Fuel Mileage

[Loneranger]

I have been getting in the 15's combined town and highway. Pulling about 6k pounds up the mountains I got 12.6mpg, these numbers im satisfied with but yesterday I took a highway trip, set the cruise to about 64mph so I was just below 2 grand. After I got back, I fueled up and checked my fuel mileage, got 16.X mpg. I think I should be getting better than 16mpg hwy dont ya think? My buddy gets 20mpg all the time in his 97. I have 285 Goodyear MTR's but the tires shouldn't make that much difference should they? I dont know. What do you all think? That was also my first tank adding SCW-III 2 stroke oil. I added it at 1oz per gallon. If anything that should help the fuel mileage, not hurt it right?


Thanks

i have a 2000 f250 with a 6 spd and i am averaging around 14 mpg with no chip, but i am running 37in mud terrains. the best i have ever gotten was 21mpg cruising down the freeway with no trailer.

and about the 2 stroke oil.....i have heard of people doing that and was wondering does it help? what exactly does that do?

In my truck now running the TW in tow/ eco/ or extreme i can run around 16-17 mixed driving. Hwy maybe 18 or so. If your towing i wouldnt even worry about mpg. But without the TW i was running about 12-13 mixed so i gainede a good bit.

Old truck was a 2000 7.3 2wd 6sp. Got 21-23mpg stock, and all that is hand calculated. On my overhead now it says 26mpg

That sounds a little low... My last tank was mostly highway driving (72 MPH) with a bit of towing my boat (3000lbs) and a trip to the lake (hills), and I averaged just under 17 MPG. Don't forget to correct for your larger tires. Also, are you filling the truck ALL the way up to where you can see diesel in the neck (not just foam)?

16mpg at 1900 rpm? and thats 64mph???

haha

with no load, i can keep a steady 2000rpm at 70mph and get about 24mpg going to the beach and back

btw 6 speed

Sounds like he has 4.10 gears.........like me. I get 15mpg with stock tires and keeping it at 70mph. If I can restrain myself and keep it at 2K, I get 16. E-99, 4x4 dually, auto, Banks intercooler/wastegate and 6 Gun on power level 6. I just installed the Ford AIS and will check this tank. Want to go with a 4" dp and exhaust, too.

I don't know if my truck sucks or you guys are drinking too much beer while punching in numbers on your keyboard...)

Mine is year 2000, 2WD, 3.73, all stock, 125K miles on the clock. The best on freeway I ever got was 16 mpg at 65mph. Towing a 7,000 lbs camper on flat terrain I got 11 mpg.

I'd be hog in heaven to get 18 mpg on freeway.

I get 14mpg in heavy city driving (lots of stop and go because our stoplights are stupid) and 19mpg highway.

I also get 14mpg towing on the highway.

I have an 05 CC 4x4 and get 11 pulling a 6500 lb 5th wheel to the Smokey's and back. Got 14.9 solo (best tank on the HWY). Dont know the gear ratio only owned the truck 1.5 months.

Get stage 1 single shot inj and youll pick up 2-3 mpg
