I use that msn tool but I also use the local page associated with gasbuddy.com
. I really like it because, not only does it show where the cheap gas is in my area, I can also use the site to track my fuel purchases and when I enter the information from my receipt it records my mileage. So, for the past year and a half, I can tell you exactly how much I spent and what my mileage was and is. You can record this information for multiple vehicles. Well, I think it's pretty cool anyway.
