Guidelines to follow when using the gas cost calculator

When entering numbers, do not use a slash: "/" or "\"

Daily mileage
: It is the number of miles you drive your car daily. Just enter an estimate.

Cost per gallon: It is what you pay at the gas pump to put gas in your car.

Gas tank size: How many gallons of gas can your tank hold when it is full?

Days between fillups: How often do you fill your tank? Is it every 2 days, 3 days, 4 days.....? I fill mine every 6 days.

Take a look at the figure below to see an example of how to enter number.
