As the summer vacation season approaches, the prices on the gas marquee begin looming, posing a threat to potential summer fun.  But a variety of Energy Department tools can help you save money and use less gasoline when you travel. offers a number of ways to help you keep down fuel costs.  Properly inflating your tires and removing excess weight from your vehicle before you go can increase your potential fuel economy.  Once you're on the road, observing the speed limit can make a big difference—every five miles you drive above 50 mph is like paying an extra $0.24/gallon for gas! 

To estimate what your fuel costs may be, you can use's Trip Calculator.  After you enter your starting point and destination, you can run the cost for one car or compare the fuel costs of up to three cars at a time.  For each car, the tool shows the miles per gallon (MPG), fuel used, and fuel cost on that specific route.  As vehicles differ in their city and highway mileage, the route you drive can make quite a difference! You can further customize your results by entering in local fuel costs or adjusting the MPG if you know you are a very fuel efficient (or inefficient!) driver.
