Now this is getting down to self-doubt territory, wondering why am I driving a V8 truck around town? I used to get closer to 15. I could live with that but 13 and heading south?

 

sounds about reg to me

 

I average 13-16 in my 2011 with mixed driving. Typically, I do something like 80% city and 20% highway. I don't think there's anything wrong.

 

Sounds about where I'm at. I average 13.8 with 70% highway and 30% city.

 

So many factors influence mileage. You will get tons of answers on what others are getting. Remember also that now we have that crappy "winter blend" gasoline that always makes mileage go down, mine always went down in the winter. Make sure your tuned up, tires are at the correct inflation, etc. and wait it out till spring....

 

I get anywhere from 13 to 16 in the winter. Summer I'd regularly get 15-17. That is 75% city and 25% highway.

 

hahaah i got 11.5 last tank of 75% highway and 25% city, but i got the hypertech tuner, and will be playing it this weekend.

 

Right now I am 100%town driving but there are some nice open stretches. I suspect ethanol too. The idiots are making us actually burn more gas in the name of saving gas. that extra 2 mpg translates to 30 miles a tank. Although even compacts that people thought will be getting 40mpg are shocked to find out 25mpg or even less is all they are gonna get. So we are at worst 10mpg down from econoboxes.

 

I got 11.6 my last tank and the tank before that was 9.4 and that is about 90% city, but I'm using remote start all the time and 4x4 pretty much all the time.

 

I was getting higher mileage in my 5.9 R/T. The V8 I have now is a shadow of that 5.9. I don't think I have ever been able to spin the tires.
