I was just wanting know what your average MPG city/HWY is with 4.56s and 35s? Thinking really hard about doing a gear swap seeings how gas is creeping up on $4/gal. here in Florida. I do a little highway, alot of city, and I tow my boat on the weekends. Any input would be great.

 

id also like to know

 

i get better mileage in town, (13.5) on the freeway I get 12 - 12.5. If you drive 55 mph you will get 14 mpg. I have the edge level one, air aid intake, tb spacer, and flowmaster cat back. It is a 2004 5.4 3v fx4 4wheel drive.. I consider myself lucky! to get that mileage

 

12 town, 14.5 or so highway on 38s

 

x2, seeing as how we have the same setups.

 

12 city 14 all highway 6inch and 35s 4.56's

 

WTF thats bad for stock and better in town? are you saying you have 4.56 with stock tires or are you lifted

 

14MPG all around 35" tires, 4.56 gears, Airraid TB spacer, Airraid Intake, Underdrive pullies, Modular Madness Custom SCT tuner, True One chamber flowmaster custom exhaust.

 

wow thats crazy!!! I get about 13.4 to 13.6 in town and about 14 or so on the highway and I am running the stock 3.73s with my 6in. and 35s. I thought your MPG would go up if you regeared to stock configuration... HMMMM guess not.

 

I just put 4.56 gears for my 35 inch tires and Im gettin about 30 to 40 more miles on a tank.....

 

your 285/65R20s are only 34"s tall. and also a much lighter truck I might add

 

I get about 13 mixed city/highway driving.

 

Thats exactly what i get on level 1 on my edge. Try level 3 with premium. According to the edge i average 15mpg. When on the freeway i can get it up to 17mpg @ 75 mph. @
$3.60/gal 87 oct x 28 gal = $100.80
$3.90/gal 91 oct x 28 gal = $109.20

For $8.40 more you get better gas mileage and more pep!

 

I ran level 3 for about 6 months w/premium, I like the extra torque of level 1 or 2 compared to the "faster" feel of level 3. Although I will say that level 3 is faster. Yes, Iam on 35's. why the hell wqould you put 4:56 on stock tires... And yes, with these lower gears on the freeway you actually get worse mileage if you speed... (like me) but it sure moves... like the old saying hauls *ss sucks gas...

 

i get the best mpg on level 3
