- Dump the junk in the trunk: Before hitting the road do your best to keep your trunk’s haul light. You can save up to $.07 per gallon for every hundred pounds of weight you remove, so pack only the necessities!
- Raise the roof?: Traveling with a fully-loaded roof rack can not only slow you down, but also decrease your fuel efficiency by five percent, according to the U.S. Department of Energy. By stowing bulkier items in the trunk, you can add a sense of ease to your car’s aerodynamics, as well as its gas tank.
