STAY OFF THE BRAKES
Leave at least one car length of space per 10 mph of your speed in front of you, and anticipate traffic ahead of you. Don’t waste fuel by rushing up to a red light. Braking wastes gas and wears out your brakes.
At speeds over 40 mph, fuel mileage decreases as speed increases.
Don’t haul around unnecessary weight in your car. Empty trunk and remove excess items from your car. Less vehicle weight means higher gas mileage.
