Trying to figure out my gas consumption i cant use my info center so just trying to see what most of u are getting..im in canada so my gas is in litres and it usually takes 80 buvks to fill me up at 1.25 a liter so jus rounding i get 80 litres which to u.s is around 22 gallons..as of now im getting 400 kms per full tank which is 250 miles....this seems bad to me but what are most of u getting on average per full tank of gas..not sure of mods matter but i have a air doc intake and magnaflow shorty exhaust minus the cat if i remember correctly lol?

Also if anyone has a link or can post the shift points while driving let me know cuz i think my shift points are off cuz my idle cruz going 50 mph is around 2 -2 an half is this normal...

 

I put about 11 gallons in every week, and every time I've filled up my mpg was 13.45-14.37 which is lower than other people have mentioned in some other threads:

Ever heard of filling up, writing the miles/kms down. Drive it empty, then fill up again. Check the kms you drove on that tank and divide it by the liters on your fill up?
Do you have 35 inch tires, gobi roof rack etc so it seems like you hung a parachute behind the brick on wheels trying to push through air?
Do you drive city traffic? Highway? at 100km/h or 150km/h? Is it 30C below zero?

In other words mileage depends greatly on circumstances, driving style and equipment. So it might be perfectly normal. You drive a hummer after all. They are not known for great gas mileage

 

Nlhummer i get all that, jyst asking to see whats the avg. Ppl are getting i can guage tge difference on my own depending on mods such as tires etc.

 

Same here exactly....47k on '09 and never got any better per tank combo hwy and city.

 

...like I wrote in another post...

I get anywhere between 16-19 mpg on average. I think it has ALOT to do with how warm the car is beforehand though. If its chilly and the car hasn't moved all day, its lower. If it is warmer or I have driven a short distance within the past half hour I get much better mileage. I have no mods, and have stock wheels and tires... a scangauage e is my monitor. It keeps me conscious of my mpg.

I think I will get a tune as soon as I get my cai and upgrade my suspension ( body lift and crank my torsion bars) and tires. I am wondering what the best rolling speed is as well. And the shift points... eagerly waiting the "hummer h3 Yoda" to post the secrets!!!

 

10 city, 14.4 highway (80-85mph)

 

FINALLY!.....Somebody putting up 'real world' numbers like I'm getting!

 

After throwing on the 35's, im about 10 in the city, 14 highway. before the bigger tires i was about 14 city and 17-18 highway

 

It is hard to make cheese out of your scribbles.
By the way 2500 rpms doing 50 mph? Are you putting it in D? (drive)
My H2 has to do about 85 (140km/h) to run those RPMs
should be about the same on an H3
