Real world gas mileage

[H2forMe]

Hello everyone. I'm really looking into an H2. This is my second time of looking into this, first time a couple of years ago, and the reason I did not get it then was because I heard so many horror stories regarding gas mileage. I really want this truck.

Could you guys, real world owners and drivers of H2s please tell me?

1. What is the real mileage on them? It would be mostly city driving, AC always on (South Florida). Is it that bad? Are "tree huggers" just exagerating?

2. Do you have to put premium gas in it? Can you just put regular? I'm talking about lowest grade, I thing it's 89 octane?

Thanks for your help, as again it is the only thing that's preventing me (my wife doesn't wnat me to pay for excess gasoline) from just getting it.
