When you create your account, you'll be asked for the "Start Miles". It's important that you follow this part of the instructions carefully, as doing so is important for accuracy and consistency when it comes to knowing the MPG you are getting.

The next time you do a fuel fillup, the miles on your car at the time of your fillup are your start miles. Enter that number where you are asked for "Start Miles:" at the registration form.

Very Important.
In order to properly monitor your MPG, every fillup must be one where you top off the tank. To be consistent, it is best to have the automatic fuel shutoff at the pump determine how much gas you buy. In other words, if you are in the habit of filling up a given dollar amount then you'll have to change your ways; otherwise the WebCars! Auto | Fuel Log will not work out for you.

After you have a few fillups entered, you will be able to see what kind of MPG you are getting. Click on "REPORT" and you'll see the your last five fillups along with the statistics (MPG included) for all your fuel fillups. If you want to review your entire log, click on "LISTING". From the listing page you'll be able to delete or change any entry.
At the listing page, clicking on the icon will delete the entry and clicking on the will bring you to a page where the entry can be edited.

The WebCars! Auto | Fuel Log can also track maintenance, oil changes and repairs. You can review those entries on the "LISTING" page.

Data for the WebCars! Auto | Fuel Log, including fuel fillups, maintenance, oil changes and repairs is entered in the NEW ENTRY page.

There is a PRINTOUT page where you can get print a form that you can use to record your fuel fillups to be entered later.

The NEW ENTRY page has a "Notes" field which can help you learn more about learn why your MPG is what it is. For example, if you think your car is running poorly, enter your observations in the "Notes" area. Should your MPG fall off at the same time, you know have some good information to show the mechanic when you have the car serviced. Also worth noting: when you do anything that can affect your mileage, such as long highway journeys that can produce better than normal MPG.

A drop in fuel economy is a sign that something may be wrong with your car. A good example of this is if the catalytic convertor starts to go bad you will see this reflected in reduced MPG. This is where the WebCars! Auto | Fuel Log is especially useful.
