I think driving styles impacts this truck more than anything.

 

Definitely, the weight of the foot accounts for the wide variation in mpg’s.

 

Well, I drive with a VERY light foot, and I'm only getting 11-12 mpg. It's an '05 KR 2wd w/ 3.55 gears. However, I've only got around 1100 miles on it so far, and it's all around town, so hopefully it will get better with time.

 

'04 Supercab FX4, 5.4L, 3.73 L/S, 1300 miles
90% travel on highway at 75-80mph
14.2 mpg

 

I only have 285 miles but I am getting 12.3. I am expecting it to increase with more miles and also after I put on the new intake and exhaust.

I will keep you posted, I plan to keep a spreadsheet also and not just go off the display.

 

4x4 Supercab '04, offroad = 12 mpg
Freeway at 80mph, 17 mpg.

 

Yup, I dropped an easy MPG thanks to cooler temps. I'd expect to kiss another MPG goodbye as the deep-freeze moves in... oh well, snow is fun to drive in!!

:santa:

 

I've been getting around 17mpg with about 90% highway. 21k on the clock...

5.4 w/ 3.73's and 18's SCAB 4x4 FX4

my theory is that the cold air taken into the engine improves performance and causes a slightly heavier foot.

 

My 2004 5.4L 4x4 Scab w/ 3.73s averages 15.2 in mixed hwy/city driving. Freeway speeds of 70+ really kill the mpg. I got 19.25 mpg pulling a utility trailer at a steady 65 mph for 175 miles. Painfully slow, but an impressive number.

 

Yes it does. I still have about 4" to the top of the door. Just looks off because of the slant of the drive.
