the car stalls before the clutch even reaches the semi-engaged state. Below are relevant details: Content 1: The engine speed drops instantaneously during vehicle startup, causing the engine to sputter and nearly stall. This is a severe case of lugging, which is highly detrimental to the engine. Content 2: An overly rich air-fuel mixture is introduced. If the fuel proportion in the mixture is too high, the fuel cannot burn completely, adhering to the surfaces of internal engine components and forming carbon deposits under high temperatures. Besides carbon buildup, prolonged use of an overly rich mixture can also dilute the engine oil. Similar to oil dilution caused by blow-by, the excess fuel in the mixture can seep through the gaps in the piston rings into the oil chamber, thereby compromising the lubrication effectiveness of the oil.
