Mine 2005 F150 std cab 4x2 65k miles 4.6L 15-16 city/hwy combo 17-18 hwy
been tracking milage since Jan 08 on this truck ( i have a heavy foot at times too)

PS Dave when your ready to look at buying one,,, know a guy 2 miles from the shop that can get you a wholesale deal...

Good luck

 

My 05 4X4 with 3.55 gears and 5.4 gets 12-13 mpg city and 18-20mpg highway at 65 mph. I also got 14 mpg on 600 mile trip pulling a car at 60 on a car dolly.

 

I get 14mpg 6o% hwy driving debating trading her in

 

yeah thats a 2wd 3.55ls 5.4 3v

 

i get 15-16 city and 20 hwy and i have a heavy foot.... that's canadian gallons though
so 13-14 city and 17 hwy american, but like i said i'm not very nice to my truck... she takes a beating... that's with the mods in my signature... dunno if it mentions tires in there but i've got 33.2" 10 ply (e rated) goodyear silent armour ats

 

Dirtydog, what tune do you run your edge evo in? I have one in my 08 harley 5.4L but I can't seem to find the best tune. Any help would be appreciated.

 

oh yeah sorry... i always run 91 octane and always on level 3... tried going back to level 2 and 87 octane but i lost 2 mpg, so i figured i'm paying 8% more for gas and getting 10% better fuel economy.... so i stuck with level 3

 

Wife says I'm antsy about the new (to me) truck and I'm filling it up every other day or so.....BUT, gas at one location was $3.44 and everyone else had jumped to $3.56, so I pulled in a filled up. 13.197 mpg on 100% stop-n-go in town which is just about exactly 2 less than the Ranger V6 and I'm a whole heck of a lot more comfortable! Oh yeah, 05 Supercrew 4.6 stone stock (but about to change!) I'm anxious to put more than 1/2 tank through it--combo driving and see what she does....

 

I bought my 05 in December 07 and have kept each tank by hand. I always use 89 10% ethanol because it's $0.10-$0.12 cheaper unless noted otherwise.
I drive 15 miles to work one way and once a week I drive 30 miles to a different location. Altogether, I do about 60% driving on the highway, 40% in town.
bought truck 12/20/07

SO, since 12/20/07, I've driven the truck as of last fill 5,472 miles and used 412.8 gallons of fuel for an average of 13.26 mpg.

 

That's a good log! Will help with questions that have come up regarding mods.

 

2004 Stx F150 4.6l Auto 3.55 Gears
True Dual Exh From The Cats Back
Supercab 6ft Bed
15 City / 21 Hwy
No String Pulling

 

I Also Have A Heavy Foot !!!!!!

 

I have a 2007 4x4 5.4 and just got 381 miles and had to put 26.2 gallons in the tank. The cost for the fill up was $96.27. I still love the truck! I think.

 

I average high 18 to 20 highway at 70 mph slow down to 60 mph will get 21 22 mpg
and 13 to 14 city

 

Thanks Mike! It's an idea I am thinking about but just not sure yet. I appreciate it, I'll let you know.
