I'm not disagreeing with you standing up for yourself but, given what you've just said, you of all people should not be comparing the moderators to Nazis.

Sorry for the hijack. Although I haven't done an extensive workup on the gas mileage of my H3 since I'm only on the second tank since I bought it, I've observed appx 16 mpg in mixed driving; appx 50% highway and 50% city. My H3 has a K&N air filter and an aftermarket dual-pipe muffler which likely affect it's performance.

That's what I get when I drive the speed limit with a tail wind!

I get roughly 360 miles before the light comes on.

Thats very good and likely very near the best most of us will get.
I have gotten (once) 351, but mostly 290 to 320.

Overall I average around 15mpg

the majority of my driving is highway with less than 5% being city. Before I had to have engine work done- I honestly used to get close to 380 miles before the light would come on. However, for some reason- ever since the dealership replaced the cylinders- the gas mileage isn't quite what it used to be but it's still pretty damn good.

Wow 360 miles before the light comes on, probably about 18mpg, pretty good. I've only seen 18 mpg once in my H3. But my long freeway drives in California usually involve speeds in the 75-90mph range and the mileage never exceeds 17mpg.

From somewhere on the KS turnpike to Vandalia, IL is 365.90 miles, and that is when I filled up with 20.007 gallons this July. (18.288 mpg) Could have easily gone up to 400+ miles on the odo.

I drive 100% city. First tank was 11.2mpg, the second 13.5mpg. I drive my H3 like I drove my Z4...but worse. Now I can driver over things in my way.

I just installed a K&N CAI and got the PCM mod'ed by pcmforless. We will see what happens.

Ok just filled up my first tank of gas today i had 250 miles on the car and the tank fills up 20 gallons so myself on my first tank i got 12.5 MPG. Maybe once the break in period is done or what not, hopefully I'll get more MPG

I can get around 340 miles before the light goes on. Most of the time 320. I would say I avg 16.5-17.5 at best.

I just filled up for the second time and got 15.6 mpg. Does this get better as the H3 continues to break in?

My observation is the same, mileage doesn't get much better after break-in.

Some people have reported 19-22 on a nice long road trip, no mountains, no hills, cruise control, 65mph and lower, etc etc...

In real life even after your first 500 to 5000 miles you will see 12 to 18 mpg depending where you live, your top speed, use of cruise control, HOW HEAVY YOUR RIGHT FOOT IS, etc

I have around 12000 miles on my yellow one and 3000 on the gray, both are averaging around 15mpg.

Thank goodness we can burn regular gasoline.

I have the adventure model, and I average 18 mpg all day long. I do not check miliage with every tank, but I have checked 4 or 5 tanks and it averages 18 everytime. That is mostly highway, and little traffic.

Wow 18mpg, must be some slow highway speeds. Takes more self-restraint than I have to drive that slow. I've only seen 18 mpg once in 29000 miles of driving my H3. But freeway speeds in much of California are 75-90 mph.

I guess, I usually cruise the hwy at 70, if that is slow.

70 just feels like the right speed for the rig rpms are about 2200,
and it doesnt have to work hard to maintain it.
