br One of the most effective ways to save gas is to be an ideal driver. It may sound a little far-fetched, but motorists who keep their driving under control and observe the speed limit end up saving more fuel than speed demons prone to fits of road rage. Driving at a steady speed allows the engine to work in a more stable environment. This way, the engine doesn’t guzzle more fuel than it has to. Unnecessary acceleration and abrupt braking waste more gasoline than most drivers realizes. Fuel economy experts say that driving over 60 mph slowly, but surely, reduces a vehicle’s gas mileage.
