Yes, yes...I know. Our trucks are not fuel efficient. Let's get that out of the way.

Last two fill-ups, by a genuine pocket calculator (actually, iPhone), show my city MPG as around 13.85. I've given up totally on the computer's "lies", which showed my last MPG as 16.9.

The last two tanks were 80 percent city, 20 percent highway.

I have a light foot (I'm 58 - been there, done that with the speeding, etc.). No mods to add weight, and have a tonneau cover (which I prayed would at least help a bit with fuel economy). No jack-rabbit starts, and try my best to keep it at or under 2,000 RPM.

So - is it me, or are those of you I've read claiming you get 17 to 18 MPG city that's fibbing?

Eh - no big deal, I suppose. I babied it this last tank, and truly believed I'd hit at least 15 this time, so I'm just sulking.

 

What engine, gearing? 4x4 or 4x2? I get about 17-18 MPG keeping it around 2,000 rpm. The computer is pretty close usually, within .5 mpg. I am about 50/50 city/highway, but "city" to me is winding country roads where I can cruise at 35-40 mph. However, highway is stop and go for the most part.

On long trips going about 65-75 I averaged about 20 mpg in higher elevations. Not towing anything but truck filled with gear.

 

Uh...yeah. Guess it would have been helpful to say it's the 4.6L 4X2 Super Cab.

Impressive that your computer's MPG reading is so accurate. I don't trust much about anything mine tells me.

My previously written issues about the fuel relay sensor are still unresolved. Hell, I can park on a slight downward slope with over a half-tank of fuel, and the next morning, I'm on "E" with "Zero Miles to Empty" showing.

I've just come to accept that issue, and tell my wife when it shows "E", that there's really a half-tank.

 

Is that the 2v or 3v? If you got the 4 speed trans this could be part of your problem.

FYI, my fuel usage: http://www.fuelly.com/driver/zski128/f150

I have not heard of that problem, but my driveway is level where I park so I probably will not have noticed this. I would think it should recalculate at some point...

 

Well you have to expect the fuel gauge to be off when you aren't on a level surface. And with 80 percent city driving 13 is pretty normal. Curious, how do you have a 4.6 2010?

 

get a 5.4 2 valve my old 03 with 124k gets around 17 most always .. worst tank ever was 2 weeks ago and got 14.7 but its 110 degrees out side and that was with a lot of idleing with ac on..

 

2010 5.4 3V FX4 with 6 inch lift and 35 inch Toyos, getting 13mpg (hand calculated)

 

Well, I just walked in, plopped down my money, signed some papers and drove off.

(seriously - did I miss something? yes - 2010 XLT SuperCab 4X2. 4.6L engine.)

 

lol

 

I'd love to get your numbers in my local yocal driving. I have a 2010 supercrew 4X4 5.4L 3V with the 6sp and 3.73 gears. Best I do locally is 12, most of the time in the 11's. Of course I can't go half a mile around here without have to stop for a traffic light. On I-95 going to Florida I've hit 19.2 for a tank and mostly get in the 18's except in winter when the winter blends knock the mileage down. Even local driving in Florida is different, a lot less stopping and starting so I usually get about 14 while I'm down there.

 

, im guessing he was thinking about the 2011.

 

i have 2010 4.6L 2V, 3.73, supercab, 6.5 bed, stock rims and tires, volant cai, custom borla si/do cat-back exhaust

my mileage has ranged from 10mpg to 16 mpg

 

LOL...I'm not the sharpest tool in the shed (used to be...but age...you know), but I kept thinking I was missing something by his question. Sometimes the "joke" is so obvious, it goes over my head.

Well, I suppose I do feel better, reading about the others' MPG averages. But, methinks some of the former statements about getting 18-19 city were a tad exaggerated!

Ah - for the days when gas was $.30 cents a gallon (oops...did I just show my age?) and flooring the accelerator didn't cause mental calculations on what groceries to do without that week!

 

My 2010 fx4 gets 13 city 17+hwy
8-12 towing the RV.

 

I have a 2010 F-150 Supercab 4X4,4.6 3V,3.73 gears and 6 speed automatic.My last 3 tanks of gas have been 16 to 16.5 MPG,8 miles to work 50 mph maybe 4 miles of the drive.

Later Mark.
