Tank capacity is irrelevant. Do this:
Fill the tank 'til it clicks off. Reset the trip odometer. Drive.
When you fill the tank again, write down the gallons consumed since your last fill-up. Divide the number of miles you've driven by the gallons used to determine your fuel mileage.
This is the only way to accurately calculate fuel economy.
