10. Avoid Excessive Idling
This suggestion goes without saying. Run the engine less and burn less fuel, it’s a simple one-to-one idea. Waiting for your kids at the bus stop? Rather than idling just to power the radio click it over to accessory mode. Stuck in a long line at the bank drive through? Try switching the car off to save a few precious drops. Every little bit helps.
Vehicles with start/stop systems build on this idea by killing the engine when you’re halted and seamlessly (usually) restarting it when forward movement is called for once again. If you’re shopping for a new ride, see if you can get one with this technology; it can dramatically improve efficiency in heavy traffic and urban conditions.
