Instead of entering the number of gallons (or liters) purchased, I think it would be useful to be able to enter the total price paid for the fuel and the cost per gallon (liter). Then the program could always accurately figure the number of gallons or liters purchased. Where I live, there are several stations with older pumps with analog gallons readout, and if the # of gallons purchased is not printed on the receipt (as is often the case here) it's tough to get an accurate reading. Thanks.
Not a bad idea. Since I got my Blackberry, I no longer ask for receipts, so when I enter my data, I have to make sure I look back at the fill up and read what I put in. But I typically know that I fill up at a certain amount when I pull in, and I typically remember how much the fill up cost me ($30 is easier to remember than 27.456).
On road trips where I usually fill up a few times (going through canada), I wait till my bank statements show the cost, I add em all up, add up all my miles, and add up all my gallons (3.8L-1gal). I have my own spreadsheet that I input all this into, it gives me price/gal for the trip, which is the figure I have to use for fuelly.
This suggestion would save me a step, and if propose going a step further in allowing a road trip type fuel up, where 5,000 miles is an acceptable value to put in for mileage, or 110 gallons, ect.
