I have been curious since I bought my 03 about actual gas mileage. I had averaged 10 mpg around town and going to work. I drove to Kansas City from Oklahoma City this weekend and it took one tank of gas. The low fuel light didn't come on, and I got 335 miles on 20 gallons of gas. That seems to be 16.75 miles to the gallon. Is that what everyone else with a STOCK L gets on highway trips? BTW not much headwind to speak of either.

 

I usually average about 13mpg with some mid-high 12's running around town. Highway about 16mpg. Believe it or not I have gotten a little better gas mileage since I had the 4lb pulley installed a few months ago. I don't know how but I'm not complaining!

 

ive never gotton worse then 13 avg on a tank

i also drove a tank making sure not to move the boost needle and only got 15.5

 

i get 10 around town and 12 on the highway with just straight pipes and an intake. I drive it like i stole it though!!! I could probably get better but i have never really cared to try.

i get about 11 in stop and go but got 17 on a 40 mile trip to ohio

 

Just drove a 260 mile trip and got 16.5. Started in L.A. and drove to Big Bear Lake 6750 ft. elevation. Went 80 on the frwy and was stuck in traffic driving around the lake to watch the fireworks. I think that I get better milage with the chip, filter, t/b, and the k/b than I did stock. Skip

 

i wonder how much the gear ratio matters mine is a 00 with the 3:55's mabe that is why it is slightly better?

 

Mine is a 99 with 3.55s. The people that I know with 01s and up seem to get less mileage. Skip

 

My '03 with about 1,700 miles on it has just recently cracked 15 MPG in rural driving. I was getting about 14.4 when I first got it, and I have not been driving aggressively.

 

Now this is one area I don't understand too awfull much?

I do drive pretty easy most of the time. But try to get a bit-o-boost everyday. You know more quickly accelerating than everyone else around me.

With the mods in my sig i'm avging 16.75 as of late. The worst I got was 14.99 and the best was 18.8 out on the interstate.

I really do think that these trucks stop and go so effortlessly that people tend to drive them like a little econobox car. Fact is these things are porkers! Just lay off the brakes and let up off the throttle sooner.

: old man steps down off soap box: WOT

 

I get around 10 mpg in city driving. i have a 2000 with chip intake and its lowered, thats about it.

 

Anyone one know the worst they have ever gotten, I'm talking about modded one of course.

 

I might have the reord, Iget about 9.4 city and 10.8 highway...but this will get better when I install my Kenne bell and 55# injectors...Pete

 

best I got was 18.4 coming down from Mt. Shasta on the way up here with a ton of stuff in the bed. I think the best level I got was around 17.5mpg. Then again I do have a '99 and longer gears.

 

thats impressive but do u drive it like you stole it?
