    On my first calculation, I got 10.8 MPG. This is 75% city with auto transmission, 4.10 rear end. no towing.

    Does this sound about right?

    sounds about right! I have a 2011 and get 12 MPG (US Gallon). I say US as I am a Canuck! This is off my Iphone app. I can drive with a real soft right foot, keeping it under 2000rpms and do a lot better.
    The fuel mileage is directly related to my right foot.

    So we are in a cold snap weather is @ -12C and getting a bit worse mileage, Not huge difference but I have noticed it. About 0.5 mpg worse

    Wow that MPG scares me...... I am looking at a 2500 and I was debating on the 6.0L gas or the 6.6 Turbo Diesel....... if thats what people are getting in the 6.0L gas then I am going to avoid that all together when I make my 2500 purchase. ( I mean I know its not going to be a prius ) but 10-12 is really bad.:lol:

    I Can't disagree with you nakranj. But:neutral: !

    So to be totally upfront It was cold and it was all city driving. What I got a few weeks ago all highway driving with cruise set, 60-65mph and just wife and I was almost 17mpg. I'm not really upset with the mileage I'm getting, as I stated before, it is directly related to the right foot pressure.
    When I had my 09 with the 5.3 it seemed a bit more forgiving with the right foot. If one needs a 2500hd one needs it and your choices are Diesel or Gas. Yes I agree that it uses more than I want but the trade off for me is SAFELY pulling my 9000# Travel Trailer. I also use it back and forth to work about 15 miles a day.
    I just hope the juice doesn't hit 10$ a gallon!:lol:

    I here ya.

    When I bought the 1500, I could get premium for $0.89 per gallon... I could fill up 24-27 gallons for under $30. In comparison...... (percentage wise) My parents 1998 4cyl. toyota camrey cost them under $15 to fill up in 2000, now it is $45 ( shock to them ). I guess with a truck we expect to pay more. I think if it does go much higher than it is now, there will be a breaking point when allot of gas stations will fold cause no one will be going to them.

    I will work from home as much as possible..... unless I get a gas allowance/ or a large pay raise, you won't see me in the office much.
