Just wondering if the auto is doing as well as the standard shift? Or the LT2 compared to the LS with the smaller motor?

I am getting an average of 28MPG US general around town driving LT2 automatic, only 800 miles so far.

I have an auto as well and 250 miles. Yesterday took an hour minute mostly highway driving and got around 28.6 MPG.

Just filled up for the first time... in mixed driving I got 24.8 MPG.

on my first couple of fill ups I've had around 28.5 mpg...I just broke a 1000 miles on it and am on this tank doing 27.3 when I got out of the car tonight but I've been doing a lot of harder driving on it seeing what it can do...

Wow, I envy all of you! I'm getting 17mpg! I HATE Miami traffic!

That's odd. I live in oklahoma city mainly highway. My average for the last two tanks is 32.9 mpg. I just hit 1600 miles too :(

ive been gettin on average 28.6 mpg but the other night thru town i got 31.7. i also live in a wide open town as we dont have many stop lights here in northern AZ.

We got 38 MPG (imperial gallons) on a recent trip to the mountains. Saskatoon to Calgary to Revelstoke and return. We have a LT auto fairly well equipped using regular gas. There was NO pinging.

Avg 27 mpg -1800 miles now

Man, I should've bought the HHR instaed of my Silverado. I get 15.7 combined with just under 2000 miles on it. Maybe in a couple of years I'll trade the Silverado in for a 2.0L supercharged HHR.

I have about 1600 miles right now and I'm avg 22 mpg

just the other night

That is a picture of driver information display which isn't accurate , to accurately measure gas mileage you have to fill up the gas tank to a set point, such as second click on gas pump shutoff. Then drive till the tank is near empty, refill to same setpoint, second click on gas shutoff. Then divide gas input into mileage traveled since last gas fillup. This will equal MPG the Driver information display is an estimate of MPG! Usually off by a few MPG.

I have actually found that the DIC in the HHR has been on the low side (at least on mine) I am consistently averaging .5-1.4 higher than what the DIC says. All of my other vehicles have been on the optomistic side.

I geting around 27mpg in city driving. got about 250 miles on it in the first week.

I'm gonna disagree...this is the less accurate measure of the two...the DIC has been pretty much spot on...and I reset it every tank allong with my trip A and average speed

How can actual input compared to miles traveled be less accurate than the on board display? Actual consumption compared to miles is the most accurate indication of mileage. If it works for you, OK, but the proper way is to measure actual input against actual miles traveled.

DIC uses an algoryth based on throttle inputs, driving speed and engine speed, and a few more inputs then calculates an estimated fuel economy. I use the same method parky uses and get between 23.5 to 24.8 MPG.

It's gotta be that the ocean breeze really affects fuel economy.
At only 800 miles on my 2LT, with 95% city driving in Miami, and most trips are less than 5 miles, I'm getting only 18 MPG.
Looking forward to 1st road trip to Disney to see how mileage is. :cool:

I avg 20 to 21 in my LT2

I got my car to say 99.9mpg last night. Right before I hit a huge hill i reset the mpg and put it in neutral. Its a shame thats not my avg mpg. I wouldnt care about gas at all.

31.4

I'm averaging about 27 in town driving, but I've only got about 640 miles on it. :cool:

850 miles on my HHR. So far about 25 MPG. That's mixed highway and town driving.

'07 w/ 2.2 liter and auto trans, only 343 miles on the clock, DIC shows 28.5 avg mpg. This is from tooling around the burbs.

26 with the 2.4 auto

'06 2.2 Auto - 24,000 miles -- I average 27/28 mpg that's mostly highway (65-75mph, some slowing to turn) and some in town driving.

Trip to Iowa a few weekends ago with a tail wind - all interstate driving 75-80 mph we got 32mpg.

'07 2.2L auto - 29.3 avg. (recently started using A/C, was at 30 flat before)

Almost 4000 miles, 2.4 auto 20-22 in town, hope it gets better soon!

Hi All, I have a 07/LS /2.2l/auto ;) with almost 7000 on it. Well to my Big Surprise :nuts: I get 23-28mpg city and up to 38mpg HWY at 80 mile per:eek: , NOW THATS NICE!!:thumb: .....aven11

Current reading is exactly 30.0 MPG with 5700 miles on an '07 1LT with the 2.2 engine.

Our two week old 2007 Silver LS with the 2.2 and auto has just over 600 miles on her now. In heavy start and stop Austin, Texas traffic with the A/C running full time actual mpgs as of this morning are up to 25.8...I'm very happy considering my other ride is a 1984 Chevy K5 blazer full size with working A/C and a small V8 that gets about 11 on the best of days. :guns:

Curtis & Deb :nuts: :breakdanc

Looks like the 2.2's are pretty consistent on the excellent fuel economy.

I have a 2.2 auto and get 26 in town and 31 highway.:smile:

Copied from Gas Buddy...mpg is doing the math, not the DIC. Right now the DIC says 30.9 I did not reset it this time after filling...I'm impressed!

With 2000 miles on my 2007, 2.4 automatic with 17 inch wheels, I am getting 26-28 mpg local short trip driving and 29- 31 on the highway running at about 62 miles per hour, not bad but not great considering its compact size . My 12 year old 4 cylinder 5 speed Saturn will still get 40 mpg highway at 62 miles per hour. Maybe after more break in miles our HHR's mileage will improve.
.

Yes, but the laws of physics still apply... HHR is heavier and presents more wind resistance. For what it is, I think the HHR... your HHR... is getting respectable mpg :beer:

My combined highway/city gas mileage is a little over 28 mpg. I drive about 65 on the interstate and usually use the cruise control.

I'm completely satisfied with that.

My '07 LS has just under 4000 mi, I'm averaging 27.5 in normal driving, and 33.5 on the highway.

07 2.2 5-speed 32.5 avg . Been as high as 35.7 hwy. 4600 miles

fwiw I filled up today and did the math...my last tank gave me 35.02 mpg :eek: That is phenomenal! I filled up at a 1/4 tank..took 11 gallons and had 380 miles on the tank

I am very pleased :thumb:



Goose

In town 24-26 mpg
Highway I've gotten up to 32.3 :thumb:
With 371 Miles so far

LT2 Auto I get 28 in town and 34 on the Hwy. I have 18000 on her

Around town driving, 2.2 5 speed watch my numbers
