Your first fuel-up on FuelGauges can sometimes be confusing if you are not familiar with tracking your truck's fuel mileage.

Here are some Tips on collecting fuel-up information

Getting started the easy way: 

1. Do not enter the information for the first fuel-up into MyGauges. The only part of that fuel-up you'll use is the odometer reading.
2. After fueling up a second time: take the first unentered fuel-up and use it's odometer reading for your odometer start (OD Start) and the second fueling's odometer reading for your odometer end (OD End).
3. Complete the fuel-up form with as many details as possible. The more information you have to refer back to  the better.

Note: The more accurate information you add the better your results when reviewing your fuel mileage.
