What can cause excessive gasoline consumption in a vehicle?

Excessive gasoline consumption in a vehicle can result from multiple factors, but one particularly significant cause is underinflated tires combined with poor wheel alignment. Underinflated tires require more effort to move the vehicle, leading to increased rolling resistance. This additional resistance forces the engine to consume more fuel to maintain speed. Similarly, poor wheel alignment can cause the vehicle to drag or pull to one side, which also increases rolling resistance and fuel consumption as the engine works harder to keep the vehicle moving in a straight line.

When both of these issues occur simultaneously, they can significantly exacerbate fuel inefficiency. Addressing these problems through regular tire maintenance and alignment checks can help improve fuel economy and reduce overall gasoline consumption.
