Which driving technique can improve your vehicle's fuel economy?

Avoiding unnecessary idling is beneficial for improving your vehicle's fuel economy because idling consumes fuel without providing any distance traveled. When a vehicle is idling, the engine is running, but the car isn't moving, leading to wasted fuel. By minimizing instances of idling, such as turning off the engine when parked or waiting for extended periods, drivers can conserve fuel and improve efficiency.

In contrast, increasing speed aggressively generally leads to higher fuel consumption. Using air conditioning constantly can also lead to a decrease in fuel economy, as it puts additional load on the engine. Lastly, driving with wide turns does not directly contribute to fuel efficiency and could potentially lead to more unnecessary acceleration and braking, which can also be detrimental to fuel economy. Therefore, avoiding unnecessary idling stands out as the most effective technique for improving fuel efficiency.
