My mother drives a dodge 1500 with the hemi in it,I honestly don't remember the year maby 15-17. with the cylinder shut down tech, she gets as good or better milage than my ranger on the highway. However in town with the way she drives, I swear you can watch the guage drop. And I hate to say this but the engine and trans have been real good to her d.d. duty hauls a boat, she's been to Maine to visit my sister with it. But it was at the dealer several times for electrical issues, but the repairs have held and nothing since.
