It is more fuel efficient than it used to be but it still is more of a high performance than econimcal engine. If it is in a newer truck AND you keep your foot out of it, you can expect to get aroung 18 to 20 mpg. If you just can't help yourself and drop the hammer on it, your mpg will go down in exact proportion to the amount of fun you produce. Same holds true in a Challenger.
