i have the chance to get a 1989 f350 its a 4x4, auto tranny, im not sure what rearend gear is in it though. my question is what kind of mileage do you guys get out of yours.

 

I picked up a 91 2wd sc dually just before gas went from expensive to ridiculous - got 12 to 13 with my first tank - it's bone stock, and needs a tuneup methinks

 

My 93 F250 with Dana 60 up front, 3.55 gears,ZF 5speed,35 inch tires, I can get 15mpg on the highway easy. But mix driving I get about 12mpg's. At 55mph I am only turning 1500 RPM, Foot is just resting on the throttle. Winter rolls around soon and mileage suffers alot. Last winter I only averaged about 10-11mpg, Mornings were cold -25 degrees below. I only have a 11 mile trip to work so the engine doesnt get up to temp for the first 6 miles or so. I dont let it warm up at all.

 

87 460 4bbl F250 4x4 33" x 12.5" BFG AT tires 4.10 gears ZF 5 speed 240,000 miles

I got 10MPG around town & 11 MPG highway

I'm rebuilding the motor with a mild (bigger than stock) cam, headers, and Performer intake. I'm hoping to pick up 1 or 2 MPG. We will see.

Also, removing the tailgate has added about 1 MPG to what I listed above (highway). 1 MPG may not sound like much, but on a 10 MPG truck, that's 10%!

 

I was getting 8-10 before the mods, with 33" tires, 3.54 gears and an auto tranny. Now I'm at 4mpg but that's what happens when you pump up the engine, have 200 pounds spinning per corner and drive like an idiot.

 

This is scary, an HONEST man.

 

You go Ivan !!!

 

I have a 97 f250/w 460 and 4.10 gears 4X4. When I first bought it I got about
6mpg towing a 27FT TT. I have added headers,3" exhaust,straight thru muffler,
hot coil,MSD ignition and 8.5 plug wires Have modified the air intake system, I now
get on average 9MPG towing the trailer. The MSD 6A ignition module gained me about
1 MPG. Plan on completely revamping the air intake system by removing the stock
Ford ducting and installing more direct ducting. I noticed when I took a trial run without the ducts connected to the intake manifold, Had noticeable increase in power.

 

91 F250 4x4 with 460 and 33 inch tires, best Higway mileage was 8.8 mpg and when playing around and spinning tires I get 5.
My 79 F150 2 wheel drive with 460 averaged 16 all the time. I really miss that truck.

 

87 F-250HD 460, 4x4, 4.10's, C6, bone stock, towing i get 9, highway i get 9 city i get 9, foot in it foot out, I GET 9. my truck scares and confooses me WAAAAAAAY too much. I suspect a tuneup would help, but, well, i cant come up with a good excuse at the moment, but i'll figure one out sometime.

 

1995 F-350 Reg Cab 4x4 5spd 4.10 33" Mud Terrain

8.8-9.50 mpg (Town + Bass Boat)

9.50-11.0 mpg (Town - Empty)

14.0-15.50 mpg (Bass Boat @ 65 mph)

16.0-17.0 mpg (Empty @ 70 mph)

Thats with a real light foot.

 

Not to be a Jack@$$, but if you want good milage buy a hybrid, if you want a truck with gobs of horsepower by the 460... lol

 

Will you garuntee that hybred will tow my 12000 lb or more trailer....lol

 

Nope, I'll guarantee it won't... but if you're towing a 12,000+ lb trailer I wouldn't be worried about good mileage because you aren't going to get any... I'd be more concerned with good brakes... lol

 

My mileage is right where Gene K is. What never ceases to amaze me about these trucks is our ability to crawl up the side of a mountain at .5 m.p.h., carry insane loads in the back of them, fly down the highway at 70+ (sometimes WAY plus), and do it day in and day out without many issues. My truck is at 310,000 K (I think thats somewhere around 200,000 U.S.). Yep, I wish I had better fuel economy, but it pulls anything I hook on to, is a daily driver, has been up and down various mountains hauling stone, logs, etc., and is frequently called upon to make a quick run on the highway out to my cabin. Other than the expected cost of oil changes, tires, and brakes, my only unexpected expense was a broken clutch linkage last winter- a $100.00 new parts fix. There is no better feeling than that of a truck that will start when you need it and will do as you ask of it (within reason). I'm often tempted to go out and buy a new one, but there are just enough horror stories of newer trucks out there that prompt me to take mine out and give it a fill-up, an oil change, and a drive into the car wash.
