    Talking Brand New

    I just got my new 2500HD CC LT3 4x4 day before yesterday (09/26/06). I had to drive to a new contract site, about 300 or so miles, and got 16.49 MPG hand calculated. That is a great improvement over my 2003 Silverado SS that got 12 - 13 with the 6.0 HO. This new truck is great!

    I just got back home after a 500 mile trip, not towing and with the a/c off. I manged to keep it at 65mph the entire trip and 99% of this trip was on limited access highways with the cruise on. I have a '06 CC LBZ and it turned over 6,000 miles this trip. Overall economy 22 mpg. I have made this trip before with the a/c on and it drops to 20 mpg. I'm happy. Ed

    Default First Tank!

    Got the LBZ full up from the dealer. Just filled up for the first time. 16.66mpg. Diesel is now cheaper than even regular gas around here. First time I filled a tank over $75.00 worth. the system just stopped right at $75. I had to reinsert my card and do another coupla gallons! Anyway, for a first tank and mostly city driving I thought that was okay mileage.

    That's actually pretty damn good considering that it's fresh off the lot and hasn't had a chance to break in yet. Mine didn't get consistent 16 (city)/18 (combined) until i hit nearly 5k miles and had already changed the Oil.

    Diesel is slightly cheaper than 87 RUG here in Los Angeles right now, but about 3 months ago, Gas was near $2.0X and i was still paying $2.55

    As i drove past a bunch of stations today, Cheapest 87RUG - 2.98 (ARCO aka Cheap-Gas) And Diesel from my favorite station was a modest 2.77 (up from 2.68 Last Week)

    The Gas vs Diesel price is sort of a wash, as one can't really predict why all of a sudden prices shoot the way they do.



    Notes:
    • This is not the most conclusive (as far as fuel prices go, i may not have shopped around the best).
    • There are several fill-ups missing, most notably in the beginning and some in the middle, due to lost receipts :-P
    • Note the best tank avg of 18+ mpg (made it back from Vegas on 1/2 tank, getting 22mpg @ 67mph, then kinda wasted the 2nd half of the tank.



    I still like my Diesel though. Don't think i'll go back to a Gasser anytime soon, not in a truck anyways.

    I have installed the Edge Evolution and have the #3 tune installed. Using the DIC alot, but it seems very close to actual when I compare.

    I used to get 16-18 with mixed driving, now I am getting over 20 with mixed driving

    I do hear a little more rattle, but not much and for this MPG I can live with it.

    Cool Does it really matter

    Roughly 18 - 20 MPG if I don't put my foot in it, but what the sense, if you can't show off.

    Default 15.7mph

    I have a 2500 HD Crew cab 4 inch lift LBZ I used to get about 9.9 towing(8400lbs Fifth wheel) and about 14.3 not towing on the Highway. I put on a Banks Monster exhaust, and Banks cold air intake, and I used a Superchip programmer. Can you say Rocket. I towed a Aluminum car trailer and a Chevy Caviler 400 miles with the new upgrades with 4100 pounds and 15.7 mpg I could not be happier. (55-65) Climbed the Grapevine in California twice during this trip. I was very reluctant to do anything to my baby. But it seems this was the right choice. Goes very fast if you let it, or make it. I look forward to visiting the pumps again. 500 Hp up from 360hp stock, 740ft lbs torque up from 650, according to the very happy parts man who sold me all this shiney stuff for $1800.00 . I figure I am saving 10.00 per 100 miles driven just while towing mind you and you gotta love that. Now if I can just keep from showing off at every stop light I will be doing very well.

    Smile Lovin my 07 Crew Cab long box

    I just filled the tank for the first time and I got 17.2 Mpg and that was a combination of City and Highway miles. It includes a 50 minute sit and inch along stretch due to an accident. I am quite pleased. Towing a 8000 lb trailer this week so I will let you know the mileage after this trip.

    I get 20 mpg at 65 mph not towing on average all highway. This past weekend I towed a 9,000 boat (total weight including trailer) with a T-Top 225 miles all highway at 60-65 mph and it got 12 mpg. Not too bad I think. Comments? Ed

    Default Increasing MPG

    Running unloaded on the highway - meaning not towing anything - I got a high of 19.7 mpg in my '07 LBZ CC SWB 4WD, running 70-75 mph. I think that's the highest mpg I've ever gotten from a 4WD pickup, gas or diesel ('01 LB7).

    Hey all.. I have a 06 GMC short bed with a little over 20000 miles on it. Last summer and early fall I was getting just shy of 23 MPG on the highway. Running between 70-75 mph. I went up from the factory size tires. From 245-16 to 265-16. I didn't pay that much attintion to the milage after that. Then in October I went on a trip. From WV to WY on a hunt and visit. My milage on the highway was 16.3 at best. Now, running around town and such is 12.5 at best. What in the world happened to my milage.
    The service guy at the shop told me it was because I changed the size on the tires. I just can't believe that 1 size would cut my milage that much.. Any help would be appriciated.

    Did you adjust the speedometer to compensate for the tire change?

    23 mpg at 75 mph sounds a little fishy to me. Are you sure? Was that by the DIC or calculated?
