I took a trip from Baltimore to Charlotte NC over the weekend. A lot of big hills and mountains on the way down. I reset the mileage meter and averaged between 19.5 and 21 mpg. This is with an average speed of 70-75mph, air on, occasional cruise,3 people in the car with luggage in the back. Im pretty happy with that. I get about 14.5 to 15.2 around town if im not ******* it.

I noticed that the truck has a little drone at 75mph with the factory muffler.

 

Thats good...I could get that if I wasnt always getting on it buuuuuut its so hard not to, these trucks have SO much power!

 

My problem too can't seem to keep from WOT

 

I drove from Houston to Dallas and back avg. 75 mph. It's a pretty flat drive and cruise control was used whenever possible. Starting from a full tank to gassing up on the way back I calculated 16.8 mpg based on fuel added divided by miles driven on that tank. The evicted showed over 18 mpg. About 99% interstate driving. 16.8 is crappy to me but I can live with it. I avg. About 12-14 in the city depending on mood and shoe weight. I have 3.55. Wish I had 3.92. Anybody want to trade?

 

I don't want to trade-just bought mine in April--a 2010 1500 TRX with hemi and 3:92 4by4--I have only about 1100 miles on it--but getting about 18 when most of it is on open highway and and about 11 to 12 in town with all the "red" lights. (I never call them "green" lights as they are almost always red when I approach--lol). This is somewhat with babying it. Usually if I am first in line when the light changes I am sitting at the next light before anybody else gets through the previous light. Yeah, I know, I need to grow up --what the heck--only 67--maybe I will yet. LOL
I figure when I open it up in town I will be getting about 9 or so mpg. No use buying a hemi and letting a little Civic beat me off the light--LOL.
