When I brought a new car, I learned that paying for my own gasoline is very expensive! I learned a few tricks from then as to how to save fuel. The first trick is to brake only when necessary, that means you have to stay very alert while driving. The next trick is to get your tires pumped up. The more smooth they are the better they roll on their own due to inertia and your car does not require to apply pressure for the wheels to roll.
