city: 16-17
highway: 18-19

when my truck was new (<5000 miles) it got about 15 city, 17 highway, but its steadly gotten better, as has the shifting quality of my tranny. i now have about 18,000 miles.

 

THAT is a big part of it..

I have 3.55 w/4x4, that has to contribute to bad gas mileage..

but man, this truck sounds meeeeeeaaaan now

takes off pretty damn quick too

 

I usually get 12 to 13. My higest was about 17.3 on the highway. i dont even try to keep up anymore. just fill her up and romp on it.

 

I'm getting 16-18 city 20+ highway

 

I just figured it out, after my weekly fillup today.All city driving I got 14.5 mpg, not bad but it could be better.I do have a rather heavy foot so I know that it would be if I didn't get on it so much.My highway (last time i checked) was around 19 mpg on relatively flat ground.My all time best was on the way home from a hunting trip in the mountains last fall...........24 mpg, it was downhil all the way home.My gas mileage has steadily gotten better since I broke 15K (I now have 25K)

BTW, my truck is a 4x4 reg cab with the 3.55 rearend in it (only a Jet air filter)

 

15 mpg city 18 highway 20 best

 

In winter time in city 13.5 highway 17.0 summer time city 14.5 to 15.0 highway 19.0 mpg because of fuel change. 98 ext. cab. aut v-6 pushing 209 hp with 4.10 gears and 33 in. tires . dan

 

My 4.2, auto, with 3:55 rear gets 15 - 16 City and 18 - 19 highway, without running the air I have gotten 20 mpg on highway, but only once.

 

Just got back from a round trip to Austin Tx.. Got my best tank yet. 21 mpg. couldn't believe it. I usuually average 18-19.

 

I filled up my truck thursday night, my mileage was 25% town,75% highway,I got 17.5 mpg canadian which works out to about 15mpg in the good ole usa.

 

I usually get 15-19 but on a drive from Lubbock to Houston - mostly flat, with the a/c off (only Panel) and going 70 I got 22 mpg. I think the gas mileage tends to suffer after 2000 rpms

 

My alltime high was 19 mpg.
Alltime low was 15 mpg.

 

15 long distance stop-and-go, 15 city, 21 highway

 

I filled up yesterday. I wasn't totally empty, and I had over 360 miles on my tank, so I thought I was going to break 17 or 18. NO! I got 16.6 on that tank. Granted, it's all city driving, but it's not like my truck is fast or anything. I don't drive with a leadfoot. One of these days, I'll have to take a roadtrip (with the wind at my back) so I'll feel better about my mpg...

 

I bought by 99 F-150, extended cab, used about 4 months ago. It has 80k on it. Automatic with 3.55 gear. Gets about 19 around town and 21 on the highway. So far, been real pleased with the truck. Put a K&N filter on it and use Mobil1. Looking to put a limited slip in soon as I can scare up the money.
