Everything else is calculated;Miles, cost/gal, tankful mpg. I also have column to input where I filled up, and an extra column for notes, for things like when you changed an air filter, or anything else that could potentially affect mpg.
I just write the odometer reading on the gas receipt from the pay at the pump. I also reset the trip odometer at that time. If you don't do a complete fillup, say you are needing gas real bad and the only station around is too high, and you just pump in a couple of gallons, just add that amount to your next complete fillup and everything is good for calculations.
I have a seperate spreadsheet page for each calendar year. At the top I have cells that keep a running total of fuel used, total $ spent on gas, total miles driven, high, low, and avg fuel cost and ave mpg, all for that calendar year. This turns out to be some of the more interesting data over the years.
I do the same with a spreadsheet. I even split out gas tax so I know what part of a fillup is tax. I have Excel on my phone, so I just enter the numbers while it is filling. Then I just enter the gallons when finished. I did this from the first fillup to when I crashed with 15,600 miles. Overall mileage was 31.5 with 70% highway 30% city. Highway driving was around 70 and moderate to aggreesive city driving.
I enter any money spent on the car whether it is maintenance or loan or accessories etc. Here is a breakdown of costs.
