Does a car burn more gas with the lights on?

The overall consumption of gasoline does not depend on whether or not the engine is running while the lights are on. This is because the energy consumed by the battery when the engine is not running is restored when the engine runs.

Does it waste more gas to idle or turn off and on?

Contrary to popular belief, restarting your car does not burn more fuel than leaving it idling. In fact, idling for just 10 seconds wastes more gas than restarting the engine. Warm up your engine by driving it, not by idling. Today's electronic engines do not need to warm up, even in winter.

Does turning your car off at lights save gas?

Unless you drive a vintage, carburetor-equipped vehicle, you'll save fuel and reduce carbon dioxide emissions by turning it off. Some drivers think that idling uses less fuel than restarting, but our research has found that drivers save fuel and reduce emissions by shutting down for stops as brief as 10 seconds.

What will reduce fuel consumption?

The most impactful way to reduce fuel consumption is to simply drive your car less. Drive your car only when you really need to. If you only need to travel a few blocks, consider walking or even riding a bicycle. Not only will you save money at the pump, but the exercise will also certainly do you some good.
