i got 18.436 MPG on my way to louisiana friday night.

mods:
35" tires
vmp tuned xcal (was running 87 performance)
intake
3.73 gears

i beat my old record of 18.1 last year

 

pshhh i eat 18mpg for breakfast

 

I got 18.7 on my last trip to the outer banks. 5.4, 305/65/18, 3.73, troyer tuned xcal 3, af1 intake, and muffler delete. Im not lifted though so that helps some.

 

I need a tuner so bad.

 

makes me happy i'm trying to work a tuner out with PHP. Hope I can get close to that!

 

Nice. Ive gotten a best of 15.8 with my totally stock '06 5.4 Supercab 4x4.

I took a highway trip this weekend doing 65-85 and still got 15.8 which is the best my truck has gotten.

It seems like if Im on the gas or drive easy the mpg is still the same.

 

are you using the MPG listed on your dash? or calculating it by hand?

if i do anything above 70 my MPG drops off significantly.

 

I just beat my all-time record on a trip out to northern CO. 23.9 MPG @ 68MPH.

My new tonneau cover is adding almost 2 MPG.

 

alright, well no one asked you

jk. congrats, i wish i was getting that good, but that will never happen unless i got a good tail wind and can put her in neutral. my dad and sister get 21-22 w/ their edge and gryphon occasionally going about 65ish.

 

Im calculating it by dividing the miles on the odometer by the gallons I put in.
My truck doesnt have a dash computer.

 

21.3 from Annapolis to Charlotte


That was a slow trip...

 

So far city, my best is 16.59mpg all stock perforamance wise except 14" maggie si/do

 

I somehow managed to get 17.5 towing a loaded uhaul trailer from northern cali to southern cali. That was with going thru the mountains.

 

My 06 Screw XLT I bought last week gave me 16.8 on my first trip over the holiday. About 40 miles around town and 200 miles at 75 MPH.

I was pretty satisfied with that, actually better than my last trip at similar speeds with my 4Runner.

3.55LS 4x4 with tonneau cover.

I got 11.8 mpg on a 200 mile trip but I was cruising 85+ the entire way, lol.
