Re: MPG 20 or not
RYD - I was counting on you not believing, took you long enough BTW. You see, I was hoping to get you to come up here to help me move under the cover that you would be my MPG Monitor Patrol. So, now that it's out there, how 'bout it?

Re: MPG 20 or not
With the Toyo 33" tires, I have been averaging about 15 on the highway with an automatic. Mine just went over 7,000 this weekend.
I have given up on mpg for now, but love my tire look

Re: MPG 20 or not
You may get 20 mpg if you have the manual, and you don't go fast on the freeway. Car and Driver magazine reported that the H3 has a coefficient of drag of 0.51. That's awful. The FJ Cruiser is 0.40, and the LR3 is 0.41. A BMW X5 is only 0.35. What this means is the H3 is going to have a lot of aerodynamic drag at the higher speeds, and your fuel economy will plummet. Drive slowly, and get the transmission in 5th gear as soon as possible for best mileage.

Wish I could go slow on the highways.
From where I live in Montana, I can go east for 3 1/2 hours and get to my Hummer dealer and not be near the eastern border of Montana.
From where I live in Montana, I can go west for 3 hours 20 minutes to our cabin and not be near the western border of Montana.
And this is doing 70 - 75 miles an hour, going slower would take forever here unfortunately

Re: MPG 20 or not
My experience confirms what everybody else is saying. I have just over 8k miles and average 14-15 mpg, although there have been tanks that I have made over 16 mpg. I assume that I would get better mileage if I had a longer commute to work, but I will take that mileage over a long daily commute!!!

Re: MPG 20 or not
Yeah, when you start going 75 and over it uses more gas. It's the big hole it leaves in the air.

Re: MPG 20 or not
Maybe I?m anal but I have tracked my fuel usage from the beginning. I now have 21k miles, live in Phoenix so the A/C is on all the time, four wheel frequently, drive 5 to 10 over the limit, have 35? tires and it?s an automatic..
Min 8.07 mpg (four wheeling in Colorado).
Max 20.07 mpg (on the way back from Colorado)
Average for 21k miles 15.06mpg.

Re: MPG 20 or not
well it depends where you are from. America doesn't have the highest grade of gas. Yes people from Mexico may have terrible gas, Canadians have the top in North America. If you fill up with some Canadian gas, you'll probably get over 20mpg.

Re: MPG 20 or not
Last weekend we drove from the LA area to Sedona AZ and got 17.9 mpg averaging 65+ mph with the a/c on. That's for an automatic with 5000 mi., Adventure pkg, brush guard, roof bars and std tire pressure on a route with a lot of long grades.
Based on that I think I could get really close to 20mpg if I turned off the a/c, upped the tire pressure and drove with max economy in mind; maybe even more.

Driving across the desert when it's 110 with the AC off, to save gas. I wouldn't do that.

Re: MPG 20 or not
21 mpg doing 45-55 mph.
16 mpg at 65
15 mpg at 75
12-14 around town, short trips during the week.
This is with a loaded AT Luxury.
Realize that ethanol has a lot less btu/gallon than gasoline, and a 10% blend will drop your mileage 1-2 mpg.
Do not use E85 of course in a 2006. I don't know about the 2007s yet.

Re: MPG 20 or not
I got 20.1 MPG highway today at 65 MPH. I got 19.1 MPG Highway doing about 70 MPH, and this is an automatic, not stick shift. Otherwise it is about 16 MPG city. But take note that I have about 6000 miles on the vehicle, so it is pretty well broken in by now.

Re: MPG 20 or not
I get 19 - 19.5 back and forth to work very little stop and go 35 miles 1 way. I have almost 25k on the little monster and check my mpg every tank full.
