Stick the tank like real truck drivers do.
next time you are almost empty, mark a stick. put 10 gallons in, mark the stick again. add 10 more gallons, mark again... continue till its full.
Then add up the amount it took to fill, sub tract that from the tank capacity and you will know what you started with. right that number on your lowest mark.
you will always be sure and the stick will never lie to ya.
