Just finished 3000 mile trip, returned towing car on 2 axle trailer & light load, maybe 500 lb additional cargo. This F150 extended cab has had every tank logged & just turned 55,000 miles.

Empty the best MPG it ever got is scarcely over 16. Hauling this load on interstates going 70-75 MPH it got just over 12 MPG.

 

I don't think that is too bad....a buddy of mine with a 2000 & 4.6 usually got 8-10mpgs when he pulled is camper and 16mpgs as DD.

I get about 15-16mpgs as DD....I have the 5.4. recently I took it on a 1400mile round trip empty ...er' nearly so...mmm suppose 1000# under the tonnue cover on the way down....much less on the way back. WE managed to averaged 17mpgs round trip....same interstate speed as you. And have 164k on mine...you should have a lot of happy miles ahead

do you have the 4.6 or the 5.4?

 

Sorry, swear I posted 4.6

Not sure how big an MPG penalty hauling around 4X4 system all the time might be?

 

Same truck with 8'box. Has a 200# ladder rack, tool boxes, ladders, tools....maybe 1000-1200 pds. as constant. I get about 13.5-14.25 in the summer in a mix of driving. But most days it may have another 500-600 pds. in it. I keep it at 62 mph if on the freeway and never any WOT stuff....maybe once a month or so to pass. Even in the dead of winter it has never fallen below 12mpg. I just recently went to Illinois and back with about half of that 1200pds. removed .....drove 65-68 mph on cruise with air on all the time and got 16 mpg.....that is the best I have ever got. I have 240,000 miles on that 4.6 and it's kinda' sad because the underside is just plain rotting away. I noticed the ladder rack was hitting the top of the cab sometimes. Here the front support for the box underneath was literally eaten away. I bolted a big piece of angle iron in its place.

 

I have a 2002 F150 Super Cab with an 8' bed and a ~300 fiberglass cap. In the winter I usually get ~13 mpg. In the warm weather I get ~15 mpg. I don't tow or carry lots of weight much any more. It's a 5 speed manual with the 4.6. All our gas is 10% ethanol. It doesn't seem to matter if I drive all highway or the usual secondary roads. My drive to work is 9.6 miles each way at 45 to 50 mph with a few traffic lights.

I'll echo Whimsey and Spotty on winter MPGs

no worries....but I really thought I mentioned mine was a 4x4 earlier too...so I swear I posted that lol

 

My 98 f150 supercab 4x4 with a 4.6 gets 17 around town on 10% ethanol. I need to check it aagain since I started running 100% gas
