The '07 5.3 2WD never averaged better than 18, but would do 20-21 on the freeway in and out of V4 mode. My '09 6.2 4X4 has intake, tuning, and thirst. Never had 4/8 mode and never did better than 12 mpg average stock. Even now, the only way to get 20mpg is to find a hill and drive down it. With mods, 14.6 avg.

20 mpg

I get 15 avg with the 6.2 in a 08 denali. I got 16.5 in my 06 envoy xl with the 4.2 I6. I have been thinking of getting a tuning computer do it can run on reg unleaded.

The best I could get on my trip over the weekend was 18.5 on the interstate going to 75 mph. 5.3l stock wheels :bawl:

We drive army tanks. They were not designed to have high mpg. But to haul lots of people and toys and trailers and be large and comfortable.

Honda fit is designed with one reason. High MpG anne is useless otherwise.

I'm only on my third tank of fuel for the 08 (5.3, 2WD). First tank- lots of stop and go was 17.5 mpg, second tank - interstate and 2 lane highway through the rolling hills of VA - an amazing 21.1 mpg. Third tank is showing an average of 19.5 right now but I'll see what it really was when I fill up. (all mpg is calculated at fill-ups, not going by the computer)

My 02 4.8 2WD got an average of 17-19 consistently (mostly highway). I think the 08 doesn't have to work as hard and spends less time going in and out of overdrive.

I have to keep the info center off of "average mpg" It drives me nuts watching it.

Added - 18.5 mpg on the third tank. Not bad... I am not hypermiling either- I keep up with traffic (or go slightly faster, usually 4-5 mph above posted limit), people aren't waiting for me at traffic lights- I accelerate normally...I just don't floor it, coast to stop signs and red lights instead of keeping it on the gas all the way until you have to hammer the brakes....

My buddy rented a Suburban while visiting Denver, he got an avg. of 19 mpg supposedly...
This is possible out in Colorado..we have a NBS Suburban that stays out at our vacation home in Steamboat Springs and is driven up and down a highway that you continually go about 45-55mph and it averages 18.5. I have also done it in my NNBS Tahoe, but never got above that 18.5.

I average 15, mostly around town driving and maybe get up to 17.5 on the highway.
Honestly, 20mpg seems a little too far out of reach for a non Hyhoe.
