saw this on another forum thought i would share All MPG figures assume an empty truck, driven at the posted limit. One-third city/suburban, one-third, two-lane state roads, one-third Interstate driving. Flat terrain. Year round averages. Base configuration 7.3, 6.0, 6.4, or 6.7 engine or any Cummins engine in a Ford truck ZF6-650 transmission Super Cab Single Rear Wheel 3.73 gears OEM Rubber Open bed, tailgate up 18 MPG MPG Modifiers 4x4: Subtract 2.0 MPG Automatic: Subtract 1.0 MPG Regular Cab: Add 1.0 MPG Crew Cab: Subtract 1.0 MPG Big Tires (bigger than 31.7” OD): Subtract 1.0 MPG Lift: (3” or greater): Subtract 1.0 MPG Dual rear wheels: Subtract 1.5 MPG Open bed, tailgate down: Subtract 1.0 MPG Flush top cap: subtract 1.0 MPG T onneau cover (full length, soft or hard): Add 1.5 MPG (over open bed) Aerolid: (very rare): Add 3.0 MPG (over open bed) 3.55 gears: Add 1.5 MPG 3.08 gears (no longer available): Add 2.5 MPG 4” front/6” rear slam (not available for 4x4): 1.0 MPG 203 degree stat (7.3 only): Add 0.5 MPG So, if you have a Ford diesel, SC, SRW,4x4, automatic, big meats, and a 4” lift you should expect (18.0-2.0-1.0-1.0-1.0) = 13.0 MPG Margin of error: Plus or minus 2.0 MPG Sent from my Transformer TF101 using Tapatalk 2
using this id get 12 but i get more than that, ive even noticed a difference since getting my computer reprogramed for my tires Sent from my Transformer TF101 using Tapatalk 2
I've heard the 7.3 Powerstroke has a highway cruise "sweet spot" @ 2100 RPM, supposed to get the best fuel mileage at that RPM. This generally equals 72mph on my F250, my speedo is 1-2 mph lower than the GPS reading. I usually get +/- 22mpg pulling either empty or mildly loaded 16ft trailer.
I honestly dont drive mine enough to get an accurate mpg especially in the winter having it warm up forever and most my driving is errands around town Sent from my Transformer TF101 using Tapatalk 2
Shoot....+/- 2mpg I can do with driving habits I find that winter time kills my mpg more than anything. I go from 15 to 12....
