New H2 Owner dumb question

[dkhummerh2]

Hello All,
Just purchased my first H2 last week. I looked for months until I found the best deal that I thought I could find. I ended up buying a 03 H2 with 40k miles on it. It has a whipple supercharger, corsa exhaust with everything else basically stock. I love it, nothing else compares. I am only 28 years old, so I of course drive it daily, mud it nightly. As far as the highway, I am looking to get the best mpg possible. Any suggestions on improvements? Is the supercharger killing it. My instant mpg on the highway is at 14.5 miles per gallon. What are you guys getting?
thanks for you help

Nice. We got 5 inches of rain 2 days ago, taking her out to the lake this weekend for some trails, post pics soon

I have an 04 H2 and very rarely have seen 10mpg. About ready to install a magnuson supercharger in the next few weeks, so with your supercharger getting 14mpg, I would be a very happy camper. by the way, how is the whining sound on your whipple s/c? I wish the magnacharger would whine on idle but it only does so when you kick it in..

I have pretty much the same setup. You are doing great to get that mileage S/C or not.

The best thing you can do is just forget about mpg. This topic has come up multiple times and no matter what you do, you might be able to squeez 1 mpg more if you lucky, on anything you do. If you keep looking at the "instant mpg" gage it will drive you insane. This truck is a shoe box going through the wind so forget about it and move on. Just think about "I HAVE A HUMMER AND YOU DON'T" that makes it all better. Thank you and good night sir!

It sounds sweet when you get on it. I don't really notice a whine on idle either, but the long first shift gets the exhaust sounding amazing. As far as the 14.5 on instant, I drive down the highway at 59 miles an hour. After all I have a Hummer, honk I dare you. I had a Lincoln Navigator that did crappy on the mpg's too so it's not like it is any thing different than what I have been used too. Does anyone out there have nitto mud grapplers? Just wanting to know if they perform as good as they look! The truck came with Chip Foose 17 " rims, with BF GoodRich all terrain ko's, but I really like to mud, so I think that will be my next investment. Great forum, now my wife does not have to listen to me talk about my hummer! Win! Win!

I have Toyo M/T's (37x13.5x22) and I love them..A little noisy on the highway, but we will get rid of that with the S/C..

[dkhummerh2]

What did the toyo's set you back? Do you have a lift?

we put a whipple in and it whined all the time.....

[dkhummerh2]

I guess I just don't notice it. My exhaust is all I hear. Of course with any throttle added you can here it. But at a standing idle, you would have to listen very hard.

No lift but the torsion key was adjusted to lift the front end 3" for clearance..Slight rubbing with very hard turns so I don't usually make hard turns. The tires were $400 each..

If you are getting 14.5 MPG....dont complain. On my 06 I got 11.6, the 08 is too new to tell yet.

i have the nitto mudd grapplers . i love them.. they are great in the mudd. they are noisy on the road but it doesnt bother me . i kinda like it .. ! they are soft so you have to make sure you rotate them often. but i would get them again. i just love the way they look very aggressive. i have 37 x 20 congrats on your new truck .. youll love it !

And thus the reason they call it instantaneous mileage. My instantaneous mileage cruising on the road will show 13-16 mpg also.

As soon as you flip it to average, I promise you a very different story. With a sc, you'll be lucky if you average 9 mpg.

I usually average 7.6 on highway trips (I tend to drive 80-85) If I drive on the highway in the 55-60 mph range, I will get 11-12mpg average.

In the city, I'll see 8.6-9.0 average.

Good luck.
