HHR Real World MPG Numbers

Comments

  • I see you have the 2.2 L engine.
    How performent is it? Powerful enough?
    How is it in the hills and mountain driving? (if any).
  • I purchased a 09 HHR 2LT with 7k on it. 2.4L,Auto trans. Liked the ride, not the get up. Upper end pep was ok enuff to buy. Needed room for grand babies.
    I put on a SLR Motorsports module. Easy install. It did not improve mpg like stated, but seat of the pants performance is noticeable. It will scratch the tires from standstill, which it was not even close to before. Mid range performance has increased significantly and top end is the same. On a 400 mi. round trip recently I got 24.8 mpg. That is with 80 mph cruising and about an hours worth of 95-105 mph running with a beamer and an expedition (of all vehicles). I drive 28 mi. round trip 4days a week to work. Highway. City driving is approx 10%. My foot stays in the throttle. I have fun in my ride, and I drive with a purpose.... To get where I am going. Have never gotten below 24.5 mpg. I really dig this little ride. Handling is excellent, except they could work on some torque steer control.
  • How many miles did you get on a tank of gas (highway driving) at with the 2.2 L engine? I usually drive with cruise control @ 68 mph.
    100% highway driving if possible, I've got a cross country trip to do, 3,000 miles.

    I have an 09 HHR LT2 with automatic, just downsized from a mid-sized SUV. Just drove 700+ miles from NC to So. FL via the I-95, very pleased with the highway handling, rides heavier than it looks. Two people with rear seats down and fully loaded, we averaged 26 MPG on regular. Using AC affected the mpg by 1 or 2.

    Starting using flexfuel in FL with mostly city driving and lots of lights and stop signs and I am getting 16-17 MPG. After 2 tanks.

    With my driving style I am averaging 24.5. I have not had a chance to flex fuel yet. Is your mpg still way down? That sucks. Unless flexfuel is like..... a buck a gallon, it doesnt seem like anything special. What the hell is flexfuel anyways? Later.
  • paopao Posts: 1,867
    is your HHR flexfuel capable.....if not..that could be the reason for the lower MPG...it should have the Flexfuel emblem on the back under the HHR
  • laserbluelaserblue Posts: 313
    Flex fuel is used in flexible fuel vehicles that accept both standard gasoline as well as e85. E85 (flex fuel) is a mixture of 85% ethanol fuel combined with 15 percent gasoline.
    But when I'll receive my 2010 HHR, I'll be using the real stuff (gasoline).
    The question is....regular or premium?
    It's a 2 LT and comes with the 2.4 L. engine and I heard that it's better to run it on premium grade gasoline.
    Is this true?
  • dmathews3dmathews3 Posts: 1,739
    I have the 2.4 in my 08 and run reg. all the time. I have seen no difference in mileage or power. I'm sure there may be some but the only difference I have seen is by how fast I drive.

    Hello,
    I am from GM Customer Service. This information comes right out of the 2010 HHR's owners manual. If the vehicle has the 2.4L L4 engine (VIN Code V) or
    the 2.0L L4 engine (VIN Code M) use premium unleaded gasoline with a posted octane rating of 91 or higher. You can also use regular unleaded gasoline rated at 87 octane or higher, but the vehicle’s acceleration could be slightly reduced, and a slight audible knocking noise, commonly referred to as spark knock, might be heard. If the octane is less than 87, you might notice a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service.
    Thank you,
    Mariah GM Customer Service

    Thanks, but I do know what it is. Question is how long is going to take them to refine it enough to be worthy.
    There is no question as to running regular or premium. To run regular unleaded is absurd. The gamble you are taking, compared to the little bit of savings at the pump, and the performance loss, is totally obvious.
    I alternate between medium grade and premium and really experience no performance change. I pretty much run the crap out of my little ride, so I am at least going to feed it well.

    PLEASE explain to me how to reset my DIC?

    I had oil changed and it was not reset, and I am interested in the MPG - how to know what I am getting city vs hwy.

    I have @ 19,000 on a 2008 HHR SS (love it! - well, minus the no console).

    Thank you very much.

    How to Reset the Engine Oil LifeSystem.

    The Engine Oil Life System calculates when to changeyour engine oil and filter based on vehicle use.
    Whenever the oil is changed, reset the system so itcan calculate when the next oil change is required. If a situation occurs where the oil is changed prior to a CHANGE OIL SOON message being turned on, reset the system.
    After changing the engine oil, the system must be reset:
    1. Turn the ignition to ON/RUN, with the engine off.
    2. Press the information and reset buttons on theDriver Information Center (DIC) at the same time to enter the personalization menu. See DIC Vehicle
    3. Press the information button to scroll through theavailable personalization menu modes until the DIC display shows OIL‐LIFE RESET.
    4. Press and hold the reset button until the DICdisplay shows ACKNOWLEDGED. This will tell
    you the system has been reset.
    5. Turn the key to LOCK/OFF

    For vehicles with the 2.2L (VIN Code V) or 2.4L(VIN Code B) engines, you can also reset the system as follows:
    1. Turn the ignition key to ON/RUN with theengine off.
    2. Fully press and release the accelerator pedalslowly three times within five seconds.
    3. Turn the key to LOCK/OFF, then start the engine.
    If the CHANGE OIL SOON message comes back onwhen the vehicle is started, the engine oil life system has not reset. Repeat the reset procedure.

    MPG (L/100 KM) AVG (Average)

    Press the information button until MPG (L/100 KM)AVG displays. This mode shows how many miles per gallon (mpg) or liters per 100 kilometers (L/100 km) yourvehicle is getting based on current and past drivingconditions.
    To reset the average fuel economy, press and hold thereset button while MPG (L/100 KM) AVG is displayed.
    Average fuel economy is then calculated starting fromthat point. If the average fuel economy is not reset, it iscontinually updated each time you drive.

