Haven’t you notice that you have a better fuel mileage when driving on freeways as compared to driving in the city? It is because when you are driving in freeways and highways, you maintain constant speed.

Whereas in city streets, you have to shift gears once in a while and hit the brakes often at the turn of the red light—this wear and tear to you car engine would lead to more fuel consumption.

So does driving 55 save on fuel? Of course, it does. As you maintain constant speed, your engine runs smoothly and would only require less amount of gas (or diesel, if that is what your engine requires).

You surely noticed that even when you stepped off the gas pedal, the car still maintains its speed for a few seconds before it slows down and then you step on it again to speed up. In this case, you save fuel every time you put your feet off the gas.

Experts say that, depending on your car type and how well it is maintained, you can save up to 17 percent of gas consumption when you maintain your speed at 55 miles per hour.

Most motorists hit the 65 to 70 miles per hour mark but at these speeds they will surely spend 10 percent more compared to limiting your speed to 55.

Driving can really be fun, but with the recent prices of oil shooting up, motorists should take into consideration the economics of petroleum products.

Now that you are aware of these things, you no longer have to wonder whether driving 55 does save on fuel.
