Hello I am wondering what is the best fuel mileage anyone has got out of the 460. How did you achieve it and how much money.
Thanks Logan


Currently own 1991 F-350 4X4 XLT Lariat Crew cab 7.5L ,Std

1997 F-350 4x4 XLT Lariat Crew cab 7.5L, Automatic

 

11mpg by driving it at 60mph unloaded.

 

thru the winter 12 to 13.5 with cap on and 300lbs in bed ( 2wd )
in the summer no cap empty managed 15.2 on a 500 mile highway trip
towing a 9000lb 5th wheel it drops to 9mpg
cut out intake horns , headman headers , no cat , 3inch exhaust,
6 litre tune up , k and n panel filter , need to do a maf conversion to see if i can manage any more empty

Has anyone tried using super chips or anything in that sort of field to acquire better fuel economy? I also found a site they claim their exhaust system will gain 10 to 15% better fuel economy with 68 more hp and 100 or so torque. Could this be true?
Thanks Logan

 

No it is not.

 

zxwut is right.

I am looking at buying a 1997 460 crew 4x4 right now, and I was floating some ideas about improving mileage as well. The best I can think of are: Full performance exhaust system, performance ignition, a moderate rear gear, and a light foot.

 

Truck in sig w/ 3.55 gears: I've managed 14.2 and 14.5 both on 250 mile trips, on a state highway with practically no stops and a constant 55-60 mph. Truck was unloaded and I was following other traffic; not drafting really (don't want rock chips in the hood), but I wasn't the splitting 100% of the air myself either.

 

I've got 4.10's, so you have a little advantage there

 

I found this:
FOUR WHEELER Magazine's Project M.P.G.

 

11.6 is the best I've ever gotten. Steady 65mph in 5th. I've got stock gears, 37x12.5x17 tires.

 

13.5 over 1350 km road trip, empty, cruise control @ 130KM/hr. 4x4. ext cab LB, k&n drop-in, no cats, no intake "horns".

 

imho,you asked the wrong question.
you should have asked who has the BEST AVERAGE MPG,if you wanted to see real world numbers that mean anything.
also asking for the amount of tanks back to back were included in each persons results could help you find how accurate each were,and which to toss to the side.
just a suggestion for next time.

 

My 460 seems to get better milage loaded on the highway. My work site is approximately 25 miles from home and it drinks a half a tank a day. But, a short while ago I went to another town about 20 miles further down the road to pick up a free slide in camper I found on CraigsList and round trip it only used a quarter tank. ?? AnD it was extremly windy (cross winds) the day I picked up the camper. What gives?

3 year old thread but I'll play, 14 is my best. Empty on highway, 5th gear at 55.
