There are many factors that effect the fuel efficiency of an automobile. Many factors are related to the engine and the engineering of the components of an engine in an effort to achieve the maximum output for the minimum input. Much of these efficiencies are gained through weight reductions, electronic monitoring sensors, gearing and technology that allows the engine to produce less output when the automobile does not need it. (i.e. high speeds, or idling). Other factors that are maintenance based which can make a car more fuel efficient is ensuring the automobile's tires are properly inflated, ensuring that the oil is changed in accordance with the manufacturer's recommendations, ensuring the exhaust system is free of blockage and all components are free flowing, making sure your car's oxygen sensors are working properly (fuel air mixture can drastically reduce fuel efficiency) and also driving the automobile in a manner that promotes the best fuel efficiency. Quickly accelerating, driving at very high speeds, and heavy stop and go conditions will all decrease the car's fuel efficiency.
