    I haven't been here for a while so I better get caught up! I just checked mine on an empty road trip last week and it was right at 18 mpg.
    '93 crew cab dually 5speed un-touched with 150k on the clock. I did order some guages today as I had better pay a little closer with those miles....a little tune up is way over due. Thanks to all who have helped me out in the past , JEFF
    I miss this place when I have been gone a while!

    GMC; It's true but also driving habits, truck size, 4x4 vs 4x2, tire size, tire inflation, & maintaince all effect your MPG. I'm open to idea's we can set up to 10 questions on a poll. How would a gearing & MPG poll be set up? Any ideas?

    We'll you hit many, but let's see:

    1. SB Reg Cab truck, SB X cab truck, LB Reg CaB truck, LB X Cab Truck, Suburban, Tahoe, other
    2. 1500 4x2, 1500 4x4, 2500 4x2, 2500 4x4, 3500 4x2, 3500 4x4, 3500 duals 4x2, 3500 duals 4x4(do all 3500's have duals? if so, delete that portion of the question)
    3. Fuel Additive no or then selections which basically find out how many oz additive per gal of diesel (1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5
    )
    4. Condition of vehicle: Excellent, Very Good, Good, Fair, Poor
    5. Driving habits: Conservative, moderate, Lead foot (and add city/highway to each one of these)
    6. Thermostat 160, 180, 190, 195, 200, 205, 210, 215, none
    7. Overall rear gearing (rear end gear calculated with tire size to give an effective rear gear) (Gear Vendor guys must calculate this into account to compensate for the gear they are usually in)
    8. Stock Air Filter/Replacement upgrade air filter/Cone Air filter
    9. Intercooler Large/Intercooler Small/None
    10. Mechanical Boost control boost Level 6,8,10,11,12,13,14,15,16,17,18/ ECM Boost Control
    11. Kennedy PCM (a option for each level he has), Heath PCM 1.0, 2.0, Westers (and any others I may have forgotten)
    12. Exhaust stock/stock kitty removed/stock muffler removed/stock both removed/3.0", 3.5", 4.0", 5.0" (is anyone offering 5"?)

    You could probably get rid of question 4, asuming everyone's vehicle is average, or make an individual poll for excellent, very goog, good, fair, and poll (or just make 2 or 3)

    I know that still makes 11 left, but it's tough to get rid of any of those...

    How many options can each question have for an answer?

    GMC;
    You can only select one of upto ten questions? so you put the critria in and then you have MPG's. If you have 4 MPG scales for each 10 configuration that would be 40 selections very unwieldly. I think for those of us who have been around awhile we understand that a 4.10 dually K/3500 Crew Cab about 15-16 mpg on Highway is about average. Someone like me who has a C-2500 or C-1500 with 3.42's will get around 19-20 no problem.

    It can be, but if you represent it in a list format like a spreadsheet that has the vehicles listed in ascending order of MPG, and let the options be listed next to the mpg, It will show the trends in the data.

    I know it would be a daunting task, but if there is enough interest, I would be willing to collect the data and represent it in graphs, ect

    I voted 18 mpg, but there is a condition to get 18 mpg. I have to limit my speed to no faster than 65 mph. If I go over 65 mph my best is in the 16 - 17 range, and if I hit 75 mph it goes lowerrrrrrrr.

    I base my MPG # on repeatable numbers that I have obtained lots of times not a one time think that might have a foaming factor adding or subtracting from the actual MPG #.

    Basicly you have a question and up to ten responses. We have limited choices on the polls. I think to do what you want it would be better if you started a thread and we can stick it so it stays near the top. Ask for the data to be put in a certain order like 1. Vehical (C-2500, Sub-1500 ect.)
    2. gearing (3.42) 3. 2x4 or 4x4. ect. Then you could periodicly collect your data and make up a spread sheet. After a reasonalbe time frame for reasonses you could then post the findings.

    I was trying to make a straigh forward simple poll, I see the befit of collecting all the data you would like. I don't think we can do it with the standard Poll and it's limits.

    I have converted my figures to US gallons, it's pretty easy, even for me
    http://www.onlineconversion.com/fuel_consumption.htm

    My usual speed on highway is 62 MPH, or 100 KPH, which will reliably result in 20 MPG with occasional tanks as high as 22.5.

    All driving combined (city and highway) based on fuel and miles for an entire year in each of the first two years I have owned the old truck is 17.58.

    I thought about this Poll and reopened it as the DuraBux MPG Poll has been around and opened so that folks can add their results to improve the amount of info. This is a much more basic and quick Poll to respond too.
