i have 1800 miles on my truck and the best i've got so far is 16 miles to the gallon. aftermarket upgrades posters welcome to post too. thanks.

 

depends on the percentage of lead in my foot...goes from 10-22...and yes, thats highway...

 

16 aint bad remember if the truck is new it takes a while after break in period a few thousand kms untill mileage is good keep your foot out of it under 2 or 2500 rpms

 

i have a soft tonneaur cover, 33" all terrains, 40 series muffler, and a volant intake. On average, I get around 15 mpg and on the highway, i get around 16-17

 

geez guys. i'm hoping to get 17-20 all day long. i got about 17.5-21 outta my '00 150 4.2L v6. hmmm... maybe if i take out all the seats, console, bed and spare tire that oughta lighten it up about 1000 lbs. haha. i wish the programmers had economy tunes to supplement the performance tunes. i knew what i'd be getting into and i know my truck is still breaking in, but damn. it seems i'm going to dropping about a 1000 bucks to "hope" it pays off in the longevity and fuel economy.
