    What are you guys getting for mileage with 2500HD 6.0 gas motor? Think I'm going to close the deal on one tomorrow.

    my 2003 2500hd with the 6.0 and 4.10's got between 10-12 mpg all the time, wether it was highway or city. crappy, but consistent. it actually did better with the 285's on it i think.

    Not the greatest, but not too bad either. My Duramax gets a little better than my 6.0, not by much though:rolleyes:

    I average 11.6 around town. Get about 13.2 on the highway. Pulled a 24ft enclosed car trailer from Chicago to Las Vegas and got 7.3 mpg a $4.39 a gallon...ouch

    I get 9 to 10 mpg every tank with my 8.1. I allways thought that was good for a 496. Allways figured the 6.0 should get a little better than what they seem to get. JMO

    I can get about 13 city and have gotten 18 on the highway, as long as I kept it under 70. Mine has the 4:10's in it as well. But helping it breathe a little better helped for sure!!!

    I am afraid to check it, one of these days i will do the math, i just see the needle drop. It was doing pretty good until the gas prices went down, now it seems to be sucking more gas.:dizzy:

    I just figured it up....roughly 10-12 in town and 15-16 on the highway. My Duramax gets 13 in town and 16-17 on the highway.

    I'm getting a little over 12 mpg on my 98 7.4L when running empty. This is after changing the two pre-cat O2 sensors. I was getting 9-10 mpg before running empty. I haven't towed or hauled anything since changing the O2 sensors so I don't know what the mileage is yet. Before I still got around 9 mpg towing.

    Biggest difference between the Duramax and the 6.0 is when you are towing. Then they are night and day.

    Don't buy a truck for it's MPG. Buy it for getting the job done. Duramax is the only game in town for long-haul heavy towing, but a great way to waste a wad of cash for putzing around town with moderate loads and/or snowplowing. The money you save buying a 6.0 vs a diesel will buy a LOT of extra fuel. I bought the D-Max purely on puny penile syndrome and the fact that I can afford it regardless of practicality. I would have been better off with the gas burner for what I use it for if I had to answer to the bottom line for justification.

    there's blackbearperformance also, they do custom tuning. They send a scan cable out. You put some software on a laptop and they do the tune specific to your vehicle. They also do standard mail order tunes as well.
