My brother just got an 05 150 ext. cab short bed and wanted to know what u guys are getting in gas mileage?? i have the 5.4 with 3.73 and im only getting 12 mpg, whats up?

 

My '08 F-150 Scab with the limited slip and 5.4 engine gets about 15 mpg with less than 2,000 miles on it. I only use Shell or Exxon, no gas with ethanol, and drive normally.

 

05 F150 Screw 5.4 liter - 20-21 on the highway

 

good fuel:
14ish MPG city
20-21 MPG highway

current crap fuel:
12.5 to 13 mpg non blown
13+ blown with hard launches and full throttle fun. can't keep off the gas to see what a tank would be easily driven
?? MPG highway...not any to test it out with

 

My 08 with the 5.4 and 3.73LS and get right at 13 in the city.

 

14.5~15mpg mixed driving to/from work empty in the back. I average closer to 14 when I'm hauling crap.

18 mpg tops on freeway averaging 70~75mph the entire 30gallon tank, empty in the back. I got about 17mpg on the same trip fully loaded with 4 people and the back full of crap.

My '05 FX4 screw is bone stock and I consider myself to be easy on the gas pedal. I only use Shell or Chevron gas.

36.5K on the truck now, and mileage has not gotten any better or worse the whole time, although mileage seems to have dropped <0.5mpg on the latest PCM flash earlier this year which made my shift points a little later and smoother.

I drive without my 90lb spare tire except on long out-of-town trips. That's less mass (and less gas needed) that has to be accelerated around all day. Does it dent mpg's? I doubt it's measurable, but the truck does feel a little lighter.

 

Who cares gas is under $2 a gallon and dropping fast.

 

Don't get used to it!

 

[troll] encourage all your neighbors and friends to take the bus, carpool, and buy/drive more Priuses and sub-micro-compacts. There'd be plenty o'cheap gas left for the rest of us gas hogs

Actually, it was nice when gas was $4.70+ around here. I could actually see over the horizon when I'm driving. Now the weekend SUV's are back out in force on weekdays.

 

16.4 average with my 08 screw 6.5 box,5.4,4x4,3.55 rear.have seen 17.2 on my huntin trip across ND and back but under my normal driving its really around 15-16 mpg...

 

I have an 07 5.4 4x4 with 3.73 gears, supercrew cab and 6.5 box

I have never calculated its in town mileage, rarely ever drive it in town, I take the car for that.

On the HWY if I am gentle it gets 18 MPG, driving a little quicker it gets 16 MPG....towing in hilly country I can get as bad as 8 MPG.

 

My '05 F150 4X4 w/5.4 gets 16mpg

 

14.5 city and 20-21 highway if I keep my speed down to 65. Drops to 18-19 at 70-75.

Towing my Jeep on a flatbed (6800 lbs towed weight) I get about 11 mpg at 65, and 9 mpg at 70.

 

so what do you think is up if all you guys are getting at least 3-4 mpg better? could it be because it sat for over a month at the dealership cuz he droves like grand pop when I'm in the truck but who knows what he does when hes alone. thought id ask since hes been bugging me.

 

Driving style, hills, and elevation can cause widely varying gas mileage. Someone who lives at sea level, never climbs hills, and does 99% highway driving at 60 mph could probably get 22-23 mpg. Someone who lives at 6000 ft and drives over 10,000 ftmountain passes every day at 80 mph will probably get 8 mpg...
