The fuel tank holds a nominal 13 (UK gallons) of fuel which is about 60 litres.
I have managed to get 14 (UK gallons) or about 65 litres in mine but this up to the top of the filler neck and not recommended for safety etc.
The reserve light seems to come on with about 7 litres of fuel left in the tank.

I get anywhere from 23 mpg (Town) to 34 mpg (Highway) crusing at 65 mph or below.
At 75 mph and above don't expect to get much more than 25 mpg.
Towing a loaded trailer (1000 kg) you will get anywhere from 18 mpg to 22 mpg.
