[NJHummerGuy]

Just got my tank filled up for 1st time since getting the new wheels.....got 18mpg!
What are others getting?

[The Green Lantern]

- city 12-14 mpg(supreme), highway 16-17 mpg

[DarthKarl]

I get about 14.5 mpg city and 17.5 on the highway.

[wannabeH3]

seems i get 14.5 everywhere...

[NoMoGMPG]

You all must wear steel shoes! I get 14mpg in my H1!

[fourfourto]

Normal driving cty/hwy avr 16-17 mpg
little hard driving 14-15
baby it on highway w/cruze 1/2 the time 18-19.

18 MPG MOSTLY HIGHWAY

H3-o Hawaii
How come the H1 highway in hawaii is considered a interstate .
Also How much would it cost me for a small house in hawaii. i just might retire early and Hawaii could be the place (As long as i can get my H3 and 442 and bikes over there

I'm up to 4500 miles now, and I've checked mileage on every tank. Best has been 18, worst 16. Almost all were right at 17. Mixture of highway/city driving, but not a whole lot of stop and go traffic.

There are three interstate highways on Oahu. They will connect to the US when Hawaii becomes a state (jk). Avg prices are in the $500k range.

BTW I am getting 14 mpg.

14.5 miles city with 20 inc wheels

[PCBeach]

Automatic..Was doing 19.5 Hwy and 15.5 city..changed to Mobile 1 at 3000 miles.. Now with 5000m getting 20Hwy and 16 city.. Oh yes its flat here in the Florida panhandle and I am old and slow!!!Have checked every fillup.

[psywzrd]

I've yet to break 13mpg. I know I have a heavy foot but that seems a bit low to me.

[HummerJim]

Yep, 28,450 miles here and a consistent 18 mpg on the highway - mostly all highway lately.

There's a difference in MPG with the base and with the adventure package. I was getting around 18-19 with the base, 16 with the adventure. Must be the tires. The base also accelerates better.

[fourfourto]

Its funny how they dont rate them differently. I wonder if they ever tested adventure mpg or
0-60 , 1/4 mile times ,braking ect.They probobly based all info on lux or base

All - I'm getting a consistent 15 mpg in mixed suburban driving around Silicon Valley. I've only done one coastal highway trip (not all freeway) and got 18 mpg.

Hummer Jim - what speed did you generally cruise at when you got 18mpg. I plan to take some road trips later which means cruising at 80 mph in central California. What type of mileage should I expect?

firm - I'm not surprised that the base accelerates better on the street (in high range) because of the significant difference in tire diameter. Of course in low range the adventure package will accelerate and climb better because of the shorter gearing.

Is it better for gas mileage to use the cruise control or not? Also, how are you guys getting different numbers for your highway and city driving. I do a mix of both, so it's hard to estimate when I check my mileage at fill-up time.

It all depends on your driving habits. The cruise control will generally want to down shift a lot in order to maintain the speed that you have set (that’s of course its job in life). This is especially true if you're driving on a hilly road. If you're looking for MPG over constant speed, then you're better off by controlling the accelerator yourself and letting your speed drop down on inclines (and therefore not down shifting as much as the cruise control would otherwise do). If you have a heavy foot on the highway (never letting your speed drop below the speed limit and downshifting a lot), then your MPG could actually be better with the cruise on.

Steve San Jose - I can tell you from my experiences in the Yukon where the roads are long and straight and the traffic is sparse that cruising 65 mph you will get in the 18s on flat pavement and crusing 80 mph you will get in the 16s - wind resistance is a big factor and the frontal area creates a lot of drag- induced and parasitic. My best ever was north of Whitehorse on the long (95 miles?) gradual downhill straighaway with a brisk tailwind running 66 mph with the cruise- an honest 20.2 mpg. I have the base, and I have heard mileage is not quite as good with the Adventure. I had so much fun up there I'm planning another trip only earlier in the summer for 2006 - late July probably.
