A couple of points to add here. Most members here are Americans. In Canada we use litres and used to use Imperial gallons measure. Now the Mericans use a US gallon coz they like to be different. A US gallon is smaller than an Imperial gallon. So if you use litres you have to get the conversion to US gallons right so you can compare apples to apples.

My previous car was a Miata and the local club prez used to say don't overfill the gas tank coz it could trigger something(CEL?). Anyway with the Box this does not seem to trigger anything except excess fuel on the ground. However if I fuel to the first click of the pump then it probably is about 7/8 full. If I keep on pumping even though the clicks continue then I can get several more $$ of gas into it. So now I don't fill it up completely coz I don't check the gas mileage as often. It is too depressing to do so. As my daughter used to say you don't buy a Porsche to save gas! Anyway for each Imp. gallon I get 20 around the city and 30 on the hiway. US gallon a bit less.
Of course the right foot has a big impact on mpg.
