So I've had my HHR one year. I have clocked a grand total of 6100 miles so far. For the most part, my mileage (on the DIC) is around 19 mpg. Which sucks. I have taken two long distance trips - one to Kenosha in September and this weekend I'm in Clarksville, TN. On the Kenosha trip (once again using the DIC) at real world speeds, I averaged 34.8 miles to the gallon. On the trip down here I averaged 33 mpg. This is a 2.4 model with a manual trans. This was at normal to above normal highway speeds. Not 85 - 90 mind you, my mother (a very nervous passenger) was with me. Does this seem normal? Or is the DIC not very accurate.:(

I have a 2.4 auto and my average on the freeway is 28-29 thats driving 70-80 with some standing traffic about 80 miles one way but if I drive 55-60 easy on the throttle I have gotten just under 34 (33.8) these are all on the DIC but when I hand check my mileage i am usually showing 1-2 miles per gallon better then the DIC showed. The in town driving if you dont do the jack rabbit starts and cost on up to the street lights and stop signs (just take easy and be aware of how you are driving )it will help the city MPG a bunch I have gotten as low as 17 in city but driven like I should be driving any where from 22-25MPG But now that gas is back down I find my self not watching the MPG as much :D
a few weeks ago My wife and I were running really late for the Monterey G2G so I had to make up some time when we got there i was getting 20 or 22 I dont remember but I was flying low LOL:lol: I dont think i ever went below 80 If i did it wasnt for very long

In the SS no matter how I drive I seem to get 22....and thats with 85% city driving....I have checked your mileage manually without the DIC?

I normally get 24-27 in town.. and 30-35 highway. (2.2 motor)

and like andrew said.. manually check it when u fill up (divide gas put in by miles driven on tank) i think thats how u do it

haha close....divide the miles you drove by the amount of galons you put in....hopefully you re set your trip meter at every fill up...

I don't feel too bad now about my 25.1 around town in my SS......I drive like I got a 1.5L toyota snail under the hood.

Chris....

I would guess your city mileage is influenced greatly by YOUR style of driving.

With the 2.4 and the VVT, once your RPM exceeds the operational point, the engine uses more fuel.

Try minimizing your acceleration efforts. Maybe no more than 2800-3000 RPM (I believe the VVT begins operation aroung 2600-2700).

I have a 2.4 auto trans and ROUTINELY experience 24-26 MPG. But I watch my RPM's also.

Thanks I appreciate it. Of course jack rabbit starts are so much fun -

Remember, the reason that city mileage is lower (except on hybrids) is idling at traffic lights and therefore having to start up again from a stop, over and over again. I have the 2.4 automatic which I believe is advertised as 22 city, 28 highway. Remember also that these are estimates. I usually average about 25-26 (right in between the estimates) MPG per tank of gas which includes city and highway and bumper to bumper highway which REALLY hurts the average. I reset all that is resettable on the DIC every time I fill up. My fuel range usually says about 400 miles which on a 16 gallon tank works out to..."drumroll please"...25 MPG.

:steering: What Snoopy says. The lock up for my 2.4 auto is around 40 mph and it will run at 1500 rpm. I rarely take the car past 2500 rpm in city driving and get around 26 mpg. At 70 the car is running around 2500 rpm. I've averaged 30.3 mpg combined mileage since I've owned the car. ~39K miles

2.4 auto mostly city driving. With A/C DIC shows 17 - 18 not using air 18 - 19.
NEVER saw 20. Tire pressure is checked every week always 36 - 37 lbs.

Umm...jack rabbit starts? Maybe I'm an idiot but humor me please...

Jack Rabbit start = quick off the line instead of easing away from a standing stop. Horrible fuel waster.

yeah .. occasionally ill squeel my tires leavin a light to mess with some ricer or ghetto wanna be car :p:

BUT normally i take off slow so my gas mileage avg . stays up :thumb:

I have been able to get a consistant 35 m.p.g. (highway) out of my 07 HHR 2.2 manuel trans. observing posted highway speed limits 65 and 75 m.p.h. If I push it to 80, I can still average 33 m.p.g. on Colorado rural roads.

That sounds way low to me. I have only had my 06 2.4 auto for 2 weeks, but it is currently getting 24.0 in mixed driving in the winter here in Ohio. On the highway it has gotten from 27 to 31 based upon speed, temp and headwind. I would expect it to average at least the EPA estimates in Florida. Maybe have the ECU checked out and have the car tuned to stock?

I think it's your math skills. I rememner seeing someone here that SAID he was getting 40mpg

just a tip to people complaing about city mileage. at least with my 2.2 auto 40 mph yields insane mileage. i tested it and reset the dic and ended up with 39 mpg for 10 mins on a flat road. just carefully get up there and cruize around at 40. around here that is speeding but most people go even faster than that. in town he cops really dont care.

For the SS drivers learn how to drive by the boost gage if you want to max your milage..keep it below "o", can't always be done but after comparing you'll find the zone to work with and sometimes you have to feather off a bit to get it where you want then ease it back up to maintain milage.Play with it and you'll see.

even driving with it's tacked right at 0 on the highway and driving on flat surface its about 20-25 on the INST reading....the best results I have found when you still have to be giving it a little bit of gas is when its right around the 10 in vaccuum....that seems to always get between 40-60 inst.

Under certain terrain and conditions, i have and do. Not the fastest way to get places, but not all that much slower. Search "absurd mileage".
