This is a great website to use for you to find which gas stations have the lowest prices in your area. Just search gas stations by zipcode!
This is the homepage of MapQuest.
To begin to find how much gas will cost you for your next road trip, you need to click the "Preferences" tab in the upper right corner.
Then click on the "Vehicles" option underneath.
If you already know your car's city and highway gas mileage, then you can plug it into those boxes and skip the next two steps.
But, if you are like most, and do not know the exact mileage, click the "Look up your Car's MPG" link.
This link will direct you to FuelEconomy.gov.
Just enter in the year, make and model of the vehicle of which you want to know the gas mileage.
The next screen will have a list of cars that fit the criteria you entered.
For example, I chose to look up the information for WHSV's station cars - a 2005 Pontiac Vibe.
Once you get to this page, copy down the highway and city miles-per-gallon number. You will need it for the next step.
Go back to the MapQuest website and plug in the information for your vehicle.
Next, choose the type of gas.
Enter in the addresses of your beginning and ending destinations.
The fuel cost will automatically calculate when you hit the "Get Directions" button.
