The standard 2014 Dodge Ram 1500 travels up to 650 miles on a full tank of fuel. This is based on gas mileage of 25 miles per gallon during highway driving on a full 26-gallon tank.
While most 1500s are equipped with 26-gallon tanks, some Longhorn and Tradesman models are equipped with 32-gallon tanks, according to specification charts posted on AOL Auto. This potentially boosts a single tank's output to 800 miles. Additionally, models like the SSV 4x4 Crew Cab and some of the Tradesman Crew Cabs have fuel efficiency of as little as 13 city miles and 19 highway miles per gallon, resulting in performance ranging from 338 to 494 miles per tank.
