Yesterday I posted how you can use Twitter to track your gas mileage. Today I am going to give you a list of 3 more websites that you can use to track your gas mileage.
1) Fuelly.com 
The website I use to track my gas mileage and fuel economy is Fuelly.com. I have been using the website for over year and like it because it has an iPhone optimized website that I can use on my iPhone right after I have filled up my car.
Here is a demo of Fuelly.com:
Using Fuelly and setting up an account is very easy.
Step 1: Create an account
Enter your email address, password, pick a username, and enter your full name.
Step 2: Add a vehicle
Step 3: Update your profile. You don’t have to do this to start using Fuelly.com
Step 4: Add a fuel-up
Enter the odometer reading on your car and the gallons. Entering the price per gallon is optional.
Fuelly.com has a mobile website that can be accessed from your mobile phone. The mobile site can be accessed at: http://m.fuelly.com/
One of the really nice things about Fuelly.com is that you can brownse among makes and models of cars.
You can also compare different makes and models, years, engine types, and configurations (this is especially useful if you’re shopping for a new vehicle and want to see real-world economy figures).
2) MPGTune.com
MPGTune.com is free to use. The way it works is that you have to print out your gas receipt, write down your odometer reading, and then enter the information online. That fact that they don’t have a mobile site is a deal breaker for me.
3) FuelClinic.com
FuelClinic works like MPGTune.com. Print out your receipt, record your odometer reading, and then enter the information the next time you are at your computer.
This might be a good solution for some, but for me, it is much easier to enter the information on my iPhone while I am at the pump.
Now that you track your gas mileage and fuel economy, you need to find the cheapest gas.
GasBuddy helps you find cheap gas prices in different US cities. You can discover stations which sell gas at a cheaper rate and also check the gas price maps and historical price charts. GasBuddy also has a mobile website that can be accessed at http://gasbuddytogo.com
MSN Autos can also help you find cheap gas.
