she's just about finished and making me very proud.

 

1991 F150 351 5.8L
Stock 15 x 7.5 tires
E40D
Not sure what rear end it is, but most likely whatever it rolled outta the factory with.

Right now I'm averaging 10mpg, but I mostly attribute that to it being winter & letting my truck warm up sufficiently before driving. Also because my job duties right now have me driving back and forth between work and another location on a daily basis, so there's a lot more starting and stopping.

My average over the last 3 years has been 13-14 depending on how much city driving I do.

Massive "Deer Slayer" pipe bumper on the front, weighs about 250lbs w/ winch mount, lund visor.

93 F-150 4x4 w/ 5.8L.

I towed a u-haul 5x8 trailer last night about 100 miles, and it took me 3/4 tank of gas. Before i filled up again, i had 100.3 miles on the trip meter and it took 11.889 gallons to fill up, which by my math means I was getting about 9mpg...which seems really bad....

 

95 F 150 XL 2WD 5.0L 4R70W Dual Tanks 4.56 gears 6 inch lift

I Usually put 91 octane in if the wallet allows

with 235's about 14-15 MPG

with 33's about 11-12 MPG

 

1996 f250 5.8 2.25 true dual exhaust, straight pipes with glass packs , K&N replacement air filter 235/85 12-14mpg

 

1987 F250, super cab/long bed 2wd, 6.9 idi, ZF S5, 3.55 LS Sterling 10.25 rear. Stock as a rock, and I get 16-18, depending on how fast I try and go up hills.

 

You know you are just wasting your money putting anything over 88 octane in right? Unless you have the timeing advanced far enough that you need the higher octane rating, I wouldn't worry about running premium.

 

What should a 95 f350 460 5spd 4.10 2wd stock height/tires get?

 

i have an 88 f350 4x4 crewcab, longbed with 460ci and from what ive been told 4.10 gears. running 35x12.5/17 tires. at 55mph im at around 2800-2900 RPM. im getting between 9-11 MPG. im sure if i would be able to lower my RPM a little, my MPG would be a little better. i dont hotrod it around thou, those days are over. gas to expensive. any ideas on how to lower my RPM's without having to spend lots of money would be appreciated.
i have a C6 w/ no over drive and i run regular gas in it. 88 octane.

 

Specs are in the sig. I get 8.5-10 city in the morning and the truck never even warms up, so I'm sure that's not good for mileage. As for highway, 14 with the cruise @ 80mph to keep with traffic. Next trip up north I make will be with cruise @65-70mph, with all new vacuum system and fuel injectors. Hoping for some increase. Will report with results.

 

My 1988 F-350 4x4, 1973 468c.i., C6, 4.56 gears, 37's

9.5-10MPG Highway, city, uphill, downhill, with or against the wind







The little Ford gets 25-28 MPG highway cruise depending on speed, and 20-22MPG city. 1968 Falcon Futura, 200c.i I6, 3 speed auto, 2.50 rear end

 

93 F150 in sig- 17mpg cruising at 60mph (3.55 gears and E4OD), giving it hell in town.
87 F250 in sig- 22mpg +/- 10% cruising at 1800rpm(3.55) drove pretty easy.

 

1988 F250 dually, 460, C4. I wanted to scrape the factory exhaust and convert it to cat free duals. My muffler guy said it would perform poorly since it has a front and rear O2 sensor and heat tubes. His fix was to increase the size of the exhaust rear of the cat to 3" and then 3" inlet to the muffler and tail pipe. I got 9 miles wherever I drove conservatively. Took a ride to upstate NY from PA and kept a steady 65-70mph on the long roads. Now 12mpg and it cost me $350.00.
