well its a carb'd motor as opposed to EFI (which is more efficient).. plus like others have said u got an auto tranny, which most of the time aint as efficient as a manual tranny. regardless, even tho ur motor is carb'd it should still get better MPGs than that lousy 14mpg u mentioned earlier. check ur fuel, air filters, and tire pressure. also take a look at the carb cuz it could be improperly tuned which may cause it to run rich, hence poor fuel economy.
