    Default use more than 1 fillup

    Gas stations vary greatly in when the filler turns off, in other words some pumps let you put in more fuel than others which makes your calculation inaccurate.

    I would recommend using more than one fillup to calculate gas mileage. If you use 5 or more fillups (and corresponding miles) you get much better accuracy. Here is a link to example calculation:

    Good luck.

    And after you get you MPG calculated you can figure out how much you're spending for every mile you drive!

    Price per gallon / your mpg = how much you spend for every mile you drive!

    ex: My truck averages 14mpg. Price per gallon here currently is 3.39.

    3.39/14= .24

    So I spend roughly $.25 for every mile driven. Helps to plan for road trips

    Last fillup my 1998 Suburban got GREAT city mpg
    411 miles/26.5 gallon=15.5mpg
    I drive exactly 6.2 miles one way to work the last 3 months-city but not too many stops
    most importantly my wife hasn't been killing my mpg with her 1-2 mile trips and long waits-motor on-at the bank etc.
    I motor on pulse and glide-but that is about it for mpg trickery.
    GM 1/2 tons have transmissions that glide in D as if they are in N when you lift off the gas-makes them great for mild hypermiling.
    Once I get in better financial shape I might upgrade to a 2004 5.3-to get better brakes and better mpg-and fewer miles-222,000 now.
    Yeah GM trucks can get pretty surprising city and hy mpg
