This obviously will depend on the mileage per gallon that the engine will consume. Take cars for example. A Bugatti Veyron at full speed covers 3.5 miles per gallon what would give you an autonomy of about 63 miles with an 18 gallon tank. Smart (Mercedes micro car) with Diesel engine makes 48 mpg what would give 864 miles with the 18 ga tank.
