That's what makes me reluctant about installing 4.56's. I have a set in a box that I am debating on installing, but I like my gas milage the way it is thank you..

I love the way the 4.56's launch, but the mileage is killer:rock:

The worst i've ever got was aroung 8 mpg, my first tank, and the my average is 10.5, hand figured. My overhead read about half a mile to a mile better than the actual. On the highway i got 12.5 hand figured.
 
A bit over 19 on the highway is common. That is a pen and paper calculation and not the overhead.
The mileage went UP after the cam and Strikers were installed.

We also have a bit bigger gallon here in Canada...

The mileage is better than my 1999 1/2 ton Dodge 4x4 bush crasher, with the mighty 318.

Some real good numbers here guys, I might have to drive for the best I can get and see what I can run. My reading was normal driving, overtaking, floor it when I want, etc. Good to know when you need to, these trucks "can" get some decent (decent = in performance vehicles) MPG figures. :)
 
Never checked mine much on the 4.10's

The 4.56's gave me 18.9 going to PCB gtg running no more than 65mph
Going to and coming back from Macon I averaged 15.4 running 78 mph

When I get the 4.88's in well, mpg will go down a bit :mad:
but for around town :D
 
14.3 in the summer, 12.2 in the winter... anyone else notice a different either from warm to cold weather, or is it the winter blends of gas????
 
I was getting around 14.6 just playing around town. Most the time I'm a laid back driver, I get on it at the green lights, but drive fairly conservatively usually.
 
Just drove from DFW to SW LA driving around 85-95 got around 15.2:D
Im not arguin with gas only 1.65 for 93 octane
:rock:
 
Just drove 900+ miles from VA Beach to S FL on the new Roe Whipple install and the highest reading I got was 18.4 @ 80 mph. The lowest it read was 3.8 racing a twin turbo BMW with work done to it. Reading was taken @ around 170mph.

170 in a 6k pound truck?? Bro you got some balls. :rock: :rock: BTW did you win??
 
Yea I'm getting a little old for shenanigans like that, but it was 2 in the morning just south of Orlando on I95 with no other traffic. I talked with the guy at the gas station and he got on the high way behind me, we drove for like 10 minutes with him like a 1/4 mile behind me. When there was no traffic I sawl him coming up, I was rolling around 80 and didnt hit it until he was next to me trying to do a blow by. he got out about 4 car lengths and I blew by him @ about 145 and stayed in it till about 5400 rpms.
I've been street racing for some time now and know all the consequences.....believe me. 3 suspended liscences later! :rock:
