Here is what I have found out on my 2.2 hhr, You need to keep the RPM's below 2400. That means typically 65 mph, and really gentle on the starts. If I do I can milk out close to 34 actual, but it does suck getting passed by P.T. crappys !!!!

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.

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

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?

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
