MPG

I'm up to 11.6mpg. I recently switched form Sunoco to BP. I don't know if this is the reason or that the engine is breaking in. Just went over 7000 miles.

My -03 with about 46K on it or there abouts average about 11.9-12.1 each tank. This being a mix between city and highway of course .. and I fuel nothing but BP if I can help it!

damn I get 8.5-10...wait I have an h3...CRAP

You have one bright side to the piss poor milage Mike...Once you're ready to trade up to an H2, it won't be a shock for the fuel mileage and you'll actually appreciate better mileage..so it's a win, win!

true, except I wouldn't say that buying an h2 after owning an h3 is "trading up" Like I said, my dually got 3-5 mpg so mileage really doesn't bother me that much.

I'm getting around 11 in town with 8000 miles I did avarage 15.6 on a trip to SC and back.

9.5 around town and just returned from North Carolina, got 15.2 @ 75mph.

I just got to 39,000 mile and get 11.9 on my 05. Does the check engine lite come on when it's time for an oil change? PLEASE tell me "yes". I have 20% oil life nd my check engine light came on.

I don't think the engine light comes on for the oil change. You must have something else going on. Still under warranty?

No... No warrenty. Maybe "service engine soon?" At almost 40,000? I'm gonna get it checked out. I'll let ya know

Check engine light was gas cap not being on tight. Called OnStar... the tech diagnosed a emmision problem. After speaking with him, he suggested I check the gas cap since I had just fueled up earlier in the day. and Bingo. Problem solved!!!!

Good to hear

That was an easy fix.

When I had my 24's on, I was getting 12.4MPG 15.9MPG on our last trip to Minneapolis!!

Now the OEM tires are back on and WINTER driving and RUNNING my rig to warm it up...10.4MPG

COME ON SPRING!!!!

I am primarily going to be using the H2 for city driving, highway also but more city. I'd say about C:H => 80:20. What kind of mileage can I expect? Also, this is a used 03 with 40k miles on it.

My current car is a Subaru Legacy GT 2.5L Turbo. I get around 190-220 miles using 93 oct. on the 16g tank for mostly city useage. Will the H2 give me something similar to this on the 87 octane?

I'd say expect anything between 10/12 mpg in city .. at least that's what I've seen on my -03 with 45K on it .. this based on 89 octane ... I think the fuel management states 320 some miles out of one tank but I'd say it's closer to about 300 based on what I've seen in mine. 

i just trailered 4 snowmobiles to upstate new york from here in southern Pa, 357 miles one way , I have an 03 with 67000 miles. I got 6.5 miles to the gal. LOL
 
Im glad we all split the gas every fill up!

Holy hell LOL!  I bet the trip was worth it though .. I miss the back country snowmobiling from my teen years back overseas ... little difficult doing that around the cornfields here in SW Ohio LOL!!!!

it was awesome ! the trialer was a 24ft car trailer. LOL
 
The h2 pulled awesome, those mountains killed me with the gas.
 
O well it was blast!
 
well worth it!
Will take the tahoe next  time though with two up trailer.
Make the other guys take their rides with trialers!!!!!!

I'm definitely jealous here :-)  Crappy mileage or not .. Tahoe!?  I wouldn't think the mileage would differ much at all between the two .. granted, I guess its a few lbs lighter but ...

yea we went to New hampshire last year with two up trailer and got like 13 miles to a gal , Rolling about 80 the whole way!!!  
 
We did close to 400 miles all said and done on sleds that weekend!

I don't miss that place a whole lot but when it comes to things like this .. I do have to admit there were SOME benefits to living over there I guess .. the backcountry snowmobiling being one of them ... and flying gliders in the mountains *sighs* ...

Hi everyone! I also have a 03 H2 and started to track fuel use in Sept last year. 35569 miles on my hummer currently. Best MPG was 13.946MPG on a weekend trip to Universal in Orlando. The worse was 8.178. The truck mainly sits now, used on weekends mostly. Was my wife's daily runner until gas hit $3+ last year and we decided to buy a roadster. The fuel saved pays the the 2-seater and fuels it-- If I average the MPG over the 5 months it comes to 10.7597MPG--

I got up to 12.1 mpg over the weekend. Just rolled over 45,000 on my "05 SUT

Guys (and gals) - I love the trucks, especially the H1's.  But this thread makes me hurt.  I've got about a 24 mile commute to work.  So, at nominal or slightly better mpg for an H2, I would use 2 gallons to get there and 2 gallons to get back.  4 gallons.  Which at AL pricing is about $10 just to get from work to home.  Not counting lunch trips.  I guess it's just a matter of perspective.  My perspective is commuting in my Corolla and grannying it to get ~40 mpg.
 
Don't get me wrong, I'm not bagging the H2.  There's a new one that just showed up in the parking lot, and it looks fantastic.
 
Also, from time to time, I put together a side job.  A haul.  I'll transport *something* from near where I live, to any particular place.  And then from near that particular place, I'll pick up *something else* and transport it back toward where I live.  I can make anywhere from $1,000 to $2,000 on one of these weekends.  I use my Cummins Ram and tow a 24' enclosed trailer.  During this haul, I try every trick in the book to get 13.5 mpg.
 
I run 65 mph on the interstate in 6th gear, to use less fuel.  Like I said, I target 13.5 mpg, but usually wind up averaging right at 13.0 mpg.  I'm usually towing anywhere from 5,000 to 10,000 lbs. depending on what's in the trailer.  That's a GCW or 12,000 to 17,000 lbs.  And the truck tows that with ease, pulls up hills without needing to shift.  The truck is modded.  Dyno'd at 315 h.p. / 660 ft. lbs.  It's a heck of a truck.
 
I really like the H2's, and the H1's even more, but will have to just admire them from a distance I guess.
 
Love the site, and a good informative thread!  Thanks.
