1. Don't speed- speeding is a costly habit.  Gas mileage rapidly reduces when driving over 60 mph.

2. Be trip efficient- running many errands in one trip may allow you to drive fewer miles.  Several different trips can use twice as much gas especially when taken from a cold start.

3. Less is more- the more weight in yoru care causes a drop in fuel efficiency.  Also, avoid carrying items on the roof of your vehicle as it hinders its aerodynamics and can cut mileage up to 5%.

4. Cut back on idling- idling gets 0mpg and the larger the engine the more gas being wasted. 

5. Be steady- practice using cruise control, as it can improve mileage by maintaining a steady speed.  Rapid acceleration and braking can lower efficiency by at least 33%.
