ok, just updated the SMS system so you can specify a partial fuel-up. You can add a "p" without a space to your gallons/liters to specify that the fuel-up is a partial. So if you went 100 miles, it cost $3.00/gallon, and you only put in 5 gallons, it would look like this:
100 3.00 5p [notes]
Just keep in mind you need the "p" added to your fuel volume with no space. If you have a space in there, the "p" will just be added to your notes for that fuel-up.