    MPG (L/100 KM) INST (Instantaneous)

    Press the information button until MPG (L/100 KM) INSTdisplays.
    This mode shows the current fuel economy ata particular moment and changes frequently as driving conditions change. This mode shows the instantaneousfuel economy in miles per gallon (mpg) or liters per
    100 kilometers (L/100 km). Unlike average fueleconomy, this screen cannot be reset.

    How many m/p/g did you get with the 2.4 L engine in City and Highway driving?
    Please, not the DIC average but the "real" calculations.
    Ex: miles between fill-ups (from full to almost empty tank) or from where to where? (this city to that city).
  • eliaselias Posts: 1,923
    anyone try E85 in their HHR?
    It's the only E85-capable vehicle in USA availabe with stickshift! hooray!
  • sbeckssbecks Posts: 5
    I am heavy on the throttle, and run 95% or more hiway driving. Last tank, the fuel lite came on at 366 miles. That leaves 2 gallons in tank. So with a heavy foot I do pretty much right at 400 miles per tank. I alternate between premium and medium grade fuel. Really cannot see any significant difference. I think I will try running just mid grade fuel for a few tanks in a row and see what happens.
  • sbeckssbecks Posts: 5
    I have intermittent lack of response from my remote to lock or unlock the doors.
    Sometimes takes several pushes. And different aims. Feel like a retard walking alongside my ride pointing remote at it and pushing button. Any ideas?
    Manual says DIC will inform when remote battery is low.
  • gmcustsvcgmcustsvc Posts: 4,105
    Hello,
    I am from GM Customer Service. I would replace the battery first, and if that doesn’t work take it to the dealership to have it looked at. Thank you,

    We're going on a road trip for 1 week to see our daughter (2 adults with normal cargo)... luggage, gifts, 1 cooler.
    Planning to do only highway driving from point A to point B and leaving very early in the morning.
    It's our first highway trip with our new 2010 HHR 2LT (2.4 L engine). We will be cruising between 65 mph to 70 mph and don't have a slightest idea what could be my fuel driving range on the highway.
    Could you give me your experience with your fuel tank range on the highway?
  • sdasda Indian Land, SCPosts: 311
    It should be ample, 350-400 mi. We just returned from a 225 mi trip (each way). Varying speeds up to 75 mph most 60-70, A/C on all the time, loaded with 3 passengers and cargo. 2.4/auto. 28 mpg. You will probably stop, and fill up before you have to. Enjoy.

    Recently I have noticed a significant decrease in performance and gas mileage. Granted it is a hot 90 degrees and A/C is on most of the time. Gas mileage in my normal driving has decreased from 27mpg to 23-25 mpg. Acceleration is sluggish, though the engine runs smoothly and is running in normal temp range of 190-202 degrees. I guess it is the temperature, or gas formulation. 2.4/auto. Had been using regular but stepped up to premium with little difference in either. Any ideas?

    I just calculated my first m.p.g. on a full tank of gas "filled to the rim" on the starting point and on fill up (not the DIC figures but the real thing).
    My HHR is a 2010 2LT so the 2.4 L engine, it has 683.5 milles on it, still on "break-in" period.
    Drove 439.7 miles with 15.29 Gal. of regular gas and my "Low Gas" signal wasn't on yet, still had 52.8 on "Fuel Range". This tank was 34% city / 66% highway, never went over 62 mph and religiously driving in the city avoiding red light and accelerating slowly and gradually.
    My result is 28.76 m/p/g

    Is this good for the HHR? It's almost impossible!
    And people are telling me that after the break-in period it will be even better on gas than this. Wow!
    I can't imagine how far a person can go on 100% highway driving @ 65 mph using the cruise control.
    Anybody else has good or better mileage than this?
    It's almost unbelievable.
  • dmathews3dmathews3 Posts: 1,739
    I have gotten 36.5 at 60mph on the highway on cruise.
  • ray80ray80 Posts: 1,273
    Having surpassed the 100k mile mark recently mine should be broken in by now ;)

    I haven't done any manual calculations lately but D.I.C. is running over 31 MPG in the warmer weather. I have been using A/C quite a bit or else it it could very well be a tad over 32 during the warm weather.

    My HHR is a 2010 2 LT with the 2.4L automatic

    Are these figures o.k. to you.

    1rst tank I got 23.63 m/p/g driving 80% city and 20% highway.
    2nd tank gave me 28.75 m/p/g driving 60% city and 40% highway.

    We're preparing for our summer vacation with mostly highway driving, I should get something pretty good by these numbers.

    Looks reasonable to me, can vary quite a bit. I think you will see some improvement as you get more miles on it (of course only to a certain point);
  • brodyhntrbrodyhntr Posts: 1
    My 2008 HHR LS averages 28 combined and on highways 36 plus even when its topped out she still get 20 so forget prius or any other hybrid HHR is the way to go
  • mike507mike507 Posts: 1
    I have a 2009 HHR and the power windows would not work. The dealer said a fuse failed because the windows were dry, and the I need to lubricate the window tracks with a silicon lubricant periodically so I don't burn out the window motor. I never had to lubricate power windows in any other vehicle.

    Has anyone had this problem, and where do you lubricate so the windows don't have silicon all over them.

    Thank you.
  • dmathews3dmathews3 Posts: 1,739
    I too of the many, many vehicles I have had through out the years I have NEVER had to use anything on them. Tell him to fix them right or give you a guarantee for as long as you own the HHR he will fix at his cost any power window problems.

    Is this a kid who is just winging it or a seasoned pro? If it's the first, clearly they don't know what they're talking about. If it's the latter, better go elsewhere. Better yet, Go Elsewhere regardless.
