Minimizing Idling and Avoiding Rapid Acceleration

Idling consumes half a gallon to a full gallon of fuel every hour. That’s ten to twenty ounces every ten minutes with no travel benefit. Modern vehicles are designed for efficient restarting.

If you’ll be stopped for more than a minute, turn off your engine. Restarting uses less fuel than prolonged idling. This simple habit can save a lot of fuel over time.

Avoid rapid acceleration, sometimes called “jackrabbit starts.” This demands a lot of power from your engine quickly. Smooth, gradual acceleration uses far less fuel and reduces vehicle strain.

Adopt a mindful driving style that prioritizes smooth transitions. Anticipate traffic patterns to maintain steady speeds. These habits significantly boost your vehicle’s fuel efficiency.
