What Causes a Sudden Increase in Fuel Consumption for Automatic Transmission Cars?

[SanNora]

Automatic transmission cars experiencing a sudden increase in fuel consumption may primarily be due to insufficient tire pressure. Related information: 1. Introduction: Tire pressure, strictly speaking, refers to the air pressure inside the tire. There is a standard tire pressure indicator on the rear of the driver's side door, which indicates the pressure when the tire is cold, i.e., after the car has been parked for at least three hours or driven no more than 1.6km. Measuring tire pressure when the tire is cold yields the most accurate results. 2. Expansion: Air pressure is the lifeline of a tire; both too high and too low pressure can shorten the tire's lifespan. Low pressure increases tire body deformation, making the tire side prone to cracks, and causes flexing movement, leading to excessive heat generation, promoting rubber aging, fatigue of the cord fabric layer, and breakage of the cord wires. It also increases the tire's contact area with the ground, accelerating wear on the tire shoulders.
