Neglecting regular maintenance (regular service) such as oil changes, air filter replacements, and spark plug checks can lead to reduced mileage.
Under-inflated tires can increase rolling resistance, resulting in a decrease in fuel efficiency.
Rapid acceleration, hard braking, and speeding can significantly lower mileage.
Driving with roof racks, open windows, or sunroofs can increase aerodynamic drag and reduce mileage.
When spark plugs are dirty or worn, they can become less efficient at igniting the fuel, which can lead to a decrease in mileage.
Dirty or clogged fuel injectors can disrupt the fuel flow, causing inefficient combustion and reduced mileage.
Extra weight from carrying heavy loads or unnecessary items in the car can reduce fuel efficiency.
Excessive idling wastes fuel without moving the car, reducing overall mileage.
