Well, I did it this morning. I keyed in every gas receipt I have for the truck. It looks like I am only missing one.
I have some interesting stats from this. I have spent over $2600 for nearly 1000 gallons of gas. I am averaging 22 MPG.
The cheapest I have paid for gas is $2.54 and the most expensive is $3.15.
My goal for this is to see if I can correlate better gas mileage to certain gas stations. Part of doing this will be to import driving habbits from my GPS data logger. Another project for another day.
