Both the MT2 and the Magnum are comparable in gasoline consumption, about 10 to 15 minutes run's for each. Also, it depends mostly on the way you drive, how fast and the amount of heavy throttling that you do. But if you consider the basic facts that the NX 3.0 is a bit larger engine than the .16 of the MT2, then you could probably say that the NX 3.0 engine does consume fuel at a faster rate.
