01 50k miles, see sig. torque tubes on it now. I answered 15mpg, which is what I get if I baby it at 60-65mph. My friend borrowed it for a weekend and put about 1000 miles on it, and got 16. He was pretty nervous and was probably very cautious.
1999 super cab 4x4 shortbed with 4" lift & 35" tires. I normally calculate about 10-11 mpg on the highway so I voted 12 mpg to account for the bigger tires making the odometer reading off by a few miles.
Ever since I got my '99 F250 CC SB 4X4 in April I have had rare opportunity to measure highway mileage since I've either been towing the camper or piddling back and forth two miles to work and back. Last week I took her on an empty road trip (2 lane road 55mph speed limit, cruise set at 63mph, 100 degrees F, A/C running on MAX) and calculated my mileage at 13.7 MPG. My '96 Tahoe I had previously would only get 14.5 on its best day. I was very happy with the mileage. It's bone stock with LT265/75/R16 tires, toneau cover, and 143,000 miles.
My on board dash computer says I get 18.3 MPG running on the hwy for 100+ mile drives, all on cruise going 75 to 80. Use a SCT Xcal 2 w/ Street or Performance tune w/ ERG off, 4" turbo back exh, Airaid cold air intake, & Accufab Intake tube.
It shows 15.2 in city driving.
Hand cal shows something less but that includes startup, idleing, city & hyw, all together.
