    Also, another thing to consider is what gears you are runnin? Mine has 4.10's and honestly for what I use the truck for, and with the granny low in the 6 speed, I've conddred dropping to a 3.73 or 3.55. I have so over the road hauled friends that run a taller gear strictly for the milage. They say with the granny low, the 4.10's are pointless. I know im revving at around 2200 rpm's down the highway at 70.
    zuk buggy.....it'll be a jeep eventually.

When I bought the truck I took it to a shop and they said the injectors were fine. that was 10,000 miles ago. I was told if they were bad it would smoke at a idle. Mine dont smoke when idling and only slight smoke at full throttle. I have heard that 13.5 was normal for my truck and some people say they get 20+. Id be happy with 19-20 mpg.
      Stock tires are 265 75r16s, checked your air filter recently? sounds dumb but give it a check also i really can recomend a 4" back exhaust system.
      mine is 4x4 auto getting ready to be lowered 2" all around with 285 60r18 nitto terra grapplers.

          I've got a late '99 2wd F250supercab. It gets 15mpg pulling a 9000 lb. trailer/truck combo. Don't know what it gets by itself, only use it to pull. I've thought about getting a TS chip, but lots of other stuff to spend $ on before that.

              All of you are doing better than my 08 F350 dulley. Ran from Cleveland to Hamilton yesterday pulling a 12 ft. box that was empty. I got 11.2 mpg running 65 mph. Pulled my 20' box last weekend with my Wrangler in it. I got 9.7 mpg at 200 miles round trip. At 4.00 a gallon this thing is killing me!!!!:mad:

                I've got a 06 with a 6.0 (yeah, I know) and a SCT tuner on the performance setting. Around town, I get around 16, on the highway, I can get around 19 if I set the cruise and not get in a hurry. On the 65 hp tow setting, I get around 13 or 14 depending on terrain. That's hauling a deckover with a Jeep on it.

                  I use an '02 van with a 5.7, a quad in the van, pulling my 28' toy hauler full with a tracker and 2 quads only get like 6-7mpg I think it needs a tuneup and that's horrible mileage, but I guess if I'm only gonna be getting 12-14mpg anyays with a diesel then I guess I should just be happy i'm not making payments on one

                    You can improve on that, but I would wait until you get closer to the end of your warranty.

                        I thought you sold your truck, I saw what I thought was yours on a Dealer Ad in your area.
                        I've got the same truck, do you still have the original heads, gaskets , studs etc.? I get ~ 14-15 unloaded and 10-12 towing 7K.

                          I had it for sale and a kid told me he'd take it then backed out. Since then, I bought another crawler and trailer, so it's sticking around for a while. It's completely stock with the original heads, studs, gaskets, etc. I talked to the guys at SCT before I bought the tuner and was told that it would be safe as long as I stayed out of it. I have a pyro gauge and it never goes above 1200. I'm sure it won't last forever, but I treat it pretty nicely.

                              Wow it's amazing what an air filter and fuel filter do.I can tell it's not sluggish and it's got more gitty up.
