Like Jerry says "some people drive their cars like a light switch", meaning they are all in the gas or all in the brake. Transitioning from stops to cruising or vise versa has much to do with gas mileage. Temperance while accelerating and developing space between your vehicle and another allows more coasting and less braking hence less accelerating. Also when approaching a stop light begin coasting long before the brakes need to be applied to stop. The #1 way to increase gas mileage is to have your tires properly inflated. Don't buy any snake oil mileage gimmicks. We did a lot of work a few years ago when people bought the airnado devices which supposedly would swirl the air to help mix with the gas in the engine. What a total rip off. The #2 rip off was the magnets that went around the fuel lines to allegedly make the hydrocarbons molecules equally disperse thus making combustion more efficient.
We like to offer tips for our clients and readers. Little actions we take usng our vehicle will help save you money in the long run. Gas is at a good price right now however, I think we all realize prices will not remain low forever.
