Track and compare your MPG with Fuelly
If you can get your friends to start using Fuelly then you'll have more of an incentive to track your gas mileage and be fuel efficient since we all seem to enjoy a little competition. You may find out some interesting stats about your friend's fuel usage while using Fuelly. While I have a fuel efficient car, I tend to drive like I'm trying to put out a fire somewhere while my friends with bigger vehicles are known to drive more like a 90 year old out for a Sunday drive. I can't wait to see who is getting more for their money.
I'm going to take Fuelly for a spin today when I fill up my car, I have fallen behind in my usage of Fuel Frog partly because I am lazy and partly because I couldn't remember the format for tracking it by text message. The competitive angle of Fuelly may be just what I need to stick with tracking my fuel cost and usage better and figuring out how to best budget for my gas needs. No matter how you track your gas consumption doing so is an easy way to empower yourself to watch your finances.
