New member here, first post.

I'm thinking about buying an H3 before the end of the year. I'd like to know what everyone is getting in real world driving for gas mileage.

My driving will be about 70% highway/30% city. I'm religious about cruse control set to 68-70 on the highway.

if your not heavy on the throttle, it actually gets pretty close to the manufacures stats. I've an auto and I'm getting 17 plus in mixed driving. I do seem to get better economy using the midgrade fuel... and it runs better I think. Though 87 octane won't give you any problems either.

Well, I have had mine for about a month and I get between 300-320 miles per tank @ 23 gal/tank ~ 13.5 mpg. I drive about the same ratio as you.

That is what is so strange... such a difference in fuel mileage.

Thanks for the replies (and keep 'em coming).

I just finished my third tank, and got 13.7 in pretty much exclusive city driving. Good news is that so far it is improving by about 1 mpg per tank of gas as it breaks in. Hoping it will settle above 15, but I can live with 13.7.

Averaging 15 mpg in suburban driving in Silicon Valley (mixed city and fast freeway driving).

I check my mileage almost every fill-up, and I have about 9000 miles so far. I use Chevron regular.

Low=14mpg
High=18mpg

I should probably quantify my earlier remark as well... I try to keep the rpm's at 2000 or less. wich is around 60 to 65 mph. So its with fairly benign speeds.

I've been averaging around 15+/- mpg over 7300 miles. That's in crappy Bay Area traffic and I've got a heavy foot.

Thanks everyone.

This afternoon I rented a base H3 with auto to see what kind of mileage I'll get over the 24 hours. This rental has 4k miles on it so it's still "new" but we'll see. I just got back from driving around a bit in my area.

Two comments after my first hour in the H3:

1. Rear window is useless; can't see the car behind me - especially if they're drafting.

2. I've opened the hood once already; meant to release the parking brake, grabbed the wrong one.

You get used to the rear visibility, its not that big a deal... the side mirrors are much more useful in reverse anyway. And the parking brake thing kinda funny... I must have hit that damn thing like 3 times test driving, would drive a h2 and then drive the h3... and forget... couldn't make up my mind... but you get used to that as well... I'm very happy I ended up with the 3.

1. Yep. Although it's a little better with the back seats down. You might also be able to adjust the rearview mirror up so it has a better angle looking out the back.

2. Done that several times myself.

1. I had a hitchcam installed a few weeks ago, seems to help when backing up.

2. I did the hood release once instead of parking brake.

I do a mixed amount of driving to and from work and at 6K I am averaging 17MPG I did a road trip and on the Highway I got almost 20MPG which I was most impressed by although it was a fairly flat stretch of road we were driving.
I have noticed that I am getting better exceleration since I passed the 5K mark. Maybe its just me but then again it was my wife that mentioned ot me first.

So far after 800 miles of mixed driving, I'm averaging 17.1. I have the Adventure Package.
