22 running interstate (thats with a couple WOT pulls)

around 15 in town.

 

my cluster says 15.4 average between highway and street....... i mostly drive in streets

houston to mcallen roundtrip around 700 miles.... i made it with 1 gas tank

 

32 ish mpg...

 

only time i can pull 32mpg's out of my 6.0 is lettin off the throttle going down a steep hill...how the hell did you pull off 700 miles on one tank? Im averaging 12.5 city 18ish highway with the 6.0 and awd.

 

my 2006 ECSB 5.3/4L60E gets 10.0mpg when i rip on it all day long, 12.5mpg with hard city driving, freeway trips i get it to around 18mpg.

 

its not 32mpg..... how big are ur gas tanks ??? mine holds 26 gallons.... that being said 700 divided by 26 = 26.92... and i topped it off a lil more sooo i say around 26mpg... goin around 60-65mph the whole way cruise control, no load, 3.73 gears on some 31inch tall tires.

 

mines a 26 gallon also, but with a 6.0, 4.10's and awd my gas mileage doesnt upset me too much, haha. i also never do 60-65 on the highway, its usually 70-95, more if i find someone who wants to play!
